Uh, no. She is from Maryland.

RP send me one of the old designs of the AFSC So I can show it off at NOPI Nationals in September.

I will send it back to you after nationals

That would rock if somehow an RX-8 fitted with an AF could make it out there! I'm going to NOPI Nationals just to check out all the cool stuff...and the AF is definitely cool!
I'm one of those guys that has been reading this forum for a long time but never posted anything...i'm sure there are quite a few of us out there...but i'd love to be able to see an AF in person...i've seen the pictures and they look great so far but they just aren't the same as being able to stick your head under the hood and take a peek. Since i'm posting...I might as well say great job so far, i'm glad you're taking your time to do it right...and this forum has been quite the interesting read in the meantime!:)

Just wanted to show off the unit and promote AxialFlow Engineering a bit; since the Club is in a special area and may get some TV coverage. :ylsuper:
However that may be more publicity than RP wants right now.

Can we get a video or a sound clip? Does it sound like Hymee's?

no it doesnt sound like hymee's. thre is a sound/video clip(i think) of it running on the test stand back when hymee visited and they lost Torque

Yep - that was me responsible for that. The video bit, not losing torque - I'm responsible for finding the torque we all need :p:

It sounds more like a jet in the video, not at all like the screw. As an axial flow should sound, since that is what a jet is anyway.

Cheers,
Hymee.

beers :beer:

I remember reading and posting about torque going missing just missed the link to the vid of the unit on the test bench

Now that we are close to the light at the end of the tunnel, any thoughts as to whether a high performance clutch is necessary with the Axial?

I seem to remember those clutches being like $1000, which would certainly up the cost of ownership.

Any other costs/parts needed to be replaced we should know about?

Damn this is exciting. The Rx8 is about the only car that fits my needs for a small 4 passenger vehicle that handles well, and it seems like other than poor gas milage, the 8 is about to loose it's only other possible drawback, (lack of HP)

If I do indeed end up Axializing my 8, I guess I will end up keeping it at least another 8 years (provided it holds up well) My next car, I expect to be be fusion powered and be able to fly short distances.

Lots of turbo owners don't bother till the clucth gives up .

Just use it as an excuse for a lightweight flywheel . less than $900 for FW/clutch combo .

Wow RP, it looks like this project is REALLY coming together. Can't wait to see it at SS9.
hmmm, maybe Spice Boy and I will have to come out to your shop and take a sneak peak at it...

All praise be to the RP. Thank you, thank you.

Get that supercharger to market ASAP, I want one. Awesome.

I took my RX-8 in for service yesterday and for the first time they asked me if I had a turbocharger or supercharger on it. I told them Not yet, I was waiting for the warranty to expire. They said Mazda is cracking down on such modifications.

But in any case I only have 2500 miles untill the warranty expires, which should be good timing to install an axial flow supercharger I think?

on another note though, has anyone else experienced a cutting out at high rev's (above 6500) when accelerating? it almost feels like a fuel starvation problem. That is why I took the car in. I need it running well as a baseline before I go supercharging it.

Couldn't they just look under the hood?

Couldn't they just look under the hood?

this was the service writer, right off the bat.

I can understand Mazda being wary of forced induction or ECU alterations, but basic bolt-ons I'd think they'll care less about. Any dealership I've ever been to has never complained about my high flow cat.

good luck,

You just look like the kind of guy who would cheat. :rollingla
After all you have all those noisy bikes don't you? :ylsuper:

Any progress yet with the new ECU?

so they saw in the ECU memory a misfire condition they said, but they will not work on it until I put the stock aircleaner back on.

it feels like fuel starvation, plugged fuel filter, tired fuel pump, something.

so now I have to find which box I packed the aircleaner in and restore it to stock.

You just look like the kind of guy who would cheat. :rollingla

yes, I do have them durn noisy murder cycles, five of them last count if you only consider the running ones....

The length and content of this thread is "special".

What about some projected numbers on the axial flow supercharger? 0-60 times, horsepower increase, etc... ??? Please.

Don't complain about the length of the thread.

If you had read the thread.... you would see that Richard won't make claims about the horsepower. He has to finish before that info comes out.

Richard has been kind of quiet lately which makes me think he's working his ass off and probably making good progress.

*waits patiently*

he's definatly trying to finish for 7 stock :rock: :ylsuper: :rock:

Richard as usual is working hard to make it a nice kit that does what he says. I think we are going to see something really cool at Sevenstock this year!

I hope it comes with a cool little plate on it like the older models or engraved.
Say something like
Built by Richard Paul

then maybe some cool/corney line!

I like the little things.

This is like the recall notice. We all knew about it beforehand, and people are freaking out left and right. Wanting to know what's taking so long, why can't they get the new flash right this very moment.

I'm starting to think we'd be better off if our first word about the recall came from the official letters.

He already got the first ID plate.

It was from HYMEE

Read all the posts and you will be informed. :eek:

That is not punishment for complaining like this is some recall thread :wallbash: :icon_no2:

it will help you appreciate the research and development that these engineers have to do.

Wow, 260 pages later and still no Supercharger.
Remember that he designed this from scratch. He couldn't just go out to a store somewhere and pick out the supercharger trim that he wanted to and then just assemble it like a small puzzle. This may work with turbos but not with an axial flow. He had to design the whole thing from nothing. That takes time to get right. Then combine this with normal development issues/problems/surprises and you've got 2 years and 250 pages worth of thread. Of course if this thread never went off topic, it would only be 7 pages long! ;)

Just like SUV owners complaining about gas prices even though the very act of them having an SUV is what made the gas prices high in the first place :)

Didn't vote...neither option suits me.

Read it from day one. Had my first internet fight in there. Got inspiration from that thread to start the 500 post thread encouraging Richard's short shifter project. Named my son after Richard. Started a career in jets when the thread ran off-topic and talked about military fighters. Was reading that thread when Al-Zarqawi was killed. Put on 5lbs reading it. Had arguments with my wife over it. Solved complex algebraic equations using it.

Did you know that by taking every second word out of post 2655, you make the phrase "Richard is eating supercharged jets for lost Torque"???

Your a funny guy Gomez, is there an easy way to go to a certain page, NO. Did I fall for it? YES. :wallbash: :rofl:

Intriguing...hopefully eating supercharged jets at least keeps plenty of iron in your diet! :cwm27:

Joking aside, you can bet your exhaust I'm gonna keep my eyes on this SC...this could well be the first major HP mod I get...

If it’s going to be introduced at this year’s seven stock I think we can wait another two months, and if the quality is as good as his short shifter, which I just installed yesterday :wiggle:, then we will get an excellent product. I just wish the install could be as easy as the shifter. http://www.rx8club.com/images/smilies/smile.gif

Cobb tuning was bought up a few post ago. Some of you may want to rethink that. From what I know of Cobb, he is a pretty consevative tuner. Sounds reasonable for someone putting a new toy out on the market. But from what I know about Cobb, you have to use his maps and can not tune one your own. To get a custom tune you have to go to a Protune authorized dealer/dyno which is major buckage and they are found very few and far between.

As Polak said...
http://cobbtuning.com/legacy/ap-streettuner.html

and unlike the interceptor, if Richard could work with them to get a base map there is no need to end user tuning as the fuel trims will adjust the afr to what it should be all by itself - just like it does from Mazda

... and for what, 1/4 the cost of the interceptor?

and 1 less component to break

Jesus,............................................ ......................

Friggin H .................................................. .

right - it's about 600 or 700 for the flash uploader and another 200 for the software if you wanted to make changes. We've discussed this before, several months ago he was saying he was hoping for working prototype by the end of the year, so it's still a ways off. But it's not vaporware since he has units working for several cars already.

At any rate, we're going off topic in this SC thread..

Personally I'd love to just flash the ecu and be done instead of trying to find a local shop that even knows what a rotary is and then having them try and tune it without blowing up the car. I don't have a problem forgoing a few hp and using a standard map if it save me buying a new engine with the SC.

Saw RP on the vette site promoting the Axial. Can't wait to see the final product.

Everytime I try to plan out mods on my car, I keep putting it off in hopes that this SC will be out soon. In fact, I can't make up my mind on my suspension because I can't decide if I want to spend the money and get what I realy want or save some money for the SC and get something less expensive.

I do love the idea of a super charger. Give me more power on the bottom.

Since the ideal compression ratio for FI is around 8:1, is there anything like a revised rotor for lower compression? Just a thought and maybe someone else has asked the question before. I have no idea what it would take to R&D something like that and what it would take to revise the PCM but with lower comp. you could pump up the volume.

There are no lower compression rotors available for the Renesis at this time and the likelihood of someone providing them outside of Mazda is about 0. Cost prohibitive doesn't begin to describe it.

Could you plz get the RX-8 and the S2000 versions done first...... :angel:
al lot of us have been waiting a long time for this to get done.

but I got to admit the Corvette market probably has a better profit potential initially than the RX-8/S2000/import scene.

yeah you can charge them double for the same thing:)

As long as the intake charge is cold enough, there's no reason to reduce compression ratio. If I was worried about detonation, I would add an intercooler and/or use water injection, before working on the compression ratio.
If one were to use a turbocharger, one can argue that with a lower compression ratio there's more enthalpy (pressure) left to run the turbine and thus the turbocharger itself can produce more power (shuffle more air). But this is not a turbocharger application.

Hey RP. go for the "Musium Delivery" it is well worth it. They sell Vetts worldwide now. I have been to dealerships in Monaco and London. They build 39000 per year. I think you will have a good market there, as well. Just make it where it will fit on a C5 or C6.

Since were all waiting for the release of this baby. I'm wondering what HP numbers RP was thinking of for the RX-8.

Are we going to see 300 to 350 HP? More? This is very unoffical, but it would be interesting whose guess will come the closest to the real numbers when they are released.

Just for the record, I'm thinking RP will hit between 320 HP to 350 HP (SAE) on a production model for the average RX-8 M/T. Just enough, not to hurt anything, but plenty fast.

What do you guys think?

i think you are very wrong... rp is looking to make the car more fun to drive... at a moderate cost...

no change of injectors... my guess is ~ 250 whp...

if you are looking for 300 + this is not for you... the answers are in the thread, and yes i know it is huge...

beers :beer:

^^ Precisely.

250 WHP is nothing to sneeze at. A little bit more, like 275 WHP would be even sweeter. That would translate into a nice HP (SAE) rating too, somewhere slightly above the 300 HP range. I'm of course hoping for 320 to 350 HP (SAE).

I want to see a little more than 275 WHP for the RX-8 M/T, because that would mean the kit would bring RX-8 autos into higher performance levels than people expect and they have further to go to get there. I don't see why something like an Axial Flow Supercharger can't do it. But, of course, we have to wait for the kit.

With the kit being easy to install, decent price, etc... it would make itself a must-have.

I would be as happy as a puppy with 2 peters for 250WHP.

I am wondering how well the AccessPort will be with the AFSC. Will a seperate boost controller be needed?

I'm thinking 264 hp.

As long as the price is right and I can do it in my garage, I'm sold!

These kits (and all others) are based around 3 things...

Power
Price
Reliability

The customer gets to choose two of them. I guess development time can be thrown into the mix as well.

Hymee.

Oh yeah, I remember RP mentioned to me that he's aiming for somewhere like 100HP on the crank increase and around 50HP to the wheels

Ok, I'll break the silence. At this time though we are not ready to call final numbers for customer units my best guess is plus 85-90 at the wheels.
Now I think there is going to be some help from better exhaust meaning hign flow cat or midpipe. That is nothing different for the 8 then anything else. You want to make 50% more power don't you think you need to get that much more exhaust out?

I have had some inquires from people asking about pulleys, I have yet to be convinced that they add anything you can measure. Then of course it slows down the supercharger when you get one. It's a no-brainer.

If you must do something right now get the exhaust mods forget the pulleys.
Resist getting any computer componants as that is being solved as we speak.
If you already bought a controller we will try and help with reprograming but there is no promise of ready made maps for final tuning.

Air intakes will not work with this unit as we use some of the room for other things. The kit comes with it's own intake. Same goes for the strut bar, it's in the kit, others will not fit.

265-270 at the wheels. Not bad at all.

Making anything for the AT? :naughty:

I have been putting off mods to my car to wait for the SC. I am about to start on the suspension (just tripped 32k. It's beyond time.) and have been trying to figure out the exhaust for about 6 months. Other things are tempting, but I geuss I will hold off and wait.

If I am a REALY, REALY, REALY, REALY good boy will Santa bring me one for Christmas?

Ok, I'll break the silence. At this time though we are not ready to call final numbers for customer units my best guess is plus 85-90 at the wheels.
Now I think there is going to be some help from better exhaust meaning hign flow cat or midpipe. That is nothing different for the 8 then anything else. You want to make 50% more power don't you think you need to get that much more exhaust out?

I have had some inquires from people asking about pulleys, I have yet to be convinced that they add anything you can measure. Then of course it slows down the supercharger when you get one. It's a no-brainer.

If you must do something right now get the exhaust mods forget the pulleys.
Resist getting any computer componants as that is being solved as we speak.
If you already bought a controller we will try and help with reprograming but there is no promise of ready made maps for final tuning.

Air intakes will not work with this unit as we use some of the room for other things. The kit comes with it's own intake. Same goes for the strut bar, it's in the kit, others will not fit.

$?

50-60 bucks per horse would be my guess

oh jesus, damn richard, now you've gotten me really excited, I kind of wish that you had kept quiet so I can at least wait in peace. Now I'm going to have trouble falling asleep for the next month.

Can you make smaller S/C pullies so those of us with pullies can get the same performance as those without? I still think that -full alt and - full a/c drive would do the S/C good.


Now to the store to buy a few dozen Kleenex boxes...

RP has spoken. Don't do pulley or intake. Get new exhaust. 85 to 90 more to WHP. Oh yeah baby! Must have kit!

Hey (before I get too happy), will there be a kit for RX-8 Autos? Hoping Santa hooks me up for Christmas.

Also, might be silly question, will this kit have a switch so we can turn the SC on and off. My concern is gas mileage and being able to get boost when I want performance and to go easy, to save gas.

that switch is called the accelerator pedal. you operate it with your right foot.

Many, many pages ago it was stated that 4port support would not happen. Whether that has changed...? Doesn't really matter to me anymore. There will be other options.

wow that sounds nice. its cool to know what stuff we shouldnt buy: pullies, intake or strut bar. and i was just looking to buy pullies or a new strut.

is it funny so short after RP says this that there is already a couple people asking about it for the a/t, including me

that switch is called the accelerator pedal. you operate it with your right foot.

Hahaha... I was thinking of something along the lines of the Blitz supercharger kit where you could choose boost level.

That would be sad if RP will not support 4 port Auto's (as there are a number of them out there). Can anybody confirm if the 4 port Autos will or will not be supported?

I'm pretty sure I read earlier in this thread that RP was not planning a 4 port kit.

My post earlier asking if he was working on an AT kit was a lighthearted joke.

We can make smaller pulleys but that would lose the belt wrap that we want. Bigger accessory pulleys are ok just don't make the crank pulley smaller.
Interesting thing about the auto is that we have had a few requests for them and I think there is someone out there who is looking into a manifold for four ports.
The kit will work for the auto if you make a manifold. We can't do it because we will never get our money out of it. Somewhere out there someone knows a fabricator who will make a couple of one off parts.

Zoom44 is right, with this setup off boost is when you do not have the throttle open. When the throttle is closed nothing is getting in so it does not have anything to compress. Therefore it does no work, the rotor is spining in a partial vacuum and uses almost nothing to turn it. There is one part turning in a vacuum on precision bearings, nothing else to use power. Oh yea, I forgot this design has a small planetary gearset built in. Very little power is used there when no load is on them.

Give you an idea of the size picture a three speed bicycle hub. Maybe a little bigger and wider and for sure a lot more precision. But that gives you an idea of how little power the SC draws.

The max HP numbers arent really important... 80-90 more whp is enough, wat the supercharger gives is a lot more low end than the greddy unit, and borrowing the dyno from hymee supercharger, we'd still get the stock power/torque curve, which is excellent!

well thats cool too. atleast its possible and its not some crazy outlandish custom job :mdrmed:

whoa, this thing is going to be AWESOME!! RP, will we still see the final product at SS9? (for sale?)

Somebody has to do something for the Autos. Anybody working on the 4 port manifold want to step forward?

Autos are a huge market percentage of the RX-8 market. The Auto guys are the ones who will be craving power the most. M/T 6 speed guys are already walking around with 230 HP to 250 HP ( I know, but that was what Mazda said, and you might get it back by flashing the ECU). The RX-8 Auto guys are the ones walking around between 190 HP to 215 HP (depending on country and model... mine is supposed to be 210 HP), so the superchargers will be the thing for this group.

If the at guys wanted power, they shound't have gotten a auto in the 1st place.

I cant wait to see it next month! ^.^

Edit: 4k posts! :rock:

If the at guys wanted power, they shound't have gotten a auto in the 1st place. It isn't always that simple. :spank: I got my AT for free as a gift, and I COULD have paid for a MT but that makes no sense.

Please stay on topic and avoid another MT vs AT thread.

If the at guys wanted power, they shound't have gotten a auto in the 1st place.

Lord... People get the auto because of traffic ( i can drive a stick, its the bumper to bumper traffic that I deal with that annoys me enough to not want one), to play with their girlfriend while driving (try it sometime), they don't like being bothered with shifting constantly (not everyone lives on wide open country roads), need to focus on kids in the car, to focus more on watching the DVD player, etc... Don't forget that the RX-8 Autos also have a manual mode, which is not the same M/T, but provides more performance and control if wanted.

The RX-8 is unusual in the sense that while other sport cars have kept the auto performance close to the manual, Mazda (in their lack of wisdom at the time) decided to de-tune the RX-8 Autos because they were arguably too lazy to come up with a transmission and torque converter solution. By the way, put a custom torque converter in an RX-8 Auto and it would be like a different car and still Auto. For the most part, the problem wit Autos is not the engine, but the need for an Automatic Transmission Fluid Cooler (which is kind of easy to get and cheap) and the need for a custom torque converter to handle higher rpms.

Anyway, all this does not stop the demand for Autos or Autos with more power. An RX-8 Auto that has 270 HP to 300 HP would be the best of "all worlds" for many drivers.

More powerful Auto RX-8s would only increase RX-8 sales (thus Mazda did the 6speed Auto RX-8, but of course people want more power) and anybody that can create kits for RX-8 Autos owners craving more power will only be putting more money in their pockets.

RP appears to have a killer supercharger kit. Trust me, if they can do something for Autos, they will pick up some extra cash (including mine).

funny...every (major) modification I'm considering for my 8 is RP. which is cool. :)

also: Holy Zen! 4k posts! :D

Bumper to bumer traffic, play with your g/f while driving, watching a DVD instead od driving, playing with your kids instead of driving.

Dude, I think you are a prime canidate for public transportation.... Just sell your car already before you kill someone.

Yeah OK. After you sell your RX-8 first (or buy one). Who are you, RX-8 driver of the year?

I just threw down some reasons why people get Autos. If you don't want to take my word for it, than take a poll of Auto users. If you just are a "stick or die" Auto hater... Dude, grow up. Life is too short to hate.

You are not going to stop RX-8 Auto people from putting a supercharger in their cars and owning RX-8 M/T that don't have turbo or a supercharger or just having plain fun driving their car.

Just drive your RX-8, have fun, and be the professional driver that you are. Me and others, will still do what we want.

Peace and Love

wow. feel the love. >_>

now...about that SC...I think I may do a favour for the auto folks and see if anyone in the area can machine a manifold for the auto folks. I drive MT myself, but even AT drivers want a bit of exhileration sometimes. that and I do know some killer shops around here...I'll let ya'll know if I find anything. :)

Amen staticlag. I've always wanted to find out the accident rate of people who drive manual vs automatic. I've always thought that having to pay more attention to the driving experience (manual) makes for a safer driver.

Oh, and buying an automatic so you can "focus more on watching the DVD" WTF are you joking?

Ok, I'll break the silence. At this time though we are not ready to call final numbers for customer units my best guess is plus 85-90 at the wheels.



That's pretty good for a super charger. I guess it doesn't eat up very much hp at max revs huh?

Auto people are not car people. :(

Its not that M/T are any better than Autos it just way sportier to have a M/T. You think of sports car you think stick. Autos are great and all but i feel like i have more control w/ my M/T, and that what i like about the M/T.

its all kool

need...to focus more on watching the DVD player

This was a joke, right? :confused:

If the at guys wanted power, they shound't have gotten a auto in the 1st place.

the same could be said for the 6mt...180whp woo woo. lol

if you are watching DVDs, talking on the phone, playing with their girlfriend you dont even deserve to be DRIVING a car, let alone an RX8.

i wonder at what point people thought that driving was a secondary task. I see bitches on cell phones, putting makeup on, and just all kinds of random shit. If you have a DVD player in the car, its for your kids or your passenger NOT you, you dumbass. I dont want you wandering into my oncoming lane and having a head-on beacuse you wanted to see adam sandler jumping around like an idiot. The worst ive ever seen so far was some old crusty bitch reading a BOOK as she drove down the road.

Oddly enough it strikes me that the type of people that want to watch a movie, play video games, get a BJ from their g/f as they are driving down the road are the 1st people that would jump out of their car yelling "WTF is your problem hitting me/getting in my way".

If i need to talk on the cell phone I put it on handsfree speakerphone and stick it on the visor or something. And even then im very short with whoever im talking to while im driving because i actually want to get back to DRIVING. Until the day there are automated systems in place to drive us around without human interaction I think very lowly of anyone that wants to fuck around and do anything BUT concentrate on driving while they are driving. You can kill someone because of this shit man... its stupid.

You can kill someone because of this shit man... its stupid.

Agreed.

like sports cars? Got an auto as a gift? Trade it in for a MT. If you kept it, you didnt need a sports car in the first place. Get a minivan.

Enough guys, this thread is already to long I get shit about it all the time. :banghead: RotaryGod reads this thread so don't be supprised if this stuff gets deleted.

Geez... you're not going to win any debate with that logic, genius. You see this all the time from auto drivers, too... they don't realize there is more to driving a stick than moving a gear selector around... you actually are forced to pay attention to driving, God forbid.

And to you previous post... I think you're really overestimating the market for auto owners that are willing to modify their vehicles to this level... it is certainly going to be a small fraction compared to MT owners.

OK peoples, that is enough about auto v's manual in this thread! Take the mass debate off-line please.

Cheers,
Hymee.

Those numbers are awesome. Now I have to sell my exhaust/struts/pulleys. At least I don't have an intake to worry about selling.

So I'm assuming we'll see the SC next month right?

Hmmmm... how am I going to convince the wifey on this SC? Anyway, can't wait for this-keep up the great job RP !

Those numbers do look really good. Now I'm glad I just concentrated on upgrading the suspension and exhaust while leaving the intake and pulleys alone.

The AFSC is a mod I will do to my car, but I'm about a year out. The backlog of orders should be down by then.

I think I signed up as #3 or 4 on the list earlier...

all i have to say is 4cyl hyundai tiburon kit ftw.

oh and dont watch dvds while driving.

bjs are ok.

RP finally mentions numbers and everyone has to go AT vs MT. Jeez.

C'mon people, look at those numbers! You should be excited :)

there is going to be some stuff for sell on the parts thread.

Now THAT was funny!! :mdrmed:

Do ya really need a wife after all? LOLThey are just extra weight and weight is the enemy of performance which means your wife is your enemy!! And what do you do to your enemy? You get rid of 'em or enslave them. So the correct logical solution to your problem is to put your wife to work to pay for your supercharger. :rock:

We could really get of the thread here!

shipping. a novel idea! I'll discuss it with the shop's owner and see what he has to say about it...certainly the thought of being able to serve a global market and having the monopoly on the AT 8 manifold could be appealing. *evil grin*

axial flow supercharger thread!!!!!! we have pm here..

beers :beer:

but this is quite related, seeing as we're discussing a critical component to the AF SC for the auto variety, thus expanding RP's scope of support as well as furthering the technology's R&D...:)

o rly,

ok, carry on... i guess all the other ems solutions that he has will not work...

let the guy finish the job.... :doh:

got to walk before you can run....

beers :beer:

well...yeah, but he said himself the auto needed a manifold and that he wasn't producing it... just trying to help out with a cost effective solution that works for everyone, you know? o.o;

with that said, we'll see what the shop says. :)

Why couldn't you just use his 6 port upper manifold and bolt it onto the 4 port lower manifold? Just block off the passage that would go to the auxiliary ports on the other engines. I don't see the issue with using his kit on any engine.

Frynge, I guess no world RX-8 4 port manifold domination for you now. LOL :bootyshak

So the numbers Richard mentioned mean that we would be getting an almost 40-50% increase in power?

florida does not need carb certified, we are very lucky. if cali falls (let us hope not) will puerto rico become a state to complite the flag. :scratchhe

I'm still waiting for my afsc on my birthday at the beginning of oct.. RP you promised :)

Will that work???????
It should. Then again, leave it to Mazda to do something weird. The 4 port lower manifolds as far as I know are nothing more than the 6 port manifolds with 2 runners removed during the casting process. If this holds true, all you'd need to do is supply a small blockoff plate that bolts onto the upper manifold bolt holes. Greddy supplies this plate with their turbo kits to disable the auxiliary ports since their turbo has crap for airflow. Just come up with a different state of tune for each car.

After I finish my comfort mods I'll be saving up for one of these too! :rock:

EDIT: Just subscribed to thread

EDIT 2: Whomever has the box of tissues... pass me one. (Shit someone said Rx-8 owners where mature, guess I just "blew" that one out of the water.)

i hope the blocking off works for this application. thank you RG :worship:

I do too. It's just a hunch as it appears it should work but until someone actually tries it and verifies it, don't get too excited. It's just a possibility.

Frynge, I guess no world RX-8 4 port manifold domination for you now. LOL :bootyshak

Curses! I could have made it too if it weren't for those meddling gods! ;D

actually, I hope it works. a simple solution is always preferable. ^_^

ok im only only at half mast now :mdrmed:

4 port guys here's the deal- buy the kit. then get the local hotrod shop to fab the blocking plate and try it. if it doesnt work they can find someone to do the manifold for you.

Isn't that like..."buy the kit and hope it works, if not pay someone to make it work" ?

No thanks. Want my money? Sell me something that'll work out of the box. Otherwise there are other kits that will.

It'd be nice if it did work, another option is always good. But it's kind of stupid to ask me to shell out several thousand dollars for something that might work. Custom fabbing a manifold will cost a large % of initial kit cost, that would put the price way out of competition with the others. Not to mention you'd be tuning from scratch, or near enough.

I'll be here for a little while longer, with a wait and see what happens stance. Pettit is the front runner in my wallet, atm. I'd love to have the AFSC under the hood, but I'm not paying for a halfway job.

-------------------------

Determining whether a blocking plate would work should be fairly easy. Just compare the 4port manifold with a 6port manifold (or RP's manifold). I don't know anyone with an 8 (6 or 4) near me, or I'd do it.

Therm: Ease your jets "Turbo"! You're not paying for "a halfway job" because this kit is NOT intended for you Automatic guys....it's a full job for the Manual Transmission cars. I'm not knocking the A/T, it's just that plain and simple.

GL with the Petit if that's the route you take, it should be nice.

I was responding to Zoom's suggestion. Hence the quote. His idea makes it "paying for a halfway job." I'm not knocking the AFSC or RP's efforts in any way. If RP goes to the effort to find out if it works on 4 ports, and it happens to, then great. If not, then no skin off my back, as last week I didn't expect it to be an option anyway.

The flange shapes for the 4 port and the 6 port lower manifolds look identical. That's why I feel they should work.

I now have access to a privately owned foundry through a live steamers club I'm in here in Houston. I am going to slowly start learning how to cast many parts. Ultimately I would like to learn how to create molds for and create new intake manifolds for various projects. Don't get too excited. It's not something that I am putting any effort into right now but I do have the ability to if I want to use it. Someday I'll get around to it.

Interesting... See all you AT owners, if this holds true, you'll actually be able get your blow jobs and go fast at the same time LOL :bj:


Damn that was just wrong, funny as hell, but so wrong.

Axial Flow SC for Christmas for AT owners!!! Well, if somebody can come up with a soluton. If they can, I'm sure a number of AT owners will go Axial Flow.

but the gearshift knob on my MT vibrates so nicely being mounted directly to the transmission and all.

Not sure about after I get the axial flow on, but with the K&N Filter and intake, it idles nice and rough.

Which K&N do you have? The idle roughness can be fixed by installing at least one of the original 2 intake screens around the MAF.

Which K&N do you have? The idle roughness can be fixed by installing at least one of the original 2 intake screens around the MAF.

I did not know there was a choice. I bought the very first one I could get, my speed shop pre ordered it before K&N released it, so it would be the first one

when I installed the K&N at first there was only noise, no noticable improvement.

When I removed the duct work from in front of the bulkhead I got about 1-2 mph at the end of my freeway on ramp I use for testing.

I know, not very scientific, but it works for me. I use it for both my RX-8 and my El-Camino. Problem is I have run out of speedometer on the elky, so I have to go by engine RPM which is harder for me to gauge.

The first K&N intakes had idle issues. You need to find a way to integrate a stock screen from the original setup back into the system before the MAF. This should help.

I just use a K&N Panel filter.

if they would of made the front of the intake filter material insted of carbon plastic it would have been so much better or even a replacement for that top, kind of what the new one is. so air from the front and the sides would rush in, and that would probably be best for this AFSC if it fit

Well guys,

Less than four weeks for the AFSC show at SS9!!!

We still plan on showing all at 7-Stock.
Even a supprise visitor with goodies in tow.

come on richard....give me the skinny on it!!!

Is it who I think it is?

You wanna spoil all my fun?
I mean how many cheap thrills does a guy get these days?

I know its the Hymster from Downunder With Blonde wig his Kaki Shirt and Shorts a rein carnation of Steve Erwin :ylsuper: By Crickey trying to get a free entry to the US , Peddling his Twin Screw Supercharger and a few other goodies :cool:

Only the Limies get British humor. Don't try it on the Australia thread.
In fact I'd like you to delet it from mine, if you don't mind.
No offence, I love the British and some of the best times of my life were spent there. It's just a little to soon for this though.

jokes should be allowed about anything and at anytime...however tact should also be shown.

anyway deleted as requested, although i thought it was a goodun.... :naughty:

BTW Aussies above anyone can joke about anything and hold nothing sacred!!! Its one of their best qualities.....

Thank you and yes I know the Aussies can handle humor about most things, in fact they are great at it. Just in talking to a couple of our resident Oz folk these past couple of weeks I can tell you they are very sensitive to this one topic and grieve on a national scale.

Don't tell me he posted a blaphemious post regarding Peter Brock?? Crikey!

Cheers,
Hymee.

No, but he died the same week.

Ouch.. Bad week for Australia then...

My sympathies go to all affected by the double loss.

oh so true, just the other day at the uni's comedy club there was an aussie comedian who was absolutely brilliant!! (tho being 7ft tall and built like a brik outhouse probably helped tho :p: )

Richard,
Back to some wing talk - what is the reason that an axial flow compressor has many small wings per rotor as opposed to fewer (and larger) wings?
And the reason why you have a relatively narrow (ring shaped) opening is because you want to make sure that the individual 'wings' deal with the same air speed (inner and outer diameter), right? Does the air speed need to be in a relatively narrow range in order for the 'wings' to work properly?
Can you recommed any books about this topic? (Just for curiosity)

It's the same concept that most modern gas turbines use. I would look up text books on jet engine propulsion to get an understanding of the aerodynamics involved. There are some good AIAA (American Institute of Aeronautics and Aerospace) books I used back in undergrad that were helpful.

Can't wait to see your finished product Richard!!

Hi guys. FIrst of all, apologies for posting on an RX8 board. i'm actually an S2000 owner (and so fellow lover of 9,000 revs :ylsuper: ) but accordingly I've been lurking on this thread for far too long, hoping that you RX8 boys get Richard's Axial Supercharger soon so that Richard can focus on developing it for the S2000! :)

However, things have now come to a head - a British group buy for another well established S2000 supercharger is closing next Sunday and so I have to decide whether to wait for the Axial SC. Just two questions Richard (but admittedly they are difficult):

(a) How long do you envisage it taking before you will have developed and be able to sell the Axial SC for the S2000?

(b) will it be available from the date (if at all) for a RHD car?

Right, back to RX8 chat - we don't see many of them in the UK due to the price of petrol and the RX8's thirst :( I like many of its design cues though (particularly the front end, reminds me of another car ;) ).

Craig

:) Some of the kits I have seen on the S2000 have me turning my head as they go by thinking I may have just seen an 8 but then realize it is the S2000. Love the car just needed extra passenger seating for functionality... :D:

First thing I noticed when I purchased my Axial Flow Shift Kit was he offered a S2000 shift kit also.

Remember hearing a story of how there was little faith in improving the S2000 shifter... till it was tested. ;)

I think there is a mix of opinions on the Axial shortshifter - some owners are really happy with whilst a few owners are not happy with the extra vibrations involved which seems to come "hand in hand" with the better "feel" you get with it. I've nearly bought one myself, but hesitated due to a few mixed reports.

RP when you get done with 7-stock I need to get in contact with you
I have come up with an idea that I perceive may work to control a higher pressure version of your AFSC. :rock:

There is a patent search on going right now to see if anyone else is using something similar in a similar way. Initial very broad searches have turned up something similar in industry for larger axial flow compressors but nothing as it pertains to the automotive industry.


Advantages of a higher boost profile in the lower RMP ranges while controlling upper rpm pressures to prevent over pressurizing the engine. :crazy:

Then device was hinted at over in the S2ki AFSC forum by a fellow individual that is now handling my patent searches. :slap: It was hinted at before we decided to pursue the possible device. So he may have let the cat out of the bag to early. :nono:

While I haven't seen it the only thing I can think of would be to bleed air out from an earlier stage and send the rest into a closed loop mode so you could vary pressure based on number of stages currently in use. I'm not even sure it could work but is it something along those lines?

nope :)
good idea, did think of that; However I think that would that not require a major redesign of the compressor housing to allow those flow paths/controls.


My idea allows a single high pressure AFSC to be applied to a multiple number of vehicles regardless of max RPM and displacement (assuming the displacement of the engine is not so large the CFM @ specific pressure is larger then the AFSC can supply).

It also allows the compressor to be more efficient(mechanically; less power form the crank at a given pressure) when running pressures below its maximum out put as compared to a lower max boost compressor running at the same output pressure.

I am designing this device to keep along the lines of what RP has already created to keep prototyping times and cost down.

Main thing I am going to need is a compressor that is capable of producing 13psi at a max RPM 8K on my test mule (S2000). While I could prove the design on a lower max psi AFSC I want to make sure the device has enough fidelity and response time to maintain 8psi during VTEC Switch over. Desired boost profile based in a 13psi uncontrolled ASFC at 8K engine rpm would be at 100% throttle 7.5psi at 2.5k rpm and 8 at 3krpm with the device keeping boost at 8 psi there and above. This in an attempt to directly compete with the Turbo applications for the S2000 with most of those systems reaching full boost (8psi) around 3 to 3200RPM with this system having no boost lag and the reliability of a supercharger.

The device would also be double fault tolerant to prevent any sort of over pressure during prototyping and this double failure protection would most likely carry over the final product if it does get into production.

and so fellow lover of 9,000 revs :ylsuper:

No problems mate - it's just that we dont always short shift at 9000 :p:

LOL!

Cheers,
Hymee.

Hurry up Seven Stock--I am going to die before this dang thing is available.
Might say to hell with it and just break out my old Cushman Motor Scooter.

Why does it have to be like a Christmas day surprise???

Come on RP, Just "spill the beans" and tell us everything.

While I haven't seen it the only thing I can think of would be to bleed air out from an earlier stage and send the rest into a closed loop mode so you could vary pressure based on number of stages currently in use. I'm not even sure it could work but is it something along those lines?

Thats basically how its usually done on larger units. When certain conditions are met blowoff lines open up somewhere around the middle stages and feed the air back into the early stages of the compressor - its used to greatly reduce compressor surges

Cant wait to see how SS9 turns out... I expect someone going to SS9 to have a laptop with a wireless connection with continuously updated pictures or a live feed :lol:

Many have waited long enough for this year, SCs, TCs, TUNING!... man... The 8s are gonna fly.

and just like the rx7, we are gonna see lots of whining over blown engines from people who need thier hood welded shut and can't resist the urge to tinker with what they don't understand..

Can anyone explain what is it about the AFSC that has you all so excited vs other types of SC or turbos ?

lightweight and compact

linear boost profile, which maintins ther characteristics of the stock power curve

it's different, and pretty damn cool.

it's efficient, much more so than existing solutions

I'm sure there are more.

I've been looking at the centrifugal supercharger & it provides linear boost also but I think it will heat the air more (perhaps) . So in that comparison the advantage would be that the need for an intercooler is gone - yes ?

it is to be released with out an intercooler as we are told.... should have lots of info after this weekend...

this is going to be a big weekend for fi rx8s.

beers :beer:

It is a more efficient compressor that is lighter weight and takes up less space. A centrifugal conpressor has to turn the airflow 90* when compressing it but an axial flow does not turn the flow at all. It compresses it as it moves through each stage from the intake back to the manifold so there is less power required from the engine to make the same boost and you can flow more air in a smaller unit. It is the same concept as most modern gas turbines use today. You can read up on jet engines to learn more about the concept.

The air still has to take a 90° turn when it leaves the compressor - not to mention all the other turns it makes to get into the motor. Any change in direction impinges on flow. However, all FI solutions have to deal with this to some degree.
Add to that the angle of the inlet - a jet engine takes air directly into the first compressor row, but the AX has a drive mechanism there, so It has to enter at an angle.

the efficiency is in the compressor blades and their orientation... not which way the air flows

True - in rating the eff of the compressor itself.
However, everything counts in the real world.

the efficiency is in the compressor blades and their orientation... not which way the air flows

That's what I was referring to. Agreed you still have an angle the airflow goes around on entry and when you go through the intake manifold there is some loss but the compression process does not take as much power from the engine and can flow more so you have less power drain and more flow than a comparable centrifugal compressor.
