by orientation i meant successive stages where the pressure is raised in smaller steps by blades that are designed to raise that small step with the least amount of drag possible - thats where the design really differs from other compressors

in the gas turbine industry there are generally 2 setups for the burner arrangement on the discharge of the compressor section. One is a "can-annular" setup where the burners are located aound the discharge of the compressor and airflow is remained straight though to a turbine section... this is the air craft design. The other design is a "silo" design where the compressor discharge is directed 90 degrees up around the outside of a silo shell and then redirected 180 degrees back down the center of the silo and sent through the burners and then makes another 90 degree bend to the turbine section. It would seem the silo method would be very ineffecient, but when done correctly real world data says you lose practically nothing.

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 ?

I beg to differ. Centrifugal Superchargers have exponential boost curves which result in exponential power curves. Turbo-charges, BTW, are exhaust driven Centrifugal SC's.

show me an exponential power curve and i'll show you a 4 legged chicken .

A belt-driven centrifugal is exponential to the extreme.
A turbo, while centrifugal, is not limited by input RPM, so its delivery can be tailored to fit the desired boost profile.

OK - i'm not sure on the boost chart but dynos i've seen are almost an exact copy of the N/A chart (linear) but with double the power .
BTW - I can show you a 4 legged chicken :)

Here's a dyno chart showing a stock S2000 dyno with a centrifugal supercharged S2000 curve on top of it. Where's my 4 legged chicken?

Thats a linear curve with the SC - not exponential .
It may as well be. It's worthless compared to a turbo power curve.

Thats a linear curve with the SC - not exponential .


Here's the chicken anyway :mdrmed:

by definition it is exponential..

the derivative of a power vs rpm curve is the torque vs rpm curve. For the power curve to be linear, the torque curve needs to be a strainght line single value.

You can see the NA curve approximates a flat line (linear power), while the SC has a continually rising torque curve - which mathematically makes the power curve exponential

one more day and we'll all get to see this bad boy.... (wonder how much it's changed since I saw the prototype a few months back)

Hhmmm? Maybe if I sell my PS3 on eBay...

Just kidding ;)

OK - point taken .
Anyone want to predict what the power curve for the AFSC is going to look like ?
I'm guessing (yes its a guess so don't flame me) it will look similar to the centrifugal but with a little more power earlier.

Hhmmm? Maybe if I sell my PS3 on eBay...

Just kidding ;)
I would lol... I'd rather sell ps3 for much more than it's worth on ebay and wait a few months lol. What day is it going to be shown? or will it be on display the whole weekend? Someone take pictures and post ASAP if you're going please... wont be able to make it to SS9 :tear:

The AFSC is very close to being done, and he is just working out some tuning bugs.
The SC will come with a tool to reflash the stock ECU to RP's preset maps.
He did not give me any power or torque numbers, only that he is still tuning it, and the included flash will be 5hp or so less than what the AFSC is capable of, for reliability reasons.
It will cost $4,300
RP estimates that it will be done in a few months.


Im quoting RX8SaxMan, if Im breaking forum rules or something by posting that let me know and I'll delete. I just know that alot of people are extremely curious about the axialflow supercharger and want to know.

I actually never heard any details on it and I saw Richard.

EDIT: This is RG loged on as Brillo.

Yeah I just saw it. It was after I had just posted saying I hadn't seen it.

That is funny, I saw RG several times but we never discussed supercharging at all. Maybe he was still sweating off all that free beer he was getting on Fri night.
I missed the banquet due to some problems at home. I let them give away my tickets in the raffle. Therefore I have no idea what happened to him in the second round of drinking.

I'm just waiting for someone to come up with a picture of the polished blower we had mounted on a spare engine. I saw lots of people taking pics of it, where are you all?

Is the front strut tower bar still going to be included in the kit?

Damn it, I knew there was something I was meaning to build!
Of course it will be in the kit.

I have a picture of it.

fred, were you at sevenstock??

Yep. 3rd year and counting. This is my yearly ritual now. I was looking for you and Steve Kan who was also there but had no luck on either account. I'm still in California. I'm leaving in the morning.

we can do a late-night denny's coffe run and hang for a bit

I'm too tired. Brillo is already asleep. We went out with Jim Langer from Racing Beat for a while.

Really? Cool!

We are lucky to know some really good rotary people. We've been hanging out with Rick Engman, Francesco Ianetti, Paul Thomas from Mazmart, Carlos Lopez, Jim Langer, Scott from Mazsport and company, and many others. We've got pics in our blog thread. It's great knowing these people. Richard had to get back so he couldn't stay after the show unfortunately.

Richard's kit looks really cool. He had several blowers on the table to play with. I'll load up pics when I get home tonight,

Hey, will this supercharger be offered for 4 ports?

There was some talk of making modifications for it, but it was not clear if this would be done or not.

I looked at some upper intake manifolds very closely at Racing Beat and I still believe the kit will bolt right up to the 4 port . It'll just need a block off plate for the aux ports attached to the new manifold. Greddy supplies this with their turbo kits to effectively turn a 6 port into a 4 port. It should be pretty easy.

thats a spicy meatball!

hearing the price of this supercharger right after i had come from seeing the 8k pricetag on the mazsport turbo was...a relief haha...

it looked real good though. suprised me at how small it actually is.

Mazsport's turbo may be expensive but no other turbo kit comes with injectors, fuel system upgrades, etc... As far as turbo kits go, they have the one to own. End of story. As far as superchargers go, we're still waiting. Hurry up Richard!

I like the price of the Axial Flow Supercharger too.

I do hope they open up the tuning options a bit more.

Or Hymee.

I had a question on the bend from the compressor outlet to the intake manifold. The prototype on the car looked like it had a piece of hose connecting the two in a sharp 90 turn. The engine out of the car with the polished supercharger on it didn't have a connecting piece between the intake manifold and the compressor outlet. It seems like a piece of rubber hose to make the turn at that point would cause a bunch of backpressure and loss. Is there a solid wall connection piece for that turn that will maintain a smooth wall and cross section?

Richard, I read what you listed in RG's SS9 blog. Can we assume that for your SC that we won't need to independently upgrade the fuel delivery, or ignition?

I guess what I'm looking for is that for those of us that take our car to the track, is there any more prep work we would need to do to seamlessly integrate you kit? It looks to me like just a new clutch and upgraded radiator.

I would personally always upgrade fuel and ignition.

I would personally always upgrade fuel and ignition.

Well, my instincts say the same. An upgraded fuel pump would be fine, I'd think. But to change injectors - how would that interface with Richard's reflash? Same as with changing out coils, again how will those interface with his reflash?

As far as we can tell the fuel system is OK for street use. I understand that when called upon for constant duty (fuel pump) they can overheat and slow down. I have no personal experiance with this. The ignition is going fine but we have only 16,000 mi on the car and wait to see where and when problems surface. The clutch will go out depending on your driving style and how much track you do. I would wait until it gives signs of slipage then replace it with a street/strip clutch. Not a race clutch.

We live in So California and my AC is never off yet I haven't seen any signs of overheating or even increase in heat level over how it ran before SC. Track time will show you if and when bigger radiators are needed. Remember you don't run the track with the AC on and you can lock the fans in. Plus you should be running better gas on track days.

In that light we will offer a second reflash for track days usage. This tune will work with 98+ fuel and lock the fans on.

Changing the injectors will require some retuning of the flash. With 1.5+/- Pr the stock injectors work fine. Coils shouldn't change anything unless they are somehow more advanced or retarded. All this is against our stated objective of giving the customer a kit that he can bolt on and use as if the car came that way. Changing out componants one after the other compounds itself into expensive and unreliable installations.

There will always be someone who needs more and they know that it will cost them. Speed costs, how fast do you want to go?

Thanks Richard.

I realize my questions somewhat complicate the plug and play setup. But I'd rather know up front and make the changes where necessary and just be done with it. If for my purposes, the ignition and fuel system must be upgraded because the car sees more than daily driving, than so be it. It's something I will have to pay for.

I just don't want to get to a track weekend, and find out that I need an upgraded pump/injectors, or upgraded coils, when it is too late and the weekend is now a wash.

there really isn't much of a point in changing the injectors unless you are using more fuel then they can provide - and you won't reach that point with this kit they way its shipped

I'm seriously considering getting this kit (If RP will ship to NZ ) .
The peak HP figure looks OK for me but I really want to know whats happening lower down the rev range . What RPM does boost come in & at what PSI ?

As I have said before RP this is the kit that can actually save the renasis. It should give good power from the get go, fair cost, reliability along with some flexability. looks good and is in sync with the renasis tech if you will. Great job you old bastard!
RP, if people are in an area where ambient temps never get above 80F there will not be any temp problems on the track. My coolant temp doesnt go over 210F on the track , oil temps never over 230 IF the engine is not overdriven(you can always push things too far!) Even when ambient temps are 100f coolant temps on my car has never goten over 215F and oil temps over 240F while on the track at speed. I was a little more cautious in pushing her/keeping her at max rpm or close to it. I have always used the little trick to activate the fans with the a/c switch on the cool down lap/pitting. I think I would actually more concerned with stop and go driving and long distance driving--then stop and go stuff. If the ambient temps are high and people dont use the a/c the temps can get high. I can acutally see some people putting this mod on their car and not have full gauges working. I would also mandate 5W30 oil.
ok enough from me--now have to talk the wife into not having that breast augmentation--so i can get one of these!

There's no such thing as fake boobs! If you can touch them, they're real.

Anyway that the stock engine cover could be modified to fit?

Would this work with the racing beat ram air duct?

From my last conversation with Richard:

- Engine cover will not fit.

- he's putting in a new intake so you'll lose the Revi but not sure if the Air Duct will be able to reach the new intake.

No.
No.

Next is the 4cyl Hyundai Tiburon kit right? lol

About that RB intake duct...it works with the stock intake as well....do you (Richard) know yet where your intake will be getting its air supply? I'm having a hard time picturing it, from the pictures recently posted it looks like it would work (I realize that the intake will be different).

The ram air duct might work but the REVi won't.

I'm only talking about the ram air duct.

Also have to lose the underdrive pulleys.

isn't the outlet of a blower enough of a ram air duct?

I was wondering about that... so I'd want to take my agency power pulley off?

Only if you don't want your blower spinning slower.

why would it spin slower? and does it not come with its own pullies??sorry... noob... :sadwavey:

why would it spin slower? and does it not come with its own pullies??sorry... noob... :sadwavey:

it would spin slower becuase the supercharger runs off the A/C belt. And since the AP underdrive underdrives the A/C by 20% you get 20% less supercharger also.

Not including the underdrive is like taking 5 steps forward and 1 step back.

If nothing else but to fight water pump cavitation at high rpms.

Tried to talk the wife into just getting one breast done:)----didnt work:(

Too funny !

so to have the ap pullies still installed will hurt the performance but not buy a whole lot..~10whp? or more? sorry.. i have the ap pullies,i still have the stock ones somewhere, but would rather not have to change them out... its an easy job now, but still.. im really looking forward to the S/c

The pullies will affect the performance and tune of the car with the SC. If you want to keep the pullies you will have to do some other FI to keep the numbers.

There are other pulley sets out there that underdrive the water pump and alternator by replacing their pulley out. Then the main engine pulley would remain stock. The problem then would be the belt supplied would be too long and you would need to source one of the proper length.

Lose the underdrive pulleys guys with this setup guys--its that simple.

As long as the crank pulley stays the stock size, you'll be fine changing the rest out.

richard is doing a great job providing a complete kit that will provide the power you want in a safe manner... why does everyone have the need to "improve" upon it :scratchhe

On a similar note, the same could be argued for Mazda's effort on with the RX-8.

Who's trying to improve upon his kit? I think the thing is that some people have aftermarket pulley and wanted to know the effects of keeping those on and if they should replace it with stock. At least that's what I was wondering. I figured it would have a negative effect but I just wanted to check. Thanks to those who responded though.

likewise.. i have the pullies installed.. wasnt sure if i should uninstall them or not

maybe you all can bribe richard to produce a special pulley for the blower...

if you have read the thread he is quite fond of certain items :)

People, people the little hp the pulleys free up will be a mute point with this system
OD

Pulleys, the SC has nothing to do with the WP, Alt belt. You can do anything you want with those. The AC belt will run the SC as well so it has to maintain the stock size lower pulley. This works because the AC compressor is disengaged by the ECU at 66% throttle. That leaves the whole belt to drive the SC when you are calling on it to do work.

^oooooo i like the sound of that :)

RP some people have an underdrive pulley on the main drive. Thats the one we are speaking of. Or are you feeding directly off an a/c pulley without the sc belt touching the main drive one?
Bump for my question--does your strut brace have a master cylinder support brace on it?
Sending PM
Olddragger

Everything drives directly off of the main pulley so it matters to everything. The main pulley drives the blower too. Even if he did spin the supercahrger straight off of the a/c pulley, which he isn't, it still wouldn't change the fact that the a/c is turning slower due to a smaller main pulley. The short is that if anyone wants to use a supercahrger, they will need to use a stock main pulley. If they absolutely must use an underdrive main pulley, they must be willing to accept less boost on the blower. While it would be possible for Richard to make a smaller pulley for the blower to compensate, it's just easier to keep a stock main. Keep it simple. Sell the underdrive main.

I hope this has not already been asked.

How close to stock is the intake sound? Is it a lot more aggressive like most of the aftermarket intake kits or did you try and keep it quiet like RB did with the REVI?

This works because the AC compressor is disengaged by the ECU at 66% throttle.

Is this a stock RX8 feature or something you have put in the flash ?

It should also be added that if you have something like the UR kit which has 3 pulleys in the kit, keeping 2 and throwing out the main pulley is also a big no-no...

Very true they run off of ratios together.

Putting the stock main pulley on will overdrive the other pulleys like going to a higher gear on a ten speed the back sprocket goes smaller to turn the wheel at a faster speed (less distance to turn).

I am not sure if the puerto ricans are coming out with a compressor :bootyshak
:lol:

beer was kicking in on that post

If you have an underdrive main pully, you'll need to find a way to effectively overdrive the SC. Simply find, make, or have made, a pully that will restore the ratio that the AFE supplied pulley and OEM main pully have. Come on people, just because you're buying a kit doesn't exempt you from getting a little creative.

Will there be different ECU flashes for the AxialFlow supercharger? Since it appears they are going the flash route.

Will there be a more agressive ECU flash for a higher psi??? Maybe something pushing 8 to 9 PSI.

The AC kick out is standard thet do it stock.
The flash still controls the fuel and timing past the standard manifold pressure. It does not control the boost, that is controled by crank RPM and pulley ratio.
There will be an optional flash that one can use for track days when you are running 100 oct fuel. This is a track tune and keeps the fans on and the AC off. It allows for more timing and maybe leaner mixtures but I haven't really set that up yet.

As for an update, the flash is working in a car right now and being developed.
We are finishing up on the new stator tooling next week, we hope.
(Sometimes tooling needs to be built a few times 'till it's right)
And I still haven't gotten to the strut bar.
We are out of shifters and we need to run those real quick. So they get slid in about now.

Thxs for the update. please include master cylender brace with the stut bar
od

My understanding is that you guys are going conservative on the boost. Its appears there is a conservative setup and a track setup.

Will there be something in between? I mean a setup that would be in the 8 to 9 PSI range, as oppose to the 4 to 6 PSI range. A setup that would push the limit of performance for a daily driver street car.

I think he just answered that in his last post... that'd be controlled by the pulleys not the flashes

Yeah, I underdand the pulleys are controlling boost. I'm saying a setup with the pulleys and any ECU flashes for a higher boost. So far, there is just 2 options. Will there be anymore?

if you wan tdiffernt than what he offers you will to go some other avenue for tuning. he is not going to customize for each persons individual tastes/desires.

let him finish one flash and later he will probably work on another with a pulley for a little difference in $

my understanding of it is that the only way it increase boost is to add stages to the SC itself.

a few questions...

would you be able to run 2 chargers?

if so, what would work better, one after the other or side by side?

if a 5 stage SC puts out 7psi, does that mean an 8 stage SC will put out 11.20psi or is it a case of deminishing returns due to more work to compress the air?

if you were to run 2 chargers side by side, both at 7# flowing 600CFM at max rpm each, does that mean that the motor will be taking in 1200CFM assuming it can?

i know that the renesis hasnt been developed to the point where these situations can happen. im just trying to get a better idea of how this particular design works. sorry if theve been asked before

RP any though on using something like this instead of the gears to step up the rotational speed

http://www.rotrex.com
>mouse over “technology”
> click on “concept” (show a cross section of the step up design)
>click on “Design & Production” also under “technology” to see an animation of the system.

The only advantage I can see from this design over the gearing you use is a more efficient way of stepping up the speed from the pulley to the main shaft. (not looking at the compressor just the way to step up the rotational speed)

The losses associated with gears (friction/ friction induced heat/backlash/teeth wear/gear noise) are no longer a problem.

Apparently From what I could dig up on there “oil” the viscosity increases as it passes through the area where the bearing are just about to touch.


So if you are able to get the tolerances just right the fluid properties provide a very efficient medium to transfer the rotational mechanical energy between the casing, bearing and main shaft ;and at the same time prevent actual metal to metal contact reducing any noise and surface wear at the speed the bearing/rollers must turn.

Not really sure on how this would play with the so called patent on the “traction drive”
Could just call it a bearing drive. :spank:


Also found some other technology that may be applied to the AFSC at a later time to increase the lower rpm boost profile.

RP - we need the stats on the test mule. How many miles, MPG, tickets, etc... :)

If I get me home renovation done under budget - then maybe '07 I'll hook up with 'ya.

RP (everyone)

I would be willing to pay extra if something like this was also included in the AFSC kit (as an option maybe). This seems very nice and the fact that is touch screen and OPEN (meaning other applications can run on it) would be really cool.

Hmmm, I wonder if Hymee could put his sCanalizer into that thing.
Have you seen this Mark? It's a whole lot easier then carrying a laptop around.

If you actually watch the demo you can see realtime readings on several functions. It boots up in 10 secs, much better then any laptop running WinBlows. Also has 2 analog inputs for external sensors, plus data logging to SD memory cards.

I must say its not really that pretty but that can be fixed easily enough. The screen however looks fantastic and touch screen for input means no need for keyboard or mouse. Direct connection to OBDII interface means no dongle (interface converter). Its small size leaves plenty of places to mount the device.

Coming from an embedded background this thing is truely a good deal and its functions are something everyone here wants in their car. The fact that GPS and other applications can be downloaded and run from this allows for all kinds of possibilites.

You guys ask for a lot of stuff. Higher stages, more boost, digital outputs. Things that cost money and take time. I say just get it out and worry about that stuff later!

When a kit is about to come out, people give up their wish list. When the kit comes out, they see the price and suddenly complain it's too expensive and they want it more simple. You can't win as a forced induction manufacturer.

The enemy of good enough is perfection. You've got to draw the line so you can get a product out, get your customers hooked, and make enough money to put out the new version with all the new bells and whistles so your customers will come back for more.

The dasDAQ looks awesome... the 200MHz processor though may be a drawback in a GPS/Navigation program though (that is if you actually find something worthwhile that runs Linux)

after I got the new engine (coolant leak into the first rotor chamber) My Dealer asked when I was going to turbocharge or supercharge the car. I said I was going to wait till the warranty ran out and the service manager said why? you can put a turbo or supercharger on the car without voiding the warranty. Mazda would have to prove the supercharger or turbocharger caused the failure.

So RP, When am I going to Supercharge my car?

Especially since my Dealer says I can without voiding the warranty.

Really, I would like to know which dealership said that in WA? I think a lot of people are like you right now and are waiting off for the warranty to expire.

actually, TomTom is a 200MHz processor system running Linux... they don't sell that software though that i know of unforutnetly without their device, only the pocketPC software is sold seperately :mad:

All this about waiting for the warranty to run out is silly. A car is the most fun when it is new, not getting the most enjoyment from it then is a false economy.
What will fail that would have been dealer repaired? Baring you tuning a stupid tune into it your not likely to destroy the engine.
Like the dealer above said it would have to be SC related to be refused. And so what if it does, you still had fun and can rebuild the engine for a reasonable amount compared to piston engines.

The only real excuse you have is the CARB problem. That is something that we want to do and I can't tell you how long it will take but there is no reason it can't. Right now our car will pass everything but the visual test. If your state uses a sniffer test then your fine.

BTW, University Mazda gets the world dealer award for fine (and honest) service.

So just think about the years your taking off your own life by being upset everytime some econo box beats you up to freeway speed from the on ramp. And you feel embarased on Mazdas behalf. Give your heart a break and supercharge. I wonder if that could be a medical expense, thus tax deductable. :mdrmed:

All this about waiting for the warranty to run out is silly. A car is the most fun when it is new, not getting the most enjoyment from it then is a false economy.

I agree. If your engine is going to fail under boost, don't you think it would be more likely to do so after you've put 60k miles on it and then supercharge it? You might have to fight a little bit harder to get some stuff covered, but most warranty covered issues will be electrical or non-powertrain related anyway. A supercharger isn't going to void your warranty, only the stuff directly affected by it (engine and drivetrain).

That being said, I've been waiting so long for FI that my warranty is long gone, so somebody hurry up.

my warranty is out in less than a month.... mind you, the AFSC still isnt offically out yet, and the UK/ EU ECU issues have yet to be finalised.

I recently heard that the actual physical EU ECU unit isnt actually the same as the US one and that the pin connection etc might be diferent.

RP for Surgeon General! :rock: Great way of thinking :D:

I'm sold Richard. Had a great conversation with you at 7stock about the AFSC. Liked what I saw. Agree with the price. It is the right solution for the goals I set. Don't care about my warranty. Want to improve my health and stress levels. Where is my supercharger?! :rofl:

Need any local beta testers? :)

Just got back from the Dr's office.
I got mine! :rock:

Now where's that pick-up window?

lol

On a serious note, I'm thinking about getting the Rotary Performance (RP) Supercat midpipe.
I have the Mazdaspeed Dual Sport Exhaust.
I know not to buy an intake, since one will be included in the kit, but would it be beneficial to get the RP Supercat?

depends.... whats the mazdaspeed piping size? if its bigger then stock then yes. the supercat is 3" and the cat they use flow over 650CFM (i think thats what they told me).

an SCed rotary still benefits from a free flowing exhaust

ill look for it but i think ive seen a few posts where the cats are burning out on those units. you might wanna read up on it before you spend the money

I think Pettit has commented on this for their SC. I would think we would have similar issues with running boost of any sort and a cat.

Ghost: I remember hearing people complain that some of their RP supercats were going out in 10-20K miles!

I've put 30K on my RP Supercat and it's still going...knocks on wood...

depends.... whats the mazdaspeed piping size? if its bigger then stock then yes. the supercat is 3" and the cat they use flow over 650CFM (i think thats what they told me).

ill look for it but i think ive seen a few posts where the cats are burning out on those units. you might wanna read up on it before you spend the moneyWere they burning out in NA of FI cars? Wouldn't that limit us to a racing mid-pipe w/ no cat?

Off topic guys, but my RP cat is on a NA and I have the the second one they made.

Could not agree more . Many people spend half their life sitting around waiting for everything to be just right before they do something - what a waste !

they were on NA cars

florida does not have emition so if it is easer for you to put it out with out that and the flash could probably be also easer to do without that concern, plus some people in others states will probably take them also.

I have the RP super cat and the Hymee catback plus a resonator added. I don't have any reason to think it will fail but I only have about 2000 miles on it. We did have the exhaust off the other day and I looked inside, the cat looked new.

I also can't say for sure, but instinct says this one runs cooler then stock.
We did not add an extra hanger as some have done. Strange but it didn't rattle when first installed but after we had it off the other day it did???
This tells me there is a right and wrong way to install it. I'll let you know on this as soon as we figure out what it is.

Ghost: I remember hearing people complain that some of their RP supercats were going out in 10-20K miles!

Yes, I read thre or four people complaining about this.

I wonder if that's why they have the new design?

By the way Ceasar you hav eto have a CAT in most states.
I think think the SC will make the car run leaner and dump less fuel down the cat to cool it. It's been known that too much fuel is causing stock cats to burn out. The higher flow of RP will handle a SC no?

"The AFSC is very close to being done, and he is just working out some tuning bugs.
The SC will come with a tool to reflash the stock ECU to RP's preset maps.
He did not give me any power or torque numbers, only that he is still tuning it, and the included flash will be 5hp or so less than what the AFSC is capable of, for reliability reasons.
It will cost $4,300
RP estimates that it will be done in a few months."

I saw 275hp "easy" mentioned somewhere .

My state just checks for CEL's, only does a sniffer on older cars and there is no visual inspection. Are you getting any CEL's?

Once reflashed everything going on is normal to the computer.
If it shows a CEL then something is wrong.
It's just like it came from the factory that way, nothing will act strange.

So, if this is that simple of an install and tune, do we really need any gauges to monitor it at all?

I hope to be the 1st in Georgia with this kit. I trust ya and thats why I am a buying. I like sc over turbo (just to clarify that I trust SOME others also).
couple of questions:
1- does your reflash turn the fans on a little earier? If not, can that be done?
2- does the strut bar have a master cylinder brace ?
3- does the reflash coordinate with a high flow cat or does it work equally well with the stock cat?

grr- that brian herron was supposed to email me when that was ready- i didnt know they were showing it at sema. i want something just like this for my hymee scanalyser rather than lugging my laptop. thanks for the link . im going to start a new thread on it.

So I spent the last 3+ hours reading this post from page 1. After page 165ish I skipped to the end. Can someone give me a quick update on where Richard is with this? It was started in June 2004...wondering if a FI kit is out yet. Doesn't appear to be that way. BTW Richard, I like the work you did on your former blowers. Maybe you can throw something together for the upcoming Challenger. ;) It'd be nice to have a "recent, old-school muscle car" with a big blower coming out of the hood!

alrigher, here's the 30 second update:

- SC unit was offically debuted at SevenStock 9 two weeks ago and is getting close to being made available to the public.
-Richard mentioned a few weeks ago that he might be achieving 80-100 rwhp
- Kit will include a new intake. (no, aftermarket ones cannot be used with this kit)
- Will be very competitevely priced
- The system will most likely have your ecu reflashed with preprogrammed maps (2 maps available: street map and a map for those who autocross, etc)

Stay tuned to this thread for more updates.

A few that were at SS9 have put the target price at around $4300.

Great! Thanks for the update. As of now, my only other "high HP boost" option is a Greddy turbo which is offering a fairly small gain for a pretty high price. On a sidenote, anyone know about getting a third rotor installed for HP gain, or is that just a myth?

I know it's blasphemous, but I'm seriosly considering adding a couple of pistons to my rx8. 2 rotors and 2 pistons should give me the best of both worlds. You've got to figure out how to cut the pistons out at high rpm's since they won't go to 9k, but you get good low rpm torque.

(sorry I couldn't resist, but i did try.)

uh huh...I don't know if that was some sort of sarcastic shot at my post or not but the real important question in my mind is why you didn't answer my question. I was serious about the 3rd rotor deal. I had heard discussions on it a couple years ago in a non-street legal, drag-ready RX-8 using the Renesis w/ a 3rd rotor. Don't know if anyone had tried that, heard anything about it, or possibly had some links to the subject.

a 3 rotor is a possiblity. Check out the Major Horsepower section and see some of the work the guys out in Purto Rico are doing. (HUGE rotor heads out there doing GREAT work with 3 rotors)

The Renesis engine can be removed completely and replaced with a 20B 3 rotor.

how exactly would yougo about installing to pistons on a rotary? you would have to rebuild and fabricate the entire engine.. would you not? prolly be cheaper to just..you know.. buy the Sc?

I wonder if RP would consider taking deposits on his sc - maybe a few extra $ would hurry it up a bit .

Not much more work than "adding" a third rotor to a Renesis. Adding pistons was a joke.

no problem at all . I reakon you could jam an electric motor in there as well - that way you would have :
9k red line
low down torque
Environment freindly

wow !!!!!!

There is no 3 rotor Renesis.


And this is really getting off topic.

yea and i bet my questions will get overlooked
olddragger

I saw 275hp "easy" mentioned somewhere .

when i talked to them at seven stock they said it was going to be around 240 to the wheels. i have no doubt in my mind that after this kit will out preform the greddy in every category.

Don't feel unwelcome just because someone jokes around with you.

I suppose adding an AFSC could be considered installing 4 more rotors, if you can call a turbine stage a rotor.
-R.

It's just like it came from the factory that way, nothing will act strange.Perfect, nice to see someone doing things correctly. Is it worth doing RB's oil metering update with the AFSC?

If this gets me to about 275 at the wheels and everything functions like stock then it's probably next years upgrade. I already got approval from the wife as long as I stay under what I spent on wheels/tires ($6k). With the cost of the AFSC, gauges, and some custom paint work on the AFSC I should be right there.

Would it be possible to have the "street" and "track" modes of ECU flash switchable?

Absinthe - hallucinogenic from Wormwood. Been illegal in Europe until very recently, still illegal in the U.S. Been told by some European friends (one that is a medical doctor) that Swiss is the best to purchase. And that some are kind of moonshine themselves and that since Wormwood is actually poison, it is every dangerous to get.

Newsflash: Alcohol is poison also :)

everything is a poison. too much of anything will kill you.

Newsflash: Alcohol is poison also :)

Not a newsflash, the body can take very large amounts of alcohol as opposed to the wormwood derviative I was talking about. If I have to choose between one or the other, I'll take my chances with alcohol.

Besides the quote I use in my signiture, Dave Zeuchel used to say "Gasoline is for washing parts, Alcohol is for drinking and Nitro is for racing."
I have had that stuff "absinithe" but didn't like it. Thankfully, as I usually like anything that is bad for me.
Perhaps if I had known it was bad for me I'd have given it a second chance.
Maybe I'll try it again, which one you say is the most expensive? That's another bad habit I have. :hahano:

Maybe I'll try it again, which one you say is the most expensive? That's another bad habit I have. :hahano:
:ylsuper: I travel alot to europe (ITALY to be correct) and I can tell you that I have a bottle, (WELL 1/2 a bottle) of absinthe sitting in my freezer currently and the stuff taste like concentrated yager (sorry for the bad spelling). the one I have is the diluted version. crazy stuff though. drank it in italy did 2 shots of the strong concentrated version and then woke up the next day wondering how the hell I got home that night :Wconfused

Maybe it wasn't prepared correctly Richard

Did anyone mention Van Gogh yet?

Must be careful with that stuff from the sounds of it.


(My best man was going to give me a bottle of absinthe for a wedding gift :dunno: )

He mentioned that he still has it to try.

I've had the Van Gogh brand and another one too. I thought they were alright. One of my best friends had 7 different bottles of the stuff. Including 2 bottles of Thujone (The wormwood liquid) that you could add too your absinthe if you wanted.

http://en.wikipedia.org/wiki/Thujone - Says claims of it being dangerous (at the low doses found in Absinthe) and a hallucinogen are unfounded. Personally I had quite a bit of the stuff, with extra thujone and I didn't notice any "Special effects".

What a great thread. :)

Dude you have tattoos that glow in the dark!
I think that stuff had more of an effect than you think. :)

a compound derived from wormwood is also a very effective anti- malaria drug. like 90% effective.

You can't get malaria if you're dead! That's pretty effective. ;)

You visit Rotten.com? You are demented! (from one who knows) :)

:rofl:

I googled Van Gogh and that was one of the first hits.

Thought the same thing after I saw the source.

Sounds like we are all alcoholics here.

:scratchhe

Richard who is first in line for the AFS?

You drink the wormwood AFTER drinking the moonshine. The you will hug ANYBODY'S Momma and think she looks like a Ginko tree.
As for expense--how about some 100 yr old ginseng I have in a sealed container.(from my martial arts days/competition/networking)? I MAY trade it for an AFSC package--installed. Or a 50yr old TRUE Bonsei? (would not be able to get a complete system for that.)
As for a poison--even water can be harmful if used wrongly. And I drink too many damn diet cokes.
Olddragger

and so the AFSC thread goes off on another journey thru space.... 8)

Have to talk about something during the final developement!:)
Olddragger

Man! This supercharger sounds REALLY cool. I do hope a solution is found for us AT owners!!!

Ja, water can be very tricky, alot of people consume too much.

It's called drowning.:(

seriously drinking too much water can upset your electolyte balance causing lots of problems and even death.

If you had to pick one fluid to drink too much of, the safest one is definitely water.

Usually Americans don't drink enough and that causes health problems too.

well i dont know- too much gatorade for instance- is their such a thing? it perhaps could upset your stomach

water , on the other hand, kills http://www.washingtonpost.com/ac2/wp-dyn/A9158-2003Oct23?language=printer

You know a thread is off track when the moderators hijack it. :evil_laug

My theory- The anticipation is driving you all batty so you have to talk rubbish to keep sane.

well the day this SC comes out im going to miss this thread a lot. i dont know what i'm going to do with myself

Then probably spend quality time in defensive driving class.

Hi all,

I'm a long time lurker here and this is actually my first post. Richard, I'm planning on buying your kit but like most people I want to squeeze as much out of it as I can.

I was wondering if I installed an air-air intercooler if you thought it would cool things down enough to use 91 octane pump gas with the 100 octane map?

P.S. What is the expected perfomance gain of the 100 octane map vs, the 91 octane?

have you seen how it works ? No way to use an intercooler .

The reason there is no intercooler is due to the efficencies of the axial flow supercharger. The air doesn't heat up as much while being compressed. There for the intercooler is not necessary.

I wouldnt even think of trying to improve on this product. A very smart and talented man has spent a while developing this. And he was sober for the most part. Take it as it is to start with. After a little while THEN more options for the package may appear.
I still say that this is the package that will save the renasis for the everyday, fool with the car just every now and then, type of owner. This is the type of system that a MazdaSpeed RX8 should have. It will bring the power up to par with the market competition. And the next time I see Billy I am going to be driving one, let him see it, drive it and hope he will speak with his Uncle.
Heck, who knows maybe RP will be able to go to Italy a LOT:)

Wonder if Mazda are looking over RPs' shoulder :yesnod:

the whole point of the afs.. is to make the car more driveable, and fun... to give the car equal power to the cars ability....

it was not intended to be the tuning make more power do all..... i think mazsport will have that covered.. and pettit and hymee will fall some where in between...

richard is following the kiss system... that is what he has said he was doing...

i do not speak for him... but i have read every word of this thread...

i guess this is an outside the box update...

and to those in the know.. please correct me..


beers :beer:

Sort of off topic but I saw this program about the development of the first jet fighters and they were talking about how the ME 262 used an axial design and was superior to the British version which used a different design. Made me think of this supercharger.

Sort of off topic but I saw this program about the development of the first jet fighters and they were talking about how the ME 262 used an axial design and was superior to the British version which used a different design. Made me think of this supercharger. I saw the same show and was thinking about the same thing. The British design was a centrifugal design compressor. The main performance difference in the planes, according to the show, was aerodynamics. The size of the engine was larger than the German causing more drag. The performance figures for the two engines were similar.

richard
can the idle speed be increased to 1 K or does that "mess" with things too much. I know there is differant firing orders and such at the present idle program. Just wondering if yall have had that thought.

olddragger

We can't change anything in off boost conditions if we want to pass smog laws.
This way we can have exactly the same readings before and after the SC install.
Nothing is telling the engine there is a SC installed on it, it just has some kind of fan between the TB and the manifold. It changes nothing during the EPA cycle.
They have no spec for boosted conditions. :mdrmed:

I would say it's JUST some knd of fan.

It's a special one with lots of R&D and reliability.

Yeah. I think Richard Paul is just being modest.

cool and thanks-- I and the Ga Club await.
In almost process of getting Mazsport fuel pump upgrade. Then all I have to do is to get a little stronger clutch installed(mine is stock with 42K on it.), and the coils grounded,then I will be ready.
Smart on the Epa logic.
You really ought to try the downdraft tube mod for the oem oil neck to intake hose. It really does increase throttle response. Easy to do and if you dont like it just plug it back. I also took the acordian intake hose resonance chamber do hicky off. Doesnt do shit but sure looks cleaner and you can access your coils a LOT easier.
Oh and my wife isnt getting the boobs--we got a dog instead.

Sorry to hear about the dog. I assume you had no say in that one :dunno:
If I was to choose between the AFSC and boobs ASFC would win, but boobs would definitely win over a dog :yelrotflm

By the way what is this downdraft tube mod you are talking about?

A sporting dog I hope.

rp,

check pm.

For those of you who just have to have a version of the Axial flow SuperCharger today, and can adapt to the larger displacement (it's 19 inches long) original application:

http://tinyurl.com/y3uppk

a Latham original

Cheers

Mike, Just wondering (a) when, if ever, will this be done; and (b) what, if any, is the relationship or overlap or ???? between the Axial Flow project and Hymee's forced induction program?

Well things have improved in the last 50 years. The old unit like on Ebay will flow just about the same mass as the little one we have developed for the Rx8. It will have more max pressure, about 10psi due to it's 11 stage design but flow is close. Those old carbs had 15/16 throttle bores!!!!!!! To get over 100 cfm took 3in hg. 4in could get you 140!!!!!!!
They tip the scale at 33lbs without the carbs!!!

The one pictured can't do anything with the belt they have on it. They came with a wide flat belt and 5:1 or better ratio. The original design was for flathead Fords and used 2 carbs. The first unit was tested on a 272cu in Y-block Ford and reported in the June 1956 Hot Rod magazine. It was written by Racer Brown who tested at Edelbrock on their first Dyno. I have that supercharger in the garage at home. S/N 00001. I also have 2 brand new carbs for it.

Hymee and I are friends, plus he is the distributor for my products in Australia and Europe. We share information but as such it is confidential between the two of us. That is to the customers advantage as it speeds and advances development. So please don't ask what it is that we share because it is still privileged.
