OK...i'm sure everybody's seen this thread before at some point or another...but i'm lazy...haha and don't feel like looking it up...so neway...is there any proof of a mazdaspeed supercharger? and if so, when will it be out? how much boost? will everything come w/the kit? and how much will it run? any answers are much appreciated...

-Jim

No proof, See answer 1, 9PSI, thats why the call it a kit usually, less than the full mazdaspeed body kit and all the other mazdaspeed parts you can buy for the RX-8 ocmbined.

ha! very funny, 9psi wouldnt be too bad on this car actually.. That's about 144 horsepower at peak. And you know that it's gonna cost a fortune just cuz it's gonna say mazdaspeed and the fact that it'll maintain mazda warranty.

I was going to try to write a helpful post, but then I just didn't feel like looking up all that stuff up, either...Sorry 'bout that. You might try cross-posting this thread in the Discussion and all of the Regional Forums. Someone is bound to be enough of a sucker to do all that searching for you. Good luck. :D

dont hold your breath, the aftermarket cant even get FI to work

The only forced induction that is going to work on the RX-8 for now is the one in my head.

Mazdaspeed has a supercharged car. We saw it at sevenstock. It doesn't mean they'll produce it though.

right now the only news we know of is a convertable for 2006.

I don't think mazda speed will produce supercharge.. if they do so.. mazda will got some serious nasty business to deal with... na... it won't happen forget it.. if the charger can boost 9psi.. I might got almost 270 or 280 hp at wheel.. cuz guys u know new 13b engine got a bigger port then the old one..

Huh? How can you guarantee boosting a 1.3 liter engine with 9 psi can generate 270-280 rwhp?

The best you can do is 5 psi

All other experiments have failed.

Wrong on both accounts.

rotarygod, how much boost do you think is possible for our 8's? stuff you see in short term, and boost down the line, productionwise?

May I fill in rotarygod? :o

How much boost you can put on an engine is dependent on so many variables, such as displacement, altitude, strength of materials, etc. I wouldn't be surprised if in the near future, we would be seeing boost levels mirroring that of the 13B-REW. The key is the tuning. I should just make that my sig from now on. :)

dude.. our 13b is different with FD's 13B. a n/a engine boost up with turbo.. i really have no idea. 9psi with 270hp just a guess. but i think our 13b with 7psi is a good boost. not very high and no low. if i going to boost up my car with turbo.. i would like to keep the property of it.. a smooth car.. (turbo car never smooth I know) but.. just try to be barely smooth.. ha ha..

As was already stated, the key is in tuning. The problem is the RX-8 ecu is so finicky that tuning is that hard part. Since it is the single most important part, you are limited by how well you can control it. So far, the best option is Ric Shaw's ecu. It offers the most control. A true standalone would be best but then we get into the problems of not being able to control other functions of the vehicle or pass inspections. With enough time someone will develop an ecu that can be configured as a true standalone yet retain all of the other functions. Look at the Power FC 3rd gen RX-7 ecu upgrade as a good example. That ecu was available long after that car was no longer sold here. People still learned to tune very well before it though.

8 psi has already been successfully done with supercharging in testing on the Renesis. A number in psi is worthless though without knowing blower flow in cfm and the various forms of efficiency associated with various aspects of the supercharger. Boost in psi is just a number. You can't use it to solely judge how much power will be available at how much boost. You have to know far more than that. In a perfect world assuming 100% volumetric efficiency and no losses, you would exactly double your power for every 14.7 psi of boost you add. This isn't always true though because of so many other factors.

Folks, I would very much like to place a lightweight underdrive pulley onto my RX-8. I did this with my 300ZX and had very good results with no negative consequences at all. The pic of my Z and RX8 are in my virtual garage

The concern I have is that if MS comes out with electric supercharger, that underrunning the alternator might not allow the electric turbo to work 100%??? would you folks agree with that.....or if they come out with a belt driven Super charger then the underdrive pulley would underdrive that? Do you think my concerns are valid to delay purchasing an underdrive pulley set? :confused:

Rotarygod. wat about the reliability of the test u just mention about.I mean is tat the engine stable.(cuz u know most of our 8 is for daily drive) can u give some info about that supercharge ... but.. dude.. nice post.. I already learned something.

I think I heard Cameron Worth's Nordic Green was running 6PSI at Sevenstock, right guys? He said that was all he could push it without getting into tunning problems. It idled very smoothly and revved quite well.

Do you know what kind of engine management system he is using?

Sorry, I didn't find that out, but you could ask them at Pettit Racing I'm sure. http://www.pettitracing.com/

I was at Sevenstock, and asked the Petit Racing what they were running on their car, and they said 6 psi, then the rep said "nice & safe." Also when I was over at Racing Beat the next day I asked Jim Mederer about supercharging, and he told me that they had been testing it on the Renesis and it was no problem, that they had it running reliably on the engine. He told me about 285 hp.

I dont think well see anything in the near future that is a true reliable mass produced kit.

I wouldn't be so sure about that. For moderate boost levels like that, I have little doubt that kits will be available over the next year or so. As for reliability, how do you measure that? I'm sure it will have more issues than stock, but I'll bet when companies like Racing Beat come out with something, it will be as reliable as any other kit for other cars.

jds

racing beat already blew a motor or 2 supercharging. If 285 is reliable, that's about 350 crank horsepower. 120 horsepower gain isn't bad at all.

I'm looking for just a little bit more than that myself (300-320 wheel hp), so that'd make me very happy.

I'm thinking that might be 285 at the crank. Many of the SC units we are seeing are around 50 hp gain. That would put it at around 288 hp.

I would say Blitz might be the first true "mass" produced SC kit. You will get small outfits making their own units, but Blitz, Greddy, Apex, HKS, Vortech, Paxton, ATI, etc. are the companies I think of when you say mass produced. Of those I think only Blitz has a kit for us, though sunflower supposedly has an ATI unit they have on their RX8 car.

yep i think 285 is the crank. 240 whp i bet.

BAH! Need more power! Arr arr arr!

Racing Beat only has an engine dyno. Any numbers they quote are at the flywheel.

240 whp compared to the stock 170+whp? Come on, you'd probably take it if it was real.

Probably, but you gotta put things into perspective when you consider the cars I've driven and my enormous lust for rear end power :b

Not MazdaSpeed Japan!!!
Sound like the operation of MazdaSpeed US is not in conjunction with MazdaSpeed Japan.

I doubt MazdaSpeed Japan will ever talk about forced induction. As I post millions of time, the only player in Japan so far are:

Blitz - Compressor.
Phoenix power - using trust turbo.
Trust - similar development on turbo.
Knight sport - their own supercharger
RE Amemiya - Trust turbo in their AT 4 port Renesis.

I don't think I have missed any of them,.... :rolleyes:
No mention anywhere, in Videos, Option and Option 2 mag, RX-7 and RX-8 mag, RevSpeed in Japan EVER mention a Mazda made forced induction in Japan. So just stay cool please. Hope I clear THIS up once and FOR ALL!

Sorry, my serum crampy level is off the chart today :o

So just stay cool please. Hope I clear THIS up once and FOR ALL!



What's to clear up? They had one there. I don't care who made it, it was a Mazdaspeed car. Like I said, it doesn't mean they'll produce it.

Well if someone put an aftermarket forced induction in the car, although it has all the MazdaSpeed component available even in the MazdaSpeed JDM RX-8. It is still not a forced induction car from MazdaSpeed though.

Sounds like you put diamonds on a LV handbag and claim that LV made a diamond handbag. I rest my case :D

I have to clear up. There is no sight of the MazdaSpeed turbine available. Even so, Trust will be way ahead in the FI game in rotary car anyway

To me if MazdaSpeed US made a supercharged RX-8 will be equal as if Hymee put out a supercharge RX-8. Not a single difference to me what so ever. Anything that is not from Mazda Japan is AFTERMARKET. peroid.

I wonder what Hymee is up to?

Maybe Mazda will once again bring that Brilliant Blue FI car to SEMA for some more scrutiny. I plan on attending, and if it is there, I will get the whole story of its existence. This will be the fourth time that I know of it shows up in Vegas.

It wasn't just some car with a supercharger and a Mazdaspeed sticker sitting in the parking lot. It was in Mazda's showroom with their other cars. It is owned by them. The intercooler was way larger than they would ever use but regardless, it was their car.

why isn't anybody talking about better tuned engines for the 8 aside FI?
I remember reading somewhere that a mazda chief engineer said 'we can do anything with the renesis, increase displacement, increase number of rotors or turbocharge it'

What about a 3-rotor 8, like acosta motorsports made? I mean, ok, you don't have to reach extreme numbers (like the 900hp they claimed) but an engine like that, making 300-350hp, sounds pretty normal. and since rotaries don't survive turbos for long, why not follow the n/a way? longer engine life, insant throttle response with no lag...

Rotarygod any comments?

a 3 rotor renesis engine is impractical because of the port layout- specifically the siamesed exhaust ports. FI is a "simple" bolt on solution for people who already own the cars. increasing displacement, which by the way has been talked about on this forum many times at length, is not something the average owner with some hand tools can do himself. or even the above average owner. rotaries can and do survive turbos for long time periods with PROPER SIZING,TUNING AND COOLING. and modern turbos have nearly eliminated anything that could be considered lag. NA increases in power will come from porting polishing and engine management etc. not many people are as yet willing to crack their motors open for port work though and the ecu hasnt been an easy puppy to deal with.

maybe you're right. I just asked out of curiosity:rolleyes:
so 250-260hp is the most you can make, choosing the n/a way (from our euro 231hp cars), right?

just my personal opinion based on what ive learned about things since coming to this forum and talking with experts but here goes- i think there is probably 30% more power left to find in porting and polishing, tuning and intake/intake manifold/header/exhaust mods. maybe slightly more. so if you take a base number at the wheels which i believe is correct- 190whp and add 30% on top of that its 190+57= 247whp. i believe that is an achievable, hopefully even street/emissions legal number. and hopefully not just at the peak but usable power all across the rpm range. now add your FI on to that..... muhahahahahaha:) and get a really nice MS suspension.

I just saw a coverage in the Option mag about Phoneix power trust turbo dyno at 350ps at crank. Boost is 0.8kg/cm ... what is it in psi?

They said they need 2 intercoolers for it and still high in water temp.

You left out 1 thing that makes EVERYTHING faster.. the V-Tec sticker!! OMG!

ok.. just kidding..

That sounds about right on the engine.. FI on top of that would be sweet.

11.3 Psi

oh thx :p

Phoenix's Power's RX-8 is pretty much unfinished. At least they have the time and money to experiment. :(

Not MazdaSpeed Japan!!!
RE Amemiya - Trust turbo in their AT 4 port Renesis.

what? i had no idea anyone was even trying to develop a turbo for the AT

are there more details on this development? I thought the AT could not handle more HP, or was that just the 9,000 RPM redline that it couldn't handle?

There are videos in another thread that you can download... Let me try and find it.... It sounds pretty sweet..

Fo Shizzle Snizzle.... :)

Sorry.. cant find it.. Anyone?

that would be great, thanks my nizzle :D
a good 50 HP boost would be fine by me

They are getting there but a lot of cooling issue I heard. But does not sound like far off.

I hear some talk about a supercharged RX-8 comming out eventually....

anyone else know anything on this??...when it might come out?...if it really is gonna come out??...

Try a search -- there's been a lot of talk about it here, mostly speculation. Though there is one Mazda dealership that's working on one that they'll install and support. Here's a thread or two to get you started:

According to motortrend.com and speed magazine, Mazda IS working on a sc rx-8. Guess we'll have to pick up the magazine next month to find out for sure.
