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...

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.

Ajax

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.

mysql101

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..

shelleys_man_06

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

Razz1

The best you can do is 5 psi

All other experiments have failed.

rotarygod

Wrong on both accounts.

8inVegas

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?

shelleys_man_06

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.

Rxdriftingaction

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?

Rxdriftingaction

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.

bureau13

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/

Fanman

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.

reddragonmd

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

bureau13

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.

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.
