Turbocharged RX-8???

Hey guys..
Had anyone of you heard if there will be a turbocharged model for the RX-8? I heard that there will be one from the main factory still I haven't gotten any info about it. If you know anything please let me know.

-- Thanks

As of right now Mazda is in development for a mazdaspeed version of the rx-8. Both infortunatly no turbo. I believe the compression is just to high for a turbo'd version & the intake system not situated for a turbo either

heard about a turbokit from msp

i chaged my exhaust from my rx-8 and it is a difrence,a small one but there is.i race my mazda here in romania and i am pleased.of course i want more power but for the moment there is no one who can make the electronics for this cars. i gain fron the exhaust about 10 hp but i chaged the whole sistem from back to the catalyctic converter.the dealer from mazda told me thea i will lose the warranty if i changed the catalyctic converter but but with those things down i will gain 25 hp so friends with the exhaust 10hp and the k&n typchoon air filter 9.5 hp there is aditional power.but i need more ,and i descoverd turbo for rx8 but the price is verry hight $6250.http://www.speedforceracing.com/index.php
so we can hope for some engine electronics.

Hi people. ¿does anybody know if there's a Greedy Turbo kit for the RX-8? I just purchased the car last month and I'd luv 2 install that kit (if available) with a blow-off valve. Word of advice: don't mess w/engine electronics unless REALLY necessary, first work on all "easy stuff" (electric, exhaust, suspension, air-filters, etc), you'll get surprised how much power you'll gain if you make a smart job.

Word of advice: dont bring up old threads.
Oh and another: you'd better break in that engine before you even think about adding boost.

Theres a turbocharged RX-8 on Modifiedmag. Just came out.

Its uses the 13B engine though and everything else that was done to the 8 is sick!

There are two Turbokits...

Here is a neat FYI :
Sunflower Mazda in Olathe KS (outside of Kansas City) has done a Prototype Procharger SuperCharge INtercooled one they have roadraced. ProCharger ATI is only a few miles away from them. The Sales Manager spoke to me about it. He said it was putting out like 400hp. He said by the nature of the Rotary engine configuration meshed with the Rotary Centrifigal Blower it made it very efficient. The Rotary lacks lowend an the blower helps a bit there too and comes on very hard at about 3k.

400hp????

:eek2:

400hp????

:eek2:

You got 240 to start with and with a few mods can go to 260. Add on the ProCharger, higher boost than stock and 140 extra ponies is easy on an engine that revs like 9000rpm. I would worry about blowing up the Supercharger at those R's

this is wheel hp or bhp

400BHP, cause 240 on an RX8 is stock power (ps Mazda actualy changed there figures because it made much less than advertised and the first batch of customers got money back for that :P )

I'd like to see the Mazdaspeed version of the rx8 with the 274bhp 2.3L MZR motor from the mazdaspeed 6. That car I would buy.

Its didn't make much less. It made 12 less. You seem to hate on the 8 alot man! I don't know what's up with that. As for the topic of this thread. I believe its NOT going to have a Turbo, but I believe it will have a Super Charger. Many companies are actually starting to make superchargers for the 8 because for some reason they work better on the Rotary Engine.

The owner of RX8club.com said he drove a Greddy Turbo and a Pettit Supercharged RX8 and the supercharger felt like it had way more power accross the whole RPM Band!

Heres what it looks like:

Its still in the testing stage but right now that have between 30-50HP to the wheels at 6-8psi.

yeah greddy make's one. the stock rx8 made 202 whp on the 6speed and 160-70 on the automatic. the greddy kit made 260whp at 5-6psi. even so it didn't make much difference at the track. took only 0.2-0.3 off the 1/4mile ets.

oh check out racingbeat they said that mazda have squeezed as much power out off the motor. exhaust you only gain about 2-3 and on some they have lost power. intake about the same.

maybe the stock exhaust is really good?

Yes, from the knowledge I have on my car. The Stock exhaust may not be the best sounding but its very good for the car. I think the only company that can actually prove a gain is Racing Beat. Others claim but never prove it. Racing Beats exhaust is just a little deeper than stock. Which I actually like! But I've see plenty of Turboed RX8's with the right tunings getting over 300HP to the wheels.

I know Greddy makes a turbo kit for the RX-8, but does anyone know of any other companies that have come out with a turbo kit for the RX-8.

There is the PTP kit, Mazsport has 4 kits making over 400whp, Petit Racing just released a supercharger for it producing 260whp.

What would be the best turbo kit to install on an RX-8? I know Mazsport makes a decent turbo kit for the RX-8 which makes around 400 wheel horse with the stock motor.

you know that cause i said it.....and mazsport would be the best to go with, but they are most expensive, but that is what you get for having the turbo kit reliable and fast. The greddy kit has blown alot of motors and even though it costs less, the problems it causes makes you spend more than the mazsport kit.

I have the greddy kit on mine and I dont have alot of problems. The kit comes with really bad tuning so the first thing you need to do is get a wideband sensor and adjust fuel for boost and ignition timing. The stock injectors can handle constant 5.6 pounds of boost to redline with no problem. If you tune for peak torque then it can go up to 15.4 pounds. After you do that theres's really not much else to do unless you plan on turning up the boost.

well good luck to you and you're motor for boosting that 15.6pounds

I dont push 15.6 psi, only 6.3 ish max. Plus, its not 15.6 to redline its 15.6 to peak torque which is 5.4k rpm, I really dont know. There is alot of math invovled in coming up with these numbers, I could show you if you want?

no it's alright, i've never heard or seen anyone, even at peak tq push 15.6 pounds, ive never seen them go past 12 cause it become dangerous even with careful tuning. thats why most people get a bigger turbo and run lower boost.

yea 15 psi is rediculous but it sure would be fun for a couple of minutes. But I bet with racing fuel its not out of the question.

I think the reasoning for using a supercharger over a turbocharger is less likely of a boost spike to occur while the vehicle is being driven. Every one who has done some research on rotaries know that if boost spikes causing a possible lean mixture can say goodbye to the apex seals. The supercharger delivers a more controlled level of boost than a turbocharger, eventhough the supercharger does cause some parasitic draw on the motor. Also, a supercharger does not create as much heat as a turbocharger does thus can be used with out an air to air intercooler for less boost loss.
