Just ordered my kit from Jason at the RX-8 Store. PF Supercars will be doing the install and tuning. Will post pics once I get her up and running. Thanx to Jason at the RX-8 Store for a quick response! I will send you a map when I am done!

Way-to-go-bro! Let us know all the details and the differences to stock once its up and running.

I look forward to hearing details on tuning and performance from this first round if turbo kits. Interested to know what it does with our power band.

Congrats, can't wait to see how it turns out.

oooooooooooooooooooo anouther person i am sooo jealous of...congrats...can't wait to hear how it goes and how much more ZOOM it adds:D

trophymaker

Congrats man, the era of FI 8s is beginning.

RotorGeek

Congrats man. How much are they charging to do the install?

Gambit

congratulations...cheer on the delivery service to get it sooner!!

philodox

Congrats! Welcome to the club... FI club that is.. hehe

davefzr

Rub it in thankx

There is now a subset club in RX8 club haha

Omicron

Mark my words, it's only a matter of time till there is a dozen or so FI kits on the market...

punishr

Allright, I'm marking them........J/K!!!!!!!!

I think I will wait for the SSR kit or the PTP kit to come out before I jump into the FI club....

Then again, Hymee's supercharger kit is looking pretty damn good too!!!!!!!

ranger4277

SSR/SFR has come out.

punishr

SSR claims that the pricing from them will be cheeper than from SFR, and SSR also claims that they are tweeking the tuning and getting around 335whp and will post dyno sheets on their SSR-ENGINEERING website.

Fanman

If they get 335 hp that would be phenomenal. That is like 150-160 whp more than a stock RX8, almost double the hp. IF it is reliable. That is the big question with the Renesis & this massive of a hp increase.

When I was considering the nitrous install on my 8 one of the axioms I had counted on was the idea that most factory cars are capable of a 50% increase in h.p.(at the fly) with very little affect to the reliability of the engine. If that is the case we shouldn't be too surprised to find numbers like 330 h.p. as a starting point in the modding process. Whether through 7 pounds of boost, a 100 h.p. nitrous kit, or a combination thereof I think the RX-8 will show itself to be very responsive to such mods and we will have some very fast and quick cars when we hit our performance plateau.

Took the words right out of my mouth.....
I definately believe that this car has a lot more potential than most people realize or want to think. I think that we are just scratching the surface right now, and I can't wait to see what the near future will bring us.

Fanman

But in talking about the potential of this engine not as much in putting out power but in terms of reliability are we limited ? If we could strap a big turbo on it, or turn the boost up to 12 psi but the engine will only last 6,000 miles who will do that ? Wasn't that the problem with the RX7's. You could get insane amounts of hp out of them but the question wasn't if it would break, but when. With the Renesis will have have to tear apart the engine & throw in new apex seals if we want 300+ hp ? I'm all for more hp, but I guess Charles is in new territory, and so is SSR/SFR in 300+ hp. I'm just looking for more hp but still want the reliability to be almost on the level of a stock car. I know, isn't that what everybody wants ? But I guess if 5/6 psi is the max then I will stay there and not push the engine.

Snoochie

I think guitarjunkie would have a thing or two to say about rx7's not being reliable and lasting at high hp..

Fanman

I'm talking stock engine. I have seen some ridiculous RX7's but they all had beefed up apex seals, and more. Until people start introducing reinforced apex seals for the Renesis I'm just worried about how far we can go with this engine in stock form. I guess Charles is the first to really push the envelope.

punishr

Who said 5/6 psi is the max that the renesis can handle?

Fanman

That's just the level the Greddy & SFR/SSR turbo kits are set at (for Turbo) & some of the superchargers too. From seeing some of the problems that some of the SC kits have been getting at around the 385-300 hp range it is a bit troublesome (RB had some issues at around 285 hp that they were testing on one of their Renesis engines). Could be a fuel capacity issue, as there have been insights into hoe the returnless fuel system pretty much maxes out at around 60 hp +/- for the upcoming kits.

The sum total of my experience with the Renesis and mods has been that the engine can handle abuses that the previous models have not been able. So far I have accidentally revved it to 11,500 rpm(second gear at 80 mph), hit the fuel cut HARD while under nitrous boost(unexpectedly broke the tires loose near the top-end of second gear), subjected the Renesis to loads of detonation(during nitrous testing), and several strip-type passes on it. All this and the engine still runs great. I am in the high 12's for 1/4 mile times using a handful of bolt-on mods and a 55 shot. I would say the RX-8 is a "wolf in sheep's clothing" in stock trim and if the owner chooses can be a very competitive vehicle. Although not a drag car it can hold its own in the 1/4 mile and as far as wheelhop goes, with the pre-load removed it will hook up pretty good. On the matter of 285-300 h.p., I would venture to say that the fuel pump is up to the task but the factory injectors may not be. The odd thing is that the intake/MAF are said by a local tuning shop to be good up to 500 h.p. due to the size of the pipe and the type of MAF used. Coincidentally, the MAF is the same one used in the WRX/STi.

Good tuning, plenty of fuel, is all that is really needed .The only thing in question now is the compression ratio being a little higher. This might be a problem but we will find out soon .

Mazda's APEX seal is AWESOME. No need to change them IMO.
