trust me, i am very excited about this kit. It'd be great to have 300whp, but if you do the math it doesnt add up...in a perfect system 1 bar will double the power (everything else constant, double the air, double the fuel), so .5 bar or ~7psi would be 50% more or 270whp (based on 180whp ), about 320 or so at the crank. Knock 20 off that because physics really only works in a dream world, and we have about 300bhp. A great generalization, but you get the idea.

but does the kit run more tha 7psi? Maybe...I didn't even think to ask! So who knows...

a few pics too at http://web.tampabay.rr.com/dv/

#78-81 are of the greddy kit, but there's alot of other pics in there, and a few of yours truly with some fine ladies :D

Is that a Red carbon fiber/kevlar wing, trunk, and rear bumper on that bronze rx8 in picture #70? If so, could you let me know who made it? Thanks epitrochoid.

Thanks for pic's, those are great.

Im lookingforward to the day a turbo Rx8 will slaughter an E46 M3. Hopefully that isnt too far away..

You're making the assumption that in its current form the car is tuned to get maximum power output and we know it's not. The tuning along with the turbo is going to make a sizeable difference in the power output of the car. If you can get 20-40 horsepower from tuning the air/fuel ratios without turbo, you're talking about 200 at the wheels rather than 180. Now add 7psi on top of that and you've got 300 at the wheels.

I don't think it's impossible to get 300 if not 320 at the wheels with proper tuning and 7psi of boost on this engine.

shaolin 11-07-2004 08:43 PM

^^^ Word. Tuning is key.

Japan8 11-07-2004 08:54 PM

Tuning wasn't seeing so much extra hp in Japan. Everyone (tuners) were giving numbers ~11ps for their a/f and ignition remapping... no e-manage here, they are going the RB route of flashing the ECU itself. Their stock whp numbers from chassis dynos were similar to the US spec cars as well. Trust/Greddy then added the turbo to this and was quoting hp figures under 300hp. They were giving like 265hp or so if memory serves.

So it may be possible that 300whp is their real figure, but based upon previous figures, it doesn't sound right.

punishr 11-07-2004 09:48 PM

I guess we will just have to wait and see then!!!!!!

Once again Shawrf1, keep us updated please.

mike_rx8 11-08-2004 01:48 AM

What do you think this greddy kit would put us in 1/4 mile?

rkostolni 11-08-2004 12:08 PM

With 7psi, I would expect low 13's, maybe high 12's with a decent driver.

epitrochoid 11-08-2004 01:49 PM

^^ Agreed

GReddy Turbo RX8 at SEMA 2004
 
1 Attachment(s)
Overboost.com has a pic and a few comments on the GReddy turbo RX8 featured at the SEMA show this year, stating that it will have the turbo kit available to the public in January and that will produce a little over 300 RWHP at 7 lbs of boost. Sounds great if it's true, time will tell. Also not sure about there new body kit, the front end with those big lights seems a little overdone IMHO.

tommy12g 11-08-2004 03:08 PM

We'll see....(won't get excited until something finally comes out!!) ....enough anticipation and lets downs.

VelociRedBeast 11-08-2004 03:11 PM

I like the BodyKit

BOOSTD 7 11-08-2004 03:36 PM

That's the RE-A bodykit ... I like it too. I would post my pics of the car (I took a LOT), but I lost my media card and all my pictures from the second day of SEMA :(

My take on the GReddy kit - they don't have their engine management worked out. It's the same kit that RE-A is using on their car, and the same kit that they've had running around for awhile in Japan. BUT, the US ecu protocol is different, and the e-Manage has fits with it. I asked them at the booth, and their US car only has about 200 miles on it with the kit. So I anticipate delays due to problems with the e-Manage on the US version, but I hope I'm wrong. I'll be in So Cal mid-December, and have a date to drive the US turbo'd car. By then, we'll know for sure whether their late Dec/early Jan release date can be met.

SimplexEffect 11-08-2004 03:46 PM

Well it is an RX8 to supposedly have 300 rwhp... I too dont like the lights that much but hey its a rx8 with a turbo.... No way in hell that i would not drive it :)

I would have to agree with you on that one :D

M-ster 11-08-2004 04:08 PM

I have always like the RE kit, and so far I've only seen it in white, til just now.
Man..., the tit grey looks gorgeous with this kit! I'm liking it even more now!

KingCobra 11-08-2004 04:18 PM

Anyone have more pics of this kit, I would like to see it from some other angles or in other colors to get a better feel for it.

XDEEDUBBX 11-08-2004 05:32 PM

i like the version without the BooBy Lights...

davefzr 11-08-2004 05:41 PM

Life is good huh.... :)

Geez.. Your doing what we only dream about.. I think we are in the wrong profession..... haha..

First the Pettit car and now Greddy.. Is there no end to this.. I hope not for the sake of the readers of RX Tuner :) Do you plan on reporting your findings anytime soon on both of these cars?

Awesome..

I'm not much into body kits- but that's not too bad

as for the kit- I wouldn't want to be the guinea pig (not that I could afford to be) but it's definately interesting:)

^^^ I emailed them about this kit and notified them of my concern that the kit may not come out.
