Greddy RX-8 and Speed Mag ... issues
#26
Despite what the possibilities are in regards to traction, driver, etc..., this was a horrible comparison. Frankly, I think it's like putting a Miata up against an S2000 or worse. If you want to compare these cars for the prowess on the track, fine...but not with 1/4 and 0-60. They even stated in the article how the brakes that they installed sucked. I wasn't sure what to make of it.
If I only get .5 sec in 1/4 or the same in 0-60 for $4000....forget it. I could replace my clutch and get lightweight rims and get close to that.
And for those considering the cost of an 8000rpm clutch drop? We are measuring what is the best possible time...that's all. Whatever you have to do to get it is fine. Does that mean that we should do this with our cars? Probably not, unless you are willing to replace your clutch or tranny....but these are all selling points. I know I bought my 8 for the looks, handling, and rotary.... if this car did 0-60 in 7.5 seconds...would you buy it for 32k? To me, that would be a hard sell.

It does 100mph in 2 minutes if you decide to accelerate slowly.
It does not do 0-60 in 7.5, it may do the rolling start in 7.5. When we read CD and RT numbers, they are displaying the best they could get from it. That's like saying it doesn't do a 14.5 or 15 in the 1/4 mile because you have to start off at 5mph. Has anyone ever heard of doing the 1/4 starting at 5mph? What are we talking about here? DO the Evo and STi do 0-60 in less than 5 sec? or are we not suppose to measure acceleration performance by 0-60?
Am I missing something?

I read the article over the weekend. The RX-8 looks and reads more like a GReddy show car, which it is, than a street car. Disabling ABS, no modifications like a clutch or flywheel to the drivetrain, etc...
Still, some of the feedback was very complimentary. One editor picked it as his top pick, and another said that the 8 would be the car he would pick to modify given a choice of any of the three bone stock.

Greddy turbos on this board are pulling better numbers than this--1/4mi times around 14.1-14.3. It was a good read--what I got out of it is that not all modifications better the car i.e. brakes and suspension.

A Consideration
I have a question to pose.
Is the RX8 a dragster From my point of view the answer is no. It can be turned into one, but it is not a 1/4 mile car. If we really boost the power, install a drag clutch a 2 way LSD, improve the suspension and install say 15" wrinkles on the rear, then we would have a competitive dragster, if that is what we are looking for.
On the road track, the concern is not what the car can do 0-60ft or 0-1/4 mile, but how it goes through the corner into a straight and how quick it gets up to speed before the next corner, and how well it brakes.
It could be that everyone is putting too much emphasis on the drag strip potential and too little on the road track where I believe it is designed to excel.
With a little retuning, some forced induction, vented brakes, racing clutch etc., I feel that it would be real hard to out run an RX8 on the road track in the hands of someone trained to handle it.
On the road track horse power while important, is not nearly as important and being able to handle the corners, and how quick the car can get to speed starting from say 50 or 60 mph.
I guess it all depends on which type of performance one is looking for. I dare say, that a car that is drag strip ready would not stand a chance against the RX8 on the road track. Yes that drag ready car will do great for the first 1/4 mile, but after that, it would just be eating the dust of the RX8.
All a matter of perspective and of course what your objective is, just something to consider.

I think we are getting off track, although I understand what Dragonrider is saying.
What is the point in installing a turbo kit? Simply, more power. Why do we want more power? Typically, it translates into better acceleration and higher top end (if not limited). That being the case, in your quest for more power, would you pay ~$4000 for a Greddy turbo kit if all you could be was .5 second or less improvement? I would say no. You could get better improvement for much less....as I said with earlier with nitrous.
In terms of the numbers, I think that a turbo kit that performs like this one did on this Greddy RX8 is not worth the money, that's all.

What a lot of people have to realize as well as different tracks, different conditions will give you different results...drastically different results. If they ran a stock RX8 @ 15.1, then a Greddy turboed car at 14.3-14.4 that is entirely plausible. Just because an RX8 hit 14.5 for one of the acceleration tests of one magazine @ one track, doesn't mean it will run it at all the tracks. I live here in LA, and the closest track we have here is Palmdale. It also happens to have horrible traction, is about 2,500 ft. above sea level, and is out in the desert (hot). If somebody could run an stock RX8 here 14.5 sec. in the 1/4 mi. I would give them $500. Hell, even low 15's might be hard. My previous car was supposed to run low 13's in the 1/4 mi. (according to the magazines) but I could never get below 13.9's. Just goes to show you that different tracks @ different drivers have a big difference.

Ex- member.
First of all, the greddy kit is $3000 (not $4k).
The slow time for the turbo'd 8 may be the drivers but the obvious sign is the weight.
What was it listed at? 3400+ lbs? wow..That car has too much "show" stuff. mine came in at 2980lbs (3180 w/ me in it) Difference is 400+lbs. That's like having 2 "big" people in their backseat. I'm sure that'll slow any car down.
I ran a 14.0sec with a boost leak (only got 6psi for 1sec then down to 3psi for the rest). I've found the leak and will easily reach a mid-high 13sec 1/4mile.
