Puke,
At the moment I have not tracked this car. I do Autocross and seem to be doing well in my class. The car is pretty much stock, minus the exhaust/intake, and tires.
I'm waiting to get my 15" stock rims back. I have them out on loan right now. But those will get some Khumo Victorracer tires. Which are a roadrace tire for autocrossing. And my koni shocks and springs.
Superchargers come in several stages 1,2,3. If/when I go forced induction. I'll have a stage 1 kit at 6-10lbs of boost. Which will put 175hp at the rear wheels. Which is plenty of tire smoking fun

Right now, lates test on the dyno jet was 119 hp 109lbs of torque @ 7200 rpm. Sock spec is 110 hp and 105 lbs. @ 7200 rpm. Not much real gain in the way of mod's.
BTW, the new RX-8's ar not dynoing very well. Very well under the factory spec's. Mazda's claiming its a safty break in and the cars will spec up to dyno. But Mazda will not let us know how many miles have to be on the car.
