8.5 compression. We got all the valves and springs from livernois a while back. Contact them and they get a set for you.

Great numbers and a turbo(s) is the way to go for more HP for the track....turbos are more track able IMO than S/C's (T/S's in particular). Not saying that it is not possible to do great with a TS but you proved (case in point with your car) regarding the KB vs. the Twins that you get more HP per psi

That's a no brainer... No belt
When I buy my built motor, my whipple will be for sale..... And one big *** turbo will be under my hood...

you guys are going on about this twin turbo stuff when the fastest 3 valve S197 is powered by a centri (procharger).

I know the fastest '05 is Justin from JPC, ohh no is acutally a 88mm single turbo from modular depot, I am not trying to be the fastest '05. My goal is to run a 9'second one day and I think my set-up will allow me to do it. I was just posting the numbers of my set-up. Maybe you should change your whipple and run a Procharger + juice...lol

That is correct.

I'm very happy now that my motor is built and tuned properly.

470 hp/490 tq ~9.5 psi on street tires is plenty for driving around town. I'n looing forward to getting the two step, loading in 100 octane and making a few runs at 530 hp 550tq. That should be lots of fun.

Congrats on the numbers. Properly set up you car should be really close to 9's.

i have a centri not a whipple

MYGT500 - I agree that a large single turbo is more of a track set up. But I think a TT is a good street set up at low boost. Very little turbo lag and good top end.

Only problem IMO is cost.
