Default Question for guys running 10-12psi (SC'd)

Hey,

Just wondering how much your ignition timing had to be retarded from stock to allow you to run around these boost levels without detonation? I know these values change with set-up etc, But would just like to know your PEAK ignition advance at wide open throttle.

Cheers

Dan

you will probably get different answers depending on octane rating.

-1 degree for every 2 psi is a pretty safe bet.

Feels good. Pulls well with the 3.2 combined with 4.30 gears. I am pleased. Honestly, I think I'm done. The car feels right. Now, I'm sure a ride in a turbo car might change my mind...that's why I refuse. hehe

For a track slut she runs well... thanks!
