just wondering if 12.2:1 compression ratio is too high for a supercharged gsr. if so what would be a good compression ratio?
 
:huh: Unless the motor is FULLY built from the bottom to the top, 12.2 is way to high. Is this a race only car?
I would probably run some where around 9:1 depending on how much boost.

Also you want to adjust your ignition timing and fuel pressure.

Peace, Theron <_<
 
its way too high. but 9:1 is way too low too.

stock, around 10:1 is perfect for a low boost application
