Ok... so say your engine has a VE of ~80%

Does that mean the first ~3 psi doesn't actually effect the calculated compression ratio... since it's just compensating for the engines in-ability to fill up the actual displacement of the engine?

still trying to settle on CR between 8 & 9.5 psi.

hate to show my lack of knowledge, but, just build for more boost.


real response ... "Hey, Ray, you reading this?"

well... 12-14 psi will give me end of the world kind of power so i don't need to build for too crazy (deep into 4 digits)

20+ psi and i'm approaching

from my limited and albeit outdated experience, peak cylinder pressure and total CFM were what mattered in terms of building for resilience and power. that said, I would opt for a higher compression ratio with more usable power since the car will be on the street most of the time. less wear on the turbo(s) as well.
