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. 3/11/2013 8:20:43 AM |

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

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 3/11/2013 11:11:16 AM |

so is the car's name really "galaxie", a misspelled "galaxy"? 3/11/2013 12:39:51 PM |

from my limited and albeit outdated experience, peak cylinder pressure and total CFM were what mattered in terms of building for resilience and power.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. 3/11/2013 1:57:51 PM |
