Blown Alky Question
Just how high can you go in compression ratio when blowing an alky engine, and how much boost can it live with? I'm running a 496ci Brodix BB2X headed motor, at 14 to 1 comp, on alky, using a BLP 1150 Dominator. I'm looking at the Procharger F2 system.
I'm just looking at this for theory and giggles, but haven't been able to find any info on the limits of a supercharged alky system. And anything I have found has been roots style based. :arrow: -Tanner |
Boost is Boost no matter where it comes from, I run a blown SBC and it has 11 to 1 compression,after reading up on it the max is 12 to 1 this is on alcohol, Do your homework on it ,thats all I got to say.

to clear it up a little more 12 to 1 is recommended as static compression ( before boost) on blown alcohol...NOT final... ..final is way up on the ladder... there are charts to track a final. Brian |
Thanks, it's just something I was wondering about.

11.2 - 11.7 to 1 static compression is where you need to be for a blown alcohol BBC.
