Re: 12:1 COMPRESSION
I HATE having a high compression motor as my daily driver.
My shit would PING loud if I got anything remotely considered bad gas.
When I got my pistons though, I wasn't planning to make it a street motor.
To the OP, 11.5:1 has gotten many over 200whp VERY easily on 81/81.5mm motors. No need to do a tear down for almost nothing.
