Should I lower compression?

pwcracer · May 9, 2005

I am replacing the head gasket in on my car and switching over to a set of ported GT40's at the same time. Due to the supercharger, would it make sense to go with a thicker compressed gasket to try and lower the compression ratio? I was thinking something around .050... I also have lame stamped steal rockers, does it make sense to swtich to rollers with a stock cam?

I'm not a power adder guy, but you will make more power WITH compression and boost than low compression with boost IF the tune is on and detonation is avoided. If you don't plan to turn the boost way up and the compression won't be much higher than 9.2:1 then I'd leave it alone. Running thicker head gaskets have a negative effect on quwench from what I've heard, but you'd have to chekc the power adders sections for more info on that.
