Hey guys...how ya do'in?

I just had a question about big bore kit compression....what's the difference between 12.5:1 compression and 11:1? What makes it better or worse?...more power the higher the comp.? or lower the comp?


thanks!

The higher the compression, the higher the power. The higher the compression, the higher the octane needed to avoid pinging. The higher the compression, the higher the pressure in the cylinder. I've had to choose between the two and chose 11:1. The higher the compression , the more difficult your machine will be. Just my opinion.
