Ok, so I take 60 hp out of a 660 hp motor makes 600 then add 150 would make it now 750 w n/o so it will be like adding 90 h/p, I just wanted to make sure It did'nt blow the rings out. I've been told that for every 100 hp of n/o is raising your compression up 1 point. like mine now is 15.33 to 1 then with the 150 shot of n/o it would be 17 to 1 is this true.
Thanks Andy
