cheezehead Posted January 14, 2004 Report Share Posted January 14, 2004 I was just wondering what kind of numbers the compression would drop after engine porting? Quote Link to comment Share on other sites More sharing options...
boonman Posted January 14, 2004 Report Share Posted January 14, 2004 Depends. Static compression will fall when the exhaust port is set higher in the cylinder. And the rate of the fall, well, you would have to know the port height And dome size, and what not. There are too many variables to fit in there...
