    to many things go into affecting what is best for your application.different pipes,porting and ignition timing all have an effect on it.but here is the basic concept.asphault and ice guys usually run a lower compression ratio than the dirt guys do 800 tripples can be 14.5 to 16:1 comp ratio for ice and asphault and the grass guys can be 1 or 2 points tighter than that for grass.Like i said alot of things that play into a final comp ratio to say exactly.This is where some guys will have 10's of thousands of dollars into a motor changing tuning aspects to find the sweet spot for their particular sled.Todd Guthrie dyna-tek performance
