my opinoin is that a lower compression/boost motor will make better power ,to a point.....to low and they are sluggish for low and part throttle. to high and your tuning window gets REALLY SMALL.....top fuel cars are only like 7 to 1,and a bunch of boost.either way works but its more about the entire package........any engine that runs well is a well thought out package......dont get to caught up in the boost thing , its allways about air flow. boost numbers between 2 different engine packages mean nothing.....
