My motor is 10.3:1...I run nothing but 112 fuel.I have the big 3 core sheetmetal cooler.I have the 7 inch crank pulley with a 3.85 on the blower,Im seeing 10# of boost as soon as I mash the pedal to the floor.I just had the head unit rebuilt and going to put on a 3.40 pulley,in your best guesstimate how much more boost will I see..Im hoping close to 14
