The SC set up is different to a turbo set up. The torque is linear as is the boost. Because the SC derives its power from the pulley and a function to its rotation therefore maximum PSI is only achieved at max revs. This unit will produce 13 - 14 PSI at 7,200 at maximum rotor speed. So for the better most time its only going to be around 10 PSI. The SC puts less torque strain on the engine and the pistons. After speaking and seeing several engine builders most have come to the conclusion to only lower the CR from 11:1
to 9.5 - 10.0 :1 If anything to add a bit of safety.
This SC set up will never go any higher unless i change the unit as i have it set at max revs already with 7200 rpm. so max will be 13 -14 psi .
