the boost is variable... depends on atmospheric conditions and the rpm, throttle position and model... remember they have electronic blow off valves. It aint the old school turbo or supercharger that just increases boost semi-linearly until max RPMS! The verado supercharger is actually oversized to allow it to run high boost at low rpms (for acceleration) and then blows off excess boost at higher rpms where the boost isnt needed to make the rated power.
For example:
a 250 verado will run up to 14 psi in acceleration at peak torque, and taper down to 7-8 psi at WOT
now before you guys go applying the vast engine technology from the fast and furious crowd and disabling the blow off valve, remember that at high rpms making peak power, increasing boost will have consequences (higher intake temps, very high cylinder pressures, tons of knock, etc). The ricer crowd with blown car engines can get away with huge boost peaks because they dont continuously run their engines under high boost. I would love to see a riced out motor making 150+ HP/liter go on a dyno for 2-3 hours of WOT endurance. (hint, you might want to buy a couple of extra bags of kitty litter to absorb the oil in the dyno cell after the motor pops)
