as far as volume vs volume it depends on the size of the roots and its pulley. Centis do have great volume but not till almost redline, its like sticking a large turbo on a 1 cylinder engine, u really have to wind it up. The prochargers C1 is 1000 cfm's at about 24psi. where a eaton m62 5th gen is close to 800 cfm's with a 2.5 pulley <im taking a guess on the eaton m62 cfm's with a total of 20-21LB of boost>. It takes no rocket scientist to figure out that 2 identical cars, except one has a m62 and the other has a procharger c1 and differant tuning on both, will be fast. The one with the C1 will make more power, thats for sure. But the one with the eaton will accelerate faster and have a more broader and useable TQ and HP. A LSJ only needs a 2.5 pulley, 60LB injectors, tuning and slicks and he'll run a 12.6-12.8 <i forgot>. People choose turbo over supercharging for the top end. People choose supercharging over turbo charging for the instant boost. A centi doesnt offer the instant boost that a twinscrew and roots provide. and a centi doesnt have the topend that a turbo has.
what good is an increased volume of boost if u dont see 100% of it till about 1 second before you shift into the next gear?
