That's the thing, with the twin screw you are building power witht the rpms increasing, so you won't be running a full 12psi at idle or part throttle but it will be there on demand. Its more stream line power than the turbo or procharger as you are not waiting to bild the boost before it kicks in
What Ive read is that fundamentally, Roots-type (twin screw) and centrifugal superchargers affect power differently because of the differences in how they work. The twin-screw supercharger will give you more torque, more low- and mid-range grunt; the additional power will taper off at higher revs because the efficiency of the compressor drops off. Centrifugal superchargers have a very similar effect as turbochargers: efficiency - and thus added power - predominantly increases with revs. The centrifugal blower, you won't get much more power down low, but as you get up into the revs, you'll notice a bigger difference. I don't want alot of low mid-range power, I want higher rpm power. It also comes with an intercooler which is a must, so I wont have to have one custom made, and cetrifugal superchargers are more efficient. For these reasons, Im sold.
