It may have a lower drag at lower rpm, but from what I know of superchargers, you also experience a lag at lower rpm with centrifugal superchargers. With a Roots type or a twin screw type, you don't.mistermike said:Am I correct that the Vortech is a centrifugal blower, and as such should have much lower drag on the motor at low RPM?
This is true, but the Magnusson Roots blowers are actually made by Eaton, who worked out how to reduce the low RPM drag with a bypass valve.READYtoROCK said:It may have a lower drag at lower rpm, but from what I know of superchargers, you also experience a lag at lower rpm with centrifugal superchargers.

My thinking is unless you are running at the strip, low - mid range is where I want as much power as I can get. I can always find ways to hook up. On the street, you're not gonna need the extra power at the top end.mistermike said:My thinking was that the LS1 has plenty of grunt on the low end.
When I think about "top end power" I think of g forces at 90+ mph. A lot of street races are over by then.tbyrne said:Good low end power is something that you'll feel everyday without having to get the RPMs up. Top end power is good for a street race.
I agree with redneck.redneck said:What you can say about Roots vs centrifugal is that a Roots blower generates more or better low-end torque compared to an equivalent centrifugal. Therefore a Roots is probably a better choice for the street while a BIG centrifugal would be a good option for the strip.
