? Kenne Bell Blowzilla
I am thinking of getting a blowzilla for my car. My reason for wanting a roots over a centerfugial is this: I want to be able to remove the supercharger belt so I can run N/A. I hear centerfugial cant do that but roots can.
Is this truth?

It depends on your S/C and setup. Some centrifugals are driven by the serpentine belt, so there's not much you can do. Mine was like this. Others have a completely separate belt that drives it. So that's fairly easy to disconnect. But then if you did do that, you'd have somewhat of an air restriction.

There's really no point to adding a supercharger if you want to run NA sometimes. If that's the case, your best bet would be to run nitrous. You can spray whenever you like, plus the starting cost is cheaper.

To the OP: you probably already know this, but I think I should mention in just in case...
With a supercharger, no matter what type you get, it only gives you "boost" when you are at WOT (wide open throttle.) And even then, it's typically only after 2500 - 3000 RPM or so. So If you are driving around all week and put 500 miles on the car, but you NEVER floor it and get about 3000 RPM, then the car is going to be running exactly as if it were a N/A car anyway.
Superchargers are only in "boost" for a few seconds at a time. Using my old setup for example... even at the track when I was flooring it, I was on ly boosted for 11 - 12 seconds at most.
So if you want to be N/A, then keep it in Closed Loop and don't floor it. You don't have to disconnect the S/C to keep it out of boost. Or if you want to make it so that it doesn't go into boost even when at WOT, then just set it up so that your bypass valve stays open and doesn't shut.

Thats a very good point, you convinced me.
Next question, is there any hood clearance issues?
