How effective are these when used on a centrifugal supercharger? Typically, how much more boost can be gained, if any? Any opinions or theory of opperation on velocity rings would be appreciated.

We learned in fluid mechanics that the radius helps intake and out flow to a certain extent. If the radius is too long, the helping effect is lost and could hurt flow.

If the thing is actually engineered for the purpose of a supercharger intake, then it should make a few pounds of boost.

 

This is the only picture I could find.

 

FYI:

I picked up 4 HP at the wheels by installing a K&N stub stack on my carburetor.

The stub stack is designed to reduce turbulent currents as air enters
the carburetor. It seems the velocity ring may serve a similar purpose.

I'm thinking that device is installed on the mouth of the supercharger tube
inlet?

 

It needs to go right on the supercharger.

I am wanting to make one for my car, but I dont know about clearence between the block and the supercharger.

 

Has anyone out there ran one of these with a supercharger?
