I've been thinking of this since I saw the Vortech Blower To me it looks like a belt driven turbo. Which leads me to my question. Would it be possible to get a used turbo, modify it to be belt driven then mount it on a NA L28 with SU's. I was thinking of forcing the air into the stock intake air cleaner.

Would this work? Would there still be enough vacuum for the brakes and the vacuum advance? Could you put a blower on a L28 with flat top pistons and a N42 head or would the compression be to high?

Hmmmm???

I'm fairly certain that turbos are designed to work at MUCH higher rpm than a centrifugal blower, and driving a turbo via a belt would not produce any real boost.

Yeah turbos are designed to rotate at rpms around 150,000rpm and more, depending on the size of the turbo. (smaller ones generally spin the faster than larger turbos).

Anything is possible if you have the dollars to throw at it. Just impractical to modify a turbo to work as a supercharger, when you could just get a supercharger. and you wouldn't have to design and build gears to convert the rpm from an engine into the hundreds of thousands of rpm to drive the turbo.

If you want a turbo get a turbo. If you want a supercharger:
