Thomas Knight Supercharger Kit, Eaton M90, 3000gt

[Goat Blower]

Nah, there's no cancelling of boost to run the supercharger. It's only parasitic drag on the crank that cancels some horsepower, not boost.

I just read last night that a regular old centrifugal supercharger can use up to 50 horsepower to run it on a big block Chebby. They also talked quite a bit about the drag from the supercharger pulling crank pulley's apart. They also can bend a supercharger mount that's not strong enough. They use two 3/4" aluminum plates to mount the supercharger. Interesting.

I think a nice pair of 13t’s or 15G’s would have done nicely. 14b’s probably would have been a bit excessive for the power range we were/are going for.
