RE: Roots Type Supercharger
Thanks for your replies guys.
I stand corrected. It is not a power valve. It is an exhaust cutoff valve.
I did think about a barrel type valve like is in a rotary carb. I still have that design. That is similar to a butterfly valve. Your other point brings a new question. From looking at my design, can you suggest a drive ratio to accomplish 4 to 6 psi of boost. It is drawn with a 2 to 1 ratio for reference only. I think that will be a bit much but am not sure.
