I'm doing a custom install of a Thunderbird SC M90 supercharger on a 3.0L engine and need to underdrive it some to keep boost down to reasonable levels. I was wondering:
1. Do pulleys designed for the GM M90's fit on the Thunderbird M90? (offset won't be an issue because I'm fabricating the intake manifold)
2. If not, anyone know of a firm that does custom sized pulleys?
Thanks in advance,
Steve
