Thanks for the replies. I've tried to contact Whipple but got no response. I think they're only interested in selling big dollar kits for the popular engines at this point. This is going to be a custom one off deal on a oddball engine. There are places that refurbish these Whipple blowers and sell them for a whole lot less than new, and allow you to build your own kit. That's what I'm thinking I'll do. It will be intercooled with a water to air intercooler between the blower and the intake ports.

Boff, you say too big of a blower hurts low end. That doesn't matter on this engine. The only thing that matters is peak power. In this instance is there such a thing as too big?
