That dyno sheet is indeed for a -1 headed procharger piece. All sourced form indys catalog. Russ and company are still there for now, and no they have not moved it from Indy YET, but that's coming.
Why would they not cut out the cancers that everyone complains about?!
I know I haven't spent a nickel with them and they are the reason why!
I've been to the Indy trade show with cash in hand and could not even get anyone to acknowledge me. I guess they tote all that hardware and those engines around in a Semi because they want to turn around and haul it home.
