I thought you could only pulley-down to a certain size to reach required amounts of boost? Yeah, the Vette front jackshaft drive and its front inlet TB mounting lets you X2 OD it like you are saying... Nobody has told me that only 10 psi can be had--just assuming that from the truck TVS design and that fact that you one can only buy down to a 2.6 pulley?? And that would put you ~10 psi? Only guessing--but I bet you could have a smaller pulley made. How small of a pulley can you go and it still be feasible/reliable? With a smaller pulley--it would create higher internal blower temps--which older Maggies have been criticized before--but the new TVS systems are suppose to be more efficient and run cooler, but if temps get to high, Meth can be used to cool those down...Originally Posted by farmtruc
