I know is not recommended but are there any superchargers that you can run with underdrive pulleys. I really dont want to take them off when i put on a supercharger. Im leaning towards procharger btw. (I dont think i have the stock pulleys anyways)
it will definitely decrease the amount of boost made by the S/C. it takes less than an hour to swap, so may as well do it while you already have the rest of the front off and have a free shot to the pulleys. should take less than a half hour extra on top of the supercharger install.
i am sure you can get the stock pulleys from someone on the forums, or a place like newtakeoff.com. i know saleen changes the pulleys, and used to sell the take offs, but they do not have take off parts anymore, and direct people to NTO anyway.
