Supercharger/Pulleys

99GT · 03-15-2000, 11:39 PM

Quick question... I have a Vortech S-trim, and was wondering if I can use underdrive pulleys as well. I don't think it's possible, but am not sure. Any help would be appreciated!

I'm pretty sure that you can't use underdrive pulleys with a supercharger. Don't they come with a new belt and pulley system that have to be used with the supercharger?

I'm pretty positive that you need the stock pulleys to run a supercharger. You could always call Vortech but the post I see hear always say to hold onto your stock pulleys if you're going to go to a S/C because you'll need them.

Thanks for the help! That's what I thought, because it did come with belts/pulleys, and the boost is regulated by the pulleys. Anyway, thanks a lot!
