under driven pulley dealer

Are you looking to slow it down, speed it up, or just experiment? Does the manufacturer offer some different size top pulleys? I'd think I'd look there first.
I think a little experiment, I just got it out for a couple of test drives and it definetly has boost I have'nt figured out how much just yet and I do intend to figure that out before I do anything to aggressive. You, know I have just been looking online for makers of pulleys, I did'nt even think to check manufacturer. I did'nt think B@M was in business anymore. I'm not going to get one right now, I wont be driveing my car till this spring I'm just trying to get it all up and running again after the supercharger installation. But when I go to buy one I would just like to be able to find one.
