Once I fix up my new Bonneville'* supercharger, I would like to put on a smaller pulley. I'm aware it'* smaller than 3" in diameter, so what do you think I should get, and does anyone already have one for sale?

Typically a series 1 with that */c, a performance pulley would be 2.5"

Best product out there and a great price. Tell them John *. From bonnevilleclub sent ya

Before you do that, you MUST know your fuel pressure (post it here), and check your exhaust manifolds for cracks.

A full tune-up should be done first, and scan the car for KR before and after the pulley. It'* not just a plug-play situation. There are alot of dependencies.

We've had alot of Series 1 owners try smaller pulleys with bad results.

Thanks for the concern. I'm going to replace my stock exhaust manifold before I put in the new pulley. In fact, the pulley may be my last upgrade, but I'd like to buy one now to have it and feel good about the purchase. Tomorrow, I'm going to get a full tune-up, including an oil change, tire rotation & balancing, brake line bleeding and refilling, and later on in the day, I'm going to test my fuel pressure. I want to buy a fuel pressure sensor because I want to mod that as well in my car.

It'* quite insane, I think, but I want to try it. I may do pretty well if I have a new and improved manifold, right?
