I need either a 3.5" or 3.75" pulley for my head unit. Who sells them and how much should I expect to pay. This is for a BD series head unit. I found one and a vendor that upgrades them.

Is this a Powerdyne supercharger? 928 motorsports makes pulleys. You won't make much boost with that size pulley.

I've been doing some research and just found out the LS1 Powerdyne uses a smooth pulley. I talked to them on the phone today and they were not real familiar with the LS set up. I guess they just need to know what size pulley to cut.

The standard F-body kit came with a 3.12" diameter smooth pulley. It will make about 5 psi if you use a manual belt tensioner. A 2.9" will put you around 7 psi but at the risk of belt slippage.

Thanks for the info, I've searching all over the internet for information on this kit. Trying to find pictures of an installed kit on an F-body is like trying to capture bigfoot. I've read so much stuff, my heads going to explode. Here's what I've kind of put together. People bought these kits and tried to turn the wick up and the internal belts blew so they got a bad name. There were also some slippage and bearing issues. I have my reasons for wanting to use this kit. My car has 14k miles, is bone stock and I don't keep stuff very long. My Chevelle is loud and obnoxious, I want to keep this quiet and will be happy with low boost levels the kit provides. That place in WI seems to be able to make the head units pretty reliable too.

Anyone have pics?
