Alright guys I'm looking for a smaller pulley for my whipple. I have a 03 silverado ss with the 2.3l whipple and currently running a 4in pulley. I have already contacted whipple but they informed me that they no longer produce pulleys for my setup anymore so if anybody has one and is looking to get rid of it send me a pm. Thanks

Thats weird i just ordered a pulley from them, do you have one or two belt system, and do you have a dipstick or sight glass to check the oil level

Not sure who i talked to but i ordered a 3 5/8" pulley, i know they said that there were a bunch of sizes they were currently out of

Well I called them and ya they had a 3 5/8 pulley but I currently run a 4in and the 3 5/8 pulley will only give me one more pound of boost and I was looking for atleast a 3 1/2 in to get me @ 8lbs

A 3-5/8" pulley is 3/8" smaller than a 4" pulley, by Whipple's estimate and my experience, that should give you 3 more psi of boost.
