Boost will vary based on bolt ons and engine work... I had an 4.25 pulley and was supposed to be good for 8 lbs on a stock engine. I was only getting 3 lbs based on my mods. I am now running a 3.23 pulley getting 11 lbs.

Whats up? I had the Red Procharged Z28 down in Austin a while back. Came down from Waco. I talked with you briefly. This pulley made me 11lbs at 5800rpms. We only spun it that high because of belt slip. The crank pulley is from EPP, so its 7.65.
Understand that. Was just curious. I am changing pullies right now on my '02 Z28 and am well aware that the boost # Procharger told me this new pulley combo will make is just a ballpark. I am hoping that our collective best guess turns out to be pretty accurate... but it may not.
If it was the meet at FM620 and I-35, then I remember talking with you and looking at the car. I think that was the same night a group of Waco cars went down south with us to "Mexico".
