for the series 2 3800 with the stock 3.8" s/c pulley it can make anywhere from 5-7 psi of boost depending on the external temp and how well you engine is running. with a 3.4 pulley you will see 8-11 psi more if you have the right mods and stock exhaust.

My boost gauge reads 6 psi at wide open throttle.

my max psi so far is 7.1 at 4700rpm in 2nd gear...i could likely get more boost if i punched it from a stop but trying to watch for cops and press buttons on a palm pilot isnt easy(i dont have a boost gague in my car)
