Freddy now has a 4.0L so the boost is probably higher that that.

with the mods i have done to the airbox i am hoping that my 4.0L makes at least 20 lbs of boost. if not then i will be putting a smaller pulley on it.

with that BIG intake you got and the 3.0" pulley, you got to be close to 30 lbs of boost now :eek

with the 3.5" pulley it was only making 20-21 lbs im going to put the 3 on it next but my motor is not stock either, heads have been ported cams are different so its hard to tell, I hope it will make at least 26-27lb but It probably wont, it would be nice to make over 1100 on boost alone! last time it made 933 at 21lbs of boost and that was without the new fuel system and the bigger injectors. this time...... have to wait and see when torrie gets here

A 4 inch pulley should make 19psi with the 4.0L Whipple. That would be with an otherwise stock engine though.
