whipple pulley combos

[lightning666]

Just wondering what kind of boost you whipple guys are seeing. I should have my truck ready by this weekend, so I want to see if I should go ahead and order another pulley from LFP tomorrow.

Mods;
JLP stg 3 heads and cams
CAI
Kooks LTs, no cats, jdm SB
8# lower, and stock whipple 3.50 pulley

or if anybody has a good idea what kind of boost this will make.

Lightning Whipples don't come with 3.50 pullies. The largest they make is the 3.375. With my JDM motor, Stage 2 heads/cams, 8# lower and 3.25 upper, I see around 18psi.

I know where you can get a 3.8 and 4.0" pulley if you need one. ;-)

JDM longblock stage 3 heads/cams I'm seeing 16-17 psi with 3.375 upper/8# lower.
