You sure you have an 8 lower? I had a 4 lower makin that much, measure the pulley and see what size it is.

Example:
7.5 inches = stock
8.0 = 2lbs
8.25 = 3lbs
8.5 = 4lbs
8.75 = 5lbs
9.0 = 6lbs
9.50-9.75 = 8lbs (looks like a steering wheel)

Add approx .5 inches for every 2 lbs.

Upper pulley
2.93= stock
2.80= +1-2 Psi
2.75= +2-3 psi

All of these are estimated gains but should get close depending on the mfg. of the pulley

Don't make any differnence on the guage really ,I doubt you'd see a pound difference
stock airbox, stock TB, stock plenum, Dirty intercooler 4psi pulley made 13.5-14 psi even with a vaccuum leak

AEM Brute force,ported TB, and clean intercooler 4psi pulley made 13.5-14psi on same guage.

Biggest diference was when I adjusted the boost actuator, even on stock pulley I noticed a diff. on the guage probably due to the butterfly seating better and sealing up the leak by.

I think the reason that when people install all that stuff they see a boost diff. is because they adjust the actuator when they install a plenum or blower. I may be wrong, but all that stuff including a SC port just adds flow and efficiency not pressure.(those two things do add HP though)

Also I have added a 2.75 upper pulley to my 5lb lower pulley, before upper I would see 8 psi and then it would climb to 14.5-15 psi on the same guage. After the upper I see an instant 10 psi then it climbs to 16.5-17 psi. I only see this in a 3rd gear pull. On 1st and 2nd i see it max at 14psi before shift change.

Careful what you wish for with the more boost thing.

[SVENSONJR]

NOW I DONT HAVE ANY CONVERTORS SO IM NOT GOING TO SHOW AS MUCH BOOST. I FORGOT ABOUT THAT

Don't push the actuator down too much, you'll get into boost much quicker. You'll be at half throttle and be seeing a few pounds of boost.
