Different locations and exhaust will give different boost levels, with the 3.4 that is rated for 9.5lbs. i show 8.8 lbs. on the dyno.
With the 3.2 pulley rated at 11.5 lbs. I show 10.4 lbs. on the dyno.
I have long tubes and O/R H-pipe, near sea-level but high humidity.
Yours can very well be different.
Yeah i know people say that when you add long tubes it lowers your boost . I have mac 1 3/4 headers, so i wonder how much boost i would actually receive with the 3.4" pulley. IF the 3.4" pulley gives me 8.8 lbs, then i think my decision would lean towards it. Im in houston so we also have near sea-level and high humidity, not as much as in louisiana though.
