Boost #s on a 2.3 whipple

[shofe10]

Installing my whipple this week and was wondering what boost Id get out of a the stock 3.5 whipple pulley and a 4# lower. Should I go ahead and get the 3.25 before I get the tune next week. Im in Fl so Ill be on 93 pump

gen2 whipple? a 3.5 upper and 4lb lower you will probably see around 18lbs

a 3.25 with a 4# lower and youd be nearing 20lbs or over ... i would push that with mine on 93... just my .02

If its a Gen 1 then you will see 17lbs.
