2.3 Whipple with RR pulley.....How much boost?

[QuikHD]

Can anyone tell me how much boost a Whipple 2.3 puts out with a RR 2.95" or a 2.85" pulley?

I have a 3" pulley on it now, would a 2.95 make a noticable difference?

Thanks!

well on my old setup, i ran the 3.0/stock lower and made 16.5-17lbs, then added a 2.75 upper, and it made 19lbs.. but i think its better to add a lower pulley.. less chance for belt slip.. which became an issue for me... hope this helps.

stock lower? need more info bro! Most likely won't make that much difference over the 3.00.

Its a stock lower. I didnt mention it cause I never changed it. Not looking for a huge difference. On a BAP and 60lb injectors, I dont want to go too much higher on boost. Going to buy a new idler set (natural finish) and wanted a pulley for the whipple to match.

you'll gain a couple lbs from a 3.0 to a 2.85
