Speedy

Eddie has always called them and told them the sizes he needed when he has ordered mine. Give him a call or go straight to whipple for them. Also Eddie may have what you need right there at the shop. I know a few of mine are still there along with a large stack of other whipple pulleys.

Ill give him a call, thanks, I was gonna text you and see what pulley you where running on the 3.8's

Has always answered all my questions:

I'm running a 3 5/8 currently, which has me safely outside the limits of my fuel pumps and the closed loop cooling. I might get away with 3 1/2, but if went any smaller I would have to make some big changes.

https://whipplesuperchargers.com/i-2...pulley.html?q= got to this page and pull the drop down menu on size (sc pulley in diameter) in the drop down it has the sizes and this is a sizing reference guide *A general rule of thumb is every .125" of pulley change is .75psi of boost (increase/decrease). I have 2 that had my 4.0s at 7 lbs, i went to 9.25

Who changed my title it was suppose to read Whooples..........

yes that was not a misspelling lol .

OSD, what diameter are the ones you have ?

I believe 5.000, ill check when i get back to the house this eve.
