What size is pulley that the whipple comes with and that's the boost. I know they make smaller pulleys but I haven't found any info on what the original size and boost is

Thanks in advanced

My Ford Racing Whipple came with a 4.0 inch. Depending on outside temperature, it would make around 9 psi. There are many different sizes available through aftermarket vendors and supposedly through Whipple.

Depends on when it was purchased new and whether it was an intercooled kit or not.
mine was purchased 03/2010 as the intercooled kit came with 3.125, supposed to do about 12lbs boost.

Same here. Mine was ordered in December 2011.

That's the answer I was looking for, thank you!!!

The stock Whipples came with anything from a 3.125 to a 4.0" pulley. I've seen 3.125, 3.25, 3.375, 3.50, and 3.625 myelf.

Are you sure? The 4.0 shouldn't make more than 6-7 psi max.

On a nice 30-40 deg. day I would make 9-9.5 psi. During the heat of the summer (90-100), 5 psi. A big difference depending on OAT.
