I am pretty sure it will fit. I'm leaning towards getting a 2.75 pulley and running a little more than 17 psi. PM me a price on the 3" though, I might change my mind.
My friend has 2 SVT Focus pumps that were used for 8k miles with a Whipple @ 19#s with no problem. He's going return and letting these go for 180 shipped, let me know. Thanks
