It's like guessing dog years.
3.5P - 3.0P = 5 lbs of boost @ 20hp per 1lb =100hp.
I have a 3.4/crusher. gained well over 100 hp & tq when going from a 4.0P to a 3.5P. But when I go to a 3.0P I don't expect to see that gain.
Why not just put and lsx motor in it and be done lol
Yep, another post that requires a thumbs down button LOL..................
Let me know when you get that function to work. Lol.
Just wondering what kind of rwhp gain I can expect going from 3.5” pulley to 3.0” pulley on the 2.9 Whipple Crusher?
Man thats going to be a lot of boost. I still have the smaller upper pullies and larger lower pullies from back when I ran a Whipple 2.3 but after running a 3.5 upper and stock lower with the 3.4 Crusher set up I saw 26# similar to what you see and that was enough for me. Haha. Nice build you have going on there.
Yea it will hit 28 and then settle out around 26. Usually run out of road really quick when you are doing that though. See 140's at the top of 4th. Haha.I thought you were at 28? What's a couple more PSI?
