how much boost will I be making
Ok here is what I have 2.3 whipple on of a 416 stroker the pulley on the whipple will be 2.75
Crankshaft will have a 10% overdrive pulley
Nick William 105 tb
Arh 1 7/8
Cam specs are 224/236 .644/ .644 117 lsa
I'm just looking for a rough estimate
I'm estimating about 14-16 #of boost what do you guys think also how will the 10% over drive affect the other pulley driven items

I have a gauge for that

Well the stock truck pulley is like 7.55" so 10% OD is 8.3"
2.3L is 140ci, and blower pulley is 2.75"
So blower CFM at 6000rpm is (140/12^3)*6000*(8.3/2.75)=1468
Engine CFM at 6000rpm is around 650cfm
1468/650=2.25
2.25*14.7-14.7=18.5psi of boost
Very rough estimate...
OD pulley is fine....everything just spins 10% faster. The problem with pulleys is when you use UD pulleys.
