Rule of thumb is approx 30 hp per boost pound.
Is that for centrifugals as well? I'm getting 12 psi intercooled, does that really equate to 360 hp? seems high to me.
I agree, that's high in my case as well. It is entirely based on the top-end of the motor. My heads are extremely restrictive, and boost is nothing but A MEASURE OF RESTRICTION. A 500 horse NA motor with good heads is going to respond to boost alot better than a stocker type combo.
11.48 @ 120 with a 1.80 60' 318, stock 1.88 heads, stock 904, Pump Gas, 13 lbs of boost.
9.94 @ 134, 318 on pump gas, 14 lbs w/ Eddies, transbrake 727, 3600 lbs, 3.54 gear and 28's.
