Thread: Blower boost? + Engine dyno guessing?

Tweet

Hello.
Im wanting to see if anyone wants to take a stab at my horsepower n tourque numbers for my blown sbc.
350, 030 over=355ci
Steel crank n rods
Speed pro blower pistons = 8.1 comp ratio
465-488 X 270-280 - 224@50 and 114 lobe seperation cam
msd ignition
Weiand 6-71 blower
2 Edelbrock 500cfm carbs
Edelbrock performer rpm heads W/2.02 X 1.60 valves 170cc runners
Running 9lbs of boost.

Next.
Im running 8.1 comp ratio and my pulleys now are for 11-12 lbs of boost. Think even with my Alluminum heads that the boost will be to hi for pump gas? Thats why Im planning on 9lbs. Tnx, Hg
