Back4More: More details and dyno graph at:

GPM: Here's what your data looks like. Got to love that centrifugal torque curve all flat and stretched out by the linear boost curve. What about your new data?

Re: How Much Boost????
598ci
Brodix 3x cnc
775 lift solid cam
Whipple quad rotor with moac inbtercooler
11# boost, 93 oct, 1260hp
15# boost 112oct, 1370hp
Dustin said I probably left 100hp on the table, A/F never got above 11.3, and Brake specific 6.5. maybe to small of carbs 1050's

Re: How Much Boost????
I'm still waiting to see some dyno sheets on those 1500 hp Whipple motors.
42MTI, wouldn't mind seeing your dyno sheet, it would be nice to compare, see how much more low end torque a Whipple makes, since we're running almost the same combo. Just curious, how many square inch is your intercooler, Procharger uses 648.

Re: How Much Boost????
TC, can you plot this one,12 rib blower belt started slipping and the power fell off, but the torque came in nice. I was thinking about trying a cog drive, and see what happens.

GPM: Here you go. New data on the dotted lines. I haven't figured out how to put the boost numbers on the right side of the graph but the highest boost from the first test was 16 psi so you can scale it from there.
What overall blower drive ratios are we looking at with these two tests?
