Scaled x .595 with a Lingenfelter 4" MAF and in an OS that's limited to 512G/sec what's the theoretical maximum Wheel Hp this combination "could" make?

I reckon about 1000 - 1100, Ian. More on E85

2 guesstimations to come up with this:

1. MAF goes about 830g/s @12200 hz.(meaning at .595 scaling, you dont run out of OS flow) 830 g/s = 110lb/min ~ 1100hp potential
and
2. 110lb/min = 6600lb/hr air, at 11.5:1 AFR (Gasoline) = 574lb/hr fuel & with BSFC of 0.55, hp = 574/.55 = 1040hp

Thanks Mark, and thanks for showing the Math :)

That would be at the crank?
