W2 408 Dyno results today !

Looking at these two shots of run #4......
Just picking a line...... peak hp @6000......
Fuel flow is 233.3lbs/hr, bsfc for that line is .540.
233.3/.540= 432.0hp, uncorrected.

If the efficiency of the motor was producing bsfc numbers in the .470 range, the uncorrected HP would be more like 496hp, with that same 233.3lbs/hr(or it would be using way less fuel to produce the 432hp).

The thing I don’t think anyone mentioned yet is....... anything that causes the motor to make less power, makes the bsfc numbers look bad.
Even things that have nothing to do with the motor....... like poor air flow through the dyno cell.
