Conclusion:

When placed into the formula:
HP = (flow in ml/min * # injector)/(10.5 * BSFC) I get:

(150 ml/min * 6)/(10.5 * .55) = 156 HP

Way too low for SC and much too low for Supercharged system.

Does anyone see any error in my procedure?
Is there any other thing I should check?
I have often wondered about the formula many have used in calculating HP based upon injector output on CIS systems. I think that formula may work very well for EFI, pulsed injectors.

These are Continuous Injection systems and deliver fuel 720* of the four-stroke cycle. I think that's where the error is and not in your measurements.
