"fuel(lbs per hour)", "horsepower" and "A/F ratio"? Can you determine A/F ratio from the other 2 numbers?
Example= 550 HP, 215 lbs/hr. What would A/F ratio be?
Or is there a guideline for linking HP with lbs/hr?

it doesn't work that way .... lbs per hour is how efficence the engine is .... if you have 2 different engines that both make 500 horse tuned to ideal AFR for package and one engine uses less fuel it's because it has a better port and chamber package( to name a couple ) and uses less fuel to make the same power

X2, BSFC not as useful as A/F IMO

Has the engine already been dynoed or are those numbers guesstimates?
If you are shopping for Dyno time make sure there is A/F reading capability. JB
Every second counts

Engine has been dyno'ed. A/F device was not working....

that's why I wanted to see if there was a correlation with those other numbers. Apparently not.
