Dan,

Barrett measured my hp on exactly the same engine at 2700 rpm on a dyno at 329 hp. I think Munson made some form of a measurement at 2800.

Anyone have thoughts about how to calculate horsepower on a 10:1
compression IO-550.  Other than having it dyno'd, is there a way to
figure out how much HP I am generating.  How would I figure out what
75%, 80% etc is?  I know fuel flow is a reasonable way to estimate HP
but what would I use as a conversion factor.

I know this is pretty basic, but I am trying to set up my MVP 50 to
read out a realistic HP% number.
Yes it is a Performance Engine and no I don't believe their claim (an
stamp on the engine plate) of 370 HP.

Thanks
