Hi Paul, Doug -

Normally, I'm just a passive reader, but on this I have to do more than
just agree to your comments.

A long time ago while researching engines, I learned that one gallon of
gasoline burned per hour can produce 15 usable horsepower [That is .4 BSFC.
See the enclosed chart from Fayette Taylor "The Internal Combustion Engine
Theory and Practice which is the bible of the internal combustion engine.
IMHO it is more like .5 BSFC] at the power take off end of a piston engine.


Theoretically, a gallon of gasoline has
enough BTU heat to equal almost 50 HP if 100% efficiently utilized. But
because of heat losses in various forms, it has become history that a
high-efficiency gasoline-burning piston engine (30% is high efficiency)
puts out usable 15 HP per gallon of gasoline burned per hour.

If any piston engine burns only 8 gph, do not expect more than 120 HP
coming from it. And most of the time, it is 5% or so less than that. I
have read articles from another engine builder (their market is
fuel-injected marine Chevy small blocks) that their engines burn holes
in pistons at BSFC of .39. I take it that mixture is too much lean at
that ratio and burns much too hot for aluminum pistons of a working engine.

I have to see third-party dyno verification before I believe that 8 gph
will put out 190 HP.

Thanks,

I agree with the rest of what you say Mike.
