Guys, let me first say that I have only ever had 1 engine on the dyno that I built, so I am not real knowledgeable on dyno horsepower of how its calculated. But a recent discussion has made me do some thinking, because what I am being told doesn't seem to add up to what I THOUGHT I knew! What would be the typical drivetrain loss percentage wise, on a typical 727/8 3/4 or a 904/ 83/4 combo, or perhaps even a 4 speed/8 3/4? I do recall the old mopar chassis manual had some information it it regarding the amount of horsepower it would require to run a certain MPH at a certain weight, in the 1/4 mile. And there are various online calculators that seem to mirror the results.......Just trying to learn here guys, so I welcome any input! This is NOT directed at any member/car/engine/track/dyno personally, its to clairify my own knowledge!
