272HP ain't bad at all
was that at the rear wheel or expected at the engine?
If you do an excel and get good results, would you mind sending it to me.
If you want what I have been messing with today,
My initial review of the Ron Graves's PI article is not being able to grasp the concept of calculating torque. when I made an excel work sheet, my resulting HP numbers were 10X expected. not knowing how he derived his equation, but I expect the 3.2 contant should have been 32.2 (the conversion of pounds weight into mass slugs)
my approach to calculating HP based upon acceleration times is the calculate the instanaous Kenetic energy at each 1K rpm, then the power from delta KE and time.
surprisingly the KE method gave me vary close results to Ron's equation (devided by 10).
