hey mayf - im NOT going to throw my dog in, just curious
1. whats does the inertia values of the gears have to do with steady state
hp loss ?- how bout the inertia of the driveshaft, axles, tranny mainshaft
, ( clutch - pressure plate - flywheel - torque converter ? ) etc. ?
2. if they do factor in, the inertia values seem rather small for
automotive style gears
3. where do your calculations account for viscous frictional drag of the
transmission fluid (manual or auto) and rear end fluid, which are major
players in hp loss thru the drivetrain. gears chopping thru gear lube at
high speeds drain alot of hp
4. do your calcs consider tranny bearings, u-joints ( this could be
somewhat significant based on pinion vs. tranny angle and offset) axle
bearings, brake drag?
5. auto trannys burn some hp to drive the main pump
6. thats quite a disparity between asphalt and concrete, more than twice
the amount?????(Power increase % on asphalt is = (89/ 831) * 100 = 10.7 %
Power increase % on concrete is =(40 / 831) * 100 = 4.8 %)
just curious- positive regards without flaming -doug @ black radon
