Hi there!
What is the typical difference between WHP and crank HP on motorcycles?
I know that on AWD cars, WHP is about 20-30% lower than crank HP.
Thanks; D.
10 to 15 % if you use the very optomistic Dynojet dyno results for rear wheel HP. 15+% if use a brake dyno for RWHP. Depends how overly optomistic the crank number is also. Some manufacturer's quote a number from a blueprinted engine, no oil pump or water pump drag, etc.
my dyno is simple....you crank and let the engine rip:
1-Big smile=enough power
2-Big Grin= enough to get u introuble
3-Smile=maybe u should add a few modifications....
