Basically I've been getting confused
Been looking at the results from my rolling road day at the weekend and the ones posted in the RR graphs sticky thread. The thing striking me as odd is the flywheel HP compared to the wheel HP.
According to my graph its lost 15 HP from flywheel to wheels.
The majority of the others posted seam to have lost 50+ HP
Thinking further physically energy cannot be destroyed just changed into a different form. So bearing that in mind the kinetic energy from the flywheel will loose some energy from heat and noise through the gearbox, prop, diff, half shafts, wheel bearings, tyres ect.
Surely the looses from those shouldn't add up to 50-60 HP ect Big percentage of power to loose. I work in agriculture, and tractors are often quoted with there engine power and PTO power (power take off, shaft for powering machinery) if there's much over a 5% loss at the PTO they aren't very efficient.
So what I'm trying to say is my graph accurate, and why do some cars have such a loss of power at the wheels?
