Whoopsy:
tso:
I have never understood why it is interesting how much power an engine can produce at the crank, and why people are so involved in making % calculations. Isn't much more interesting and relevant how much power a car can deliver to the wheels
At the same time this would eliminate the hole story about whether a car delivers or not.
Some people wanted to correlate what they measured with what's published by the manufacturer.
I never buy into the whole % loss thing.
Take the example of the 570S and the P1 for example. They uses basically the same engine and the exact same gearbox. Say those guys say a 15% loss, why would a P1 needs 110HP to drive it vs 85HP from the 570S?
