KiloWatt Conversions?

Does anyone know of any sites relating to Rear-wheel to fly-wheel kilowatt conversions? Someone told me once that it was 50%, but that sounds like too much to me. Also, it would be different for different cars would it not??

kw = hp x 1.34

Thats fine, but what I want to know is rear wheel kilowatts to flywheel kilowatts. Like, to calculate the drag thru the driveline?

average is 30% loss

its the other way

HP=KW x 1.34

in english it means that 1 killwatt is 1.34 horses.
so a 100kw car is 134hp

but yeah u will lose bout 30% down the drive line

An engineer once told me that a rough way 2 figure out horsepower at da rears is - KW at da fly = HP at da rears. ie; 300KW new GTS has 300HP at the wheels - or approx that. I dont know how much truth there is 2 it, but when someone like an engineer tells u something u kinda accept they know what they're on about.

Ta for the help guys, 30% sounds more accurate than the 50% I was told thats fer sure! Smile

Yeah, I've heard that too actually..

which is basically a 30% loss (a bit less that that), but 30% is a nice conservative number that should more likely be over the figure than under
