Unique FTO dyno results

Just wondering if the dyno results are kw at the wheels? or at the flywheel?

How do you change at-the-wheel figures to at-the-flywheel?

From the figures I would guess it was at the wheels figure. Divide by .7 to give a rough idea of flywheel figure.

only problem is the car's a tiptronic one so its a bit closer to divide by 0.6

Ahh, now I get it. I was also a little confused, I checked out a few dyno results of fto's on other websites and some of them claimed to be putting out around 160-180kw. So this must be at the flywheel right?

A stock standard GPX puts out 147kW at the fly-wheel right?

Well i always thought that to get kw from bhp..you would divide by 1.345

Since the fto is at 200bhp, doesn't this equate to 148.7kw???

1hp= .75kw
hence 200hp = 150kw

you guys are all pretty close in your calculations. but your differences come from the approximations you used....

for the record:
1hp=0.745669872kW

or alternatively
1kW=1.341022090hp

but close enough is good enough eh

160-180 in most cases will be at the flywheel, the only ones getting that at the wheel's will be turbo / supercharged. with a heap of internal engine work done
