UK-POLOS.NET - THE VW Polo Forum

Just incase anyone is interested, here are the results I got for my GT at the Club Polo Rolling Road day at Wilcox race engines on Saturday.



I got 73.6 BHP at the wheels, which I was very pleased with.

I'm not sure exactly how much power at the flywheel it has, but I believe you use the following formula:

Power at flywheel = Power at wheels/0.877

If that formula is correct, mine pushes out 83.9 BHP at the flywheel

It would have been nice to have more GT's at the event to compare figures, but there was only one other GT which made the same power as mine anyway.

cool i blive its around 12% for a front wheel drive transverse mounted engine but as witgh any thing it changes i.e. a lower viscosity oil in the box will lower the persentage

Yeah, it would of been nice if they gave us the flywheel figures but they didn't.

There can't be a 'set' general percentage loss between flywheel and road wheels, as all cars are different. There are differences in gearboxes, driveshafts, hubs and wheels which all give different variables.

So I guess I would have to have it Rolling Roaded again to find the flywheel figure.
