I'd say 90-100 at the wheels for a GLT in good shape. Husky will have to tell you what I was getting at the wheels (only seen from behind the car), but IIRC he said the wheel figure was what he expected the crank figure to be, which was ~115bhp.
Transmition losses on a chassis dyno are mostly down to the rolling resistance in the tyres, especialy on dynos with two rollers, as you have two contact patches and you are distorting the tyres in two places at once, inflating the tyres to very high pressures dramaticaly reduces transmission losses. james's car makes 110 ish at the wheels, 140 at the flywheel, my car makes 158 bhp at the wheels, which was 202 bhp at the flywheel, which helps show that the losses through the transmition also increase if you make more power, (more heat/ friction in the box, more distortion of the tyres etc) hence a low powered car such as my beetle when it had the stock 1200 engine showed 30 bhp at the wheels and about 38 at the crank!
HI CAM
I have just put my 360 on the dyno. I managed 104 hp or 78 kw. this was from about 3.5k rpm to 5.5 and then it started dropping off. It will be interesting to see how yours compares with the upgrade.
see ya later.

gday Pete!!!
I'll have to have a chat with ya tomorrow when i come pick up the other one - I hope you have got the trans done in it!!!
those are really good numbers mate - teh best we got outta the 2.3s at the last one was ( i think) 75kw - and that was with a 1ggz toyota supercharger hanging off the side!!!
