Zs205
I went on a rolling road yesterday at Atspeed in Rayleigh, Essex. Three runs were performed on my car and it reached 167.4BHP at the wheel. This, I am told, is about 205BHP at the flywheel
Here's a vid of the car on the rollers.

it all depends on the weather and whether the guy setting it up does it 100% right
They're good for a rough idea though

In order to get an accurate figure the tyres have to be measured. Most rolling roads do it by taking the numbers printed on the side of the tyre. These guys actually measured the diameter of the tyres on each car run. If you take the size from the tyres and the tyres have low tread the rolling road will indicate that you have more power than you actually do.
These guys were certainly better than Emerald, who made a complete and utter **** up of the run that I did there in my green ZS. According to them, my unmodified ZS180 made 184.8 BHP at 7430rpm, and the power was still climbing! The torque peaked at 147.2 @ 4937rpm.

Yes, I'm happy with the figure. If it had been much lower I would have been disappointed.
BTW the operator of a rolling road can produce any results they want. Whilst I was at this day the owner of the RR played a practical joke on one of the MGF owners by making his car only show 95.8HP at the wheel. The actual figure for the car was around 115HP.
Mods to the Twilight ZS180 include Janspeed manifolds, de-cat, XPower back box and ITG in the inner wing. Plus whatever Janspeed/MG Rover did to the engine.

Interesting that, so there's a small amount of the unknown with regards the engine internals.
