That at Dastek Sammy? it's in Dalgetty Bay... been there twice myself now (infact there's a thread for one there I'm orginising in Feb if you fancy going to that too!)
They do two power runs and don't drive the car, other than onto the rollers and back out into the carpark
I know a couple of the guys that work there and they really know their stuff

170 will be the figure in Ps... It's the 'European standard' and is a little higher than BHP.

Had my first RR back in summer and the surprising thing having previously never been to one is the amount of noise the car makes when being revved the nuts off it. It sounds like a jet fighter taking off.

I've done 3 rolling road days. TBH only one of them was done correctly and returned a reasonable figure.
The first day was at Emerald. Mine was the first ZS and I am certain that they still had the tyre size for the MGF in their system, so the power & torque figures were completely wrong.
The second day was at B.D. Engineering in Newington. We took 3 cars along to them - a ZT260, my old green ZS180 and the Twilight ZS180. All 3 cars on that day were around 10% down on power by my reckoning. The ZT260 made 236BHP, the green ZS was 163 and the Twilight one 186.
The third day was at a rolling road in Essex - I can't remember the name, but I told Phate about them. They did not give flywheel figures, just ATW figures. The Twilight ZS180 made 167.4HP ATW, which equates to around 205BHP. This was the only RR day where they measured the actual tyre size of each car using callipers prior to the car being put on the rollers.

The rolling road in Essex that I couldn't remember was ATSpeed Racing in Rayleigh. Contact phone number is 01268 773377.
