I started off with BHP which reckons it takes off 10% for transmission, but doesnt include aerodynamic loss....it showed 232 initially then fell as the car got hot, down as low as 151bhp (although that may have been poor drvier technique!!) most reading were in the 177-200bhp area. On the 0-60 front I had a bit of trouble getting it to behave and by then the car was very hot, but I turned in a best of 5.5 secs and a worst of 6.2.
Technique had a lot to do with it as did the engine heat.....its been a real eye opener to see the difference made by heat.

As you know, GTAs dont like running rich, even slightly...it massively reduces top end power, even an innacurate coolant sensor can make the car feel so sluggish. The problem with the GTA is it gets hot and retains heat so easily, that the ecu richens up the mixture to prevent det, and retards the timing. The other problem is that the V6 pipe can retain heat from the charge very easily, and even though the air is intercooled, it is then warmed up again by this very pipe.On some of the Europa Cup cars, they had a black Turbo pipe and a silver V6 pipe..

My brother has a 20valve turbo. Lovely cars; his has a hybrid turbo, stainless exhaust and is chipped. I think the previous owner had it on a rolling road and it produces around 240-250bhp depending on boost setting. It's very quick anyway! Obviously struggles for traction on slow corners and from a standing start, but on the move it pulls away from my standard GTA in third and fourth.
I posted a thread on their forum a while back and they're very complimentary about the GTA!
