I was at a track day today at Sandown. Aside from a Caterham there was also a Gallardo and Murci for hot passenger laps with a professional driver. I was having a ball and the car was really hauling ass, so much so that I was overtaking most cars on the track, apparently including the instructors when they were driving. My car easily pulled away from the Gallardo's on the day, which was confirmed when not one, but two of the instructors approached me and remarked that my car was noticeably faster than the G cars in a straight line when they were driving. So Ellen and Rob and the rest of the F car bashers, a 550 with nothing more than airfilters and upgraded exhaust, comfortably out accelerated the Gallardo from 100-250kmh. BTW, the first instructor to bring this up, just recently had an F1 test, so he's no slouch, meaning it definately wasn't me having greater turn speed. There were also not 1 but 4 Gallardo's there, so it wasn't a dud car either.
