last year my mate had a supra twin turbo (he went on the fast and furious buzz) and he took us out one sat morning about 7.30 am .it was lovely and damp in the air with a bit of mist , he'd just spent £2400 on two new turbos on it and we got 149mph . but just as i was shitting myself he then said look down and showed me we were in fifth gear and the bloody thing had six gears !!!!!!!! we didnt go any faster cause the round about signs were coming up. the thing was rolled at 403 bhp thats the fastest ive ever been in a car but he reckons the damp definitly made a difference.
