Iv had 3 cossies 2 saffs and 1 3door, the most iv had out of any of the is 125mph in 4th and the 3door was 350 bhp same mt75 gearbox as a g plate 2wd, so unless hes got 20"wheels,i find it hard to believe, ask him to take you out in it and proof it!

Just for info the 2wd Sapphire uses a Borg Warner T5 box not an MT75 box - the 4wd uses that.
Top speed of 2wd in 4th at 6700rpm is about 123/124mph - clock could be 8 or 9 mph reading above that.

LOL just read th ethread and checked what my RA does in 4th from a RR day - 106mph@7,600rpm manic gearing aids aceleration though. 125 sounds about similar to a UK scoob.

just got this e-mail off the man him self.
