Jonathan & Hugh,
Did a few tests last night with Woosh (130i) and an Audi A4 down at your testing place.
It was bloody wet, took some time to get some heat in the tyres
Ended up with a best run of 7.85 in the 125 with one on board.
Woosh would have been at about 7.70 with one on board.
Mind you, this was in the wet with no tyre heat and a fair amount of slippage on launch.
Will upload the graphs today.
