My old 500bhp Saff with Mr. Shead at the wheel ran 12.1 @127mph at the totb qualifier in 2003. Its PB was a 11.8 with a similar terminal.

My 650 conversion managed an 11.5 @ 138mph but on 200mph gearing & tyres at 40psi during a 0-200 mph run.

Will be circa 150 terminal now but not much quicker ET as the old girl aint set up for it.
