Well it was Ahmed on the dials so perhaps Harvey is only 50% to blame.

This was Marks 1st big Torque engine back in 1999 he expected 500bhp but it did not make it so unsafe ignition was added to break 500bhp.
It was Dynoed same day as Bruces 541bhp .
It came runner up at TOTB ran a 11.8 @ 127mph quarter 0-100 8.1 & set a RWD Topspeed record so I guess Mark knew the direction to take his engines. More to an engine that outright Power & Mark has never looked back with this type of engine.
