Incredible run. That is really outstanding Lawrie with an engine designed for 85hp.
When I did work with nhra I worked with some footage of a 3sec run. They'd take off and shut it down just as fast. As told the centrifugal clutches they use on the topfuel 10k hp engines, if they had a button that you could push at 200mph to engage the "drivetrain" to the engine they'd smoke the tires.
