Just going through my files and found the attached pictures.

John Hobbs drag raced in the UK at the same time as me although he was into the bigger classes and was a whole lot more successful with a string of world records in standing start and flying distances. The last bike he campaigned in the 70's and early 80's before retiring from the sport was called The Hobbit and was powered by twin 850cc Weslake Triumph motors with two superchargers and a 50% nitro mix.

Riding a top fuel drag bike wasn't likened to sitting on top of a hand grenade with the pin pulled for nothing as one of the photos shows. The big end cap inside the piston wasn't posed - that's where it jammed! Before he retired, he made it into the very low 8's with terminal speeds of over 170 mph. There were only 2 or 3 people in the world at this time who could give him a run for his money.

Running a circuit racing bike is dear enough, but a drag bike soaks up seriously big money!

Intense!
They are going to blow up a bike tonight at about 5pm at MCR in Dunedin. Apparently last year it took about 45 minutes for the bike to blow. throttle pinned fully open, air-cooled bike in neutral, BOOM!

If i am not mistaken,that bike has been resurrected and being raced at selected events.
There was mention of it in Classic Bike some time back where it was ridden at a sprint by John Hobbs.

Yep, he runs it at 2 classic events a year. Got a photo of it covered in bird shit and cobwebs when it was dragged out from his shed after many years. Nice photos BTW!

Ah, one should think I'd learn not to click on youtube links on of these days. That's another hour down the drain... :(

Not time waste as such though - all sorts of cool things from turbo hayabusa go-karts to hovercrafts :D

Love the comments about motors or generator that are over 100% efficient. :P
Break the laws of physics why don't you.

It would make sense to include thermodynamics 101 in the primary school curriculum - then we should never have to listen to more bogus about perpetual motion engines and related bollocks.
