Here is a history of my bike. . .so far. . .

1984

My dad's shop demonstrator. Stock, except lower fairing and mirrors removed: 11.1 @ 124mph

1988

Removed air filter. Added CMA 6" rear wheel and banana pipe. Lengthened swingarm 4". Boost increased to 15psi with adjustable wastegate and rising rate fuel pressure regulator. This causes the ECU to switch off the injectors during the run, but still makes 10.71 @ 131mph. I bought the bike the following year, and kept it dry stored until 1996 when I bought the remains of Mick Hand's aborted twin turbo 750 project: an engine in pieces but with lots of homemade goodies, a Rajay turbo and an inlet manifold.

1998

Modified as below except for swingarm and lowering. Lots of frustrating electrical and other teething problems, but it managed one decent run out of the blue....9.44 @ 139.5mph.

1999

OTHER BITS

Ford Escort coil. ZX6R brake and gear levers. Harris footpegs. Scitsu tacho. MrTurbo boost guage. Dyna shift light.

ON THE SHELF (for next year maybe!)

Semi-automatic 3 speed gearbox. 904cc billet block and Wiseco pistons. NOS nitrous oxide. Dyna stutter box. "F" turbo compressor. Billet clutch basket. Rods with 18mm pins.

 

Due to an oiling problem, no runs this year, just lots of engine and turbo damage! Oh well, there's always next year....

 

2000

Over the winter I fitted the "F" compressor, .25 exhaust housing, stutter box, a new Mickey Thompson 7" slick, and pinned the big-end shells which had spun around in the rods last year. On it's first run at Santa Pod on 14th May, it went 8.699 @ 162.15mph, on 23psi boost. Two runs later it blew the turbo up (again).
