171.600MPH from a single cylinder Velocette at Lake Gairdner, South Australia..!!!
Wow....an email from Australian Velo Clubmember Stuart Hooper with the news that at the speed week trials on the salt lakes at Lake Gairdner in South Australia his supercharged single cylinder Velocette did 171.600mph.....
Stuart has set previous records at Lake Gairdner and also at Bonneville Salt Flats....
His email follows....
Hi to all,
For the first time in many years Lake Gairdner Speed Trials were unaffected by wet weather. The surface was initially a little rough and the weather very hot requiring a careful eye on engine temperatures and excessively rich mixtures to ensure the engine survived the meeting. After a steady sighting run to check out the new body and steering geometry the Big Velo ran 166 mph on its second outing !!!! This was good cause for celebration as the Velo was now the Worlds fastest British single surpassing the fantastic Vincent Might Mouse of Bryan Chapman.
After a photo session day I decided a higher speed was possible and lined up again with a bit higher gearing and a higher ratio supercharger drive. The third run was only 152mph but this was against a 15 to 20 mph headwind so it was back in line for another 8 hrs for one final run. Friday morning was calm and cool, ideal conditions.......... but the morning ticked inexorably by with one delay after another and a headwind starting to flutter the flags and things looking like the meeting could be cancelled without another run. Finally the track was clear and the Big Velo boomed away from the line with its nearly 100mph first gear into a 7 to 10 mph gusting head and slight crosswind. By the time I changed up from third into top at 156mph the bike was weaving and darting about somewhat in the ruts on the track and the odd gusts of wind, but with the throttle hard against the stop one hand hovering over the clutch lever and the revs climbing towards the 6500 mark the track markers started to slip by faster and faster until the final timing light flashed past and it was time to slow down with the old Venom single leading shoe brake smelling as only red hot 50 year old asbestos can. Back to the pits to see the crew flashing lights, cheering and jumping around !!!!......... 171.600 mph !! ..... A fantastic end to a great week....... The Velocette name is again in the record books where it belongs !
Worlds Fastest Velocette.
Worlds Fastest British Single
Worlds Fastest Single Cylinder Sit On Motorcycle.
A sincere thanks for the support to my crew and all of you over the years,
Stuart Hooper
ps..... Just how fast can a Velo go ?
In the preparation for this attempt, Stuart supercharged the single cylinder engine and sent these photographs...
