The "finished" article, and its not just for show, this bike will be properly used!! Pretty ain't it! 46 just happens to the racing number issued, and pure coincidence that Valentino shares it with Andy  |

Thanks Tony. The black hose from the carb to the blower was replaced due to a schoolboy error. When started the bike ran fine, blipped the throttle all OK. When the throttle was shut the hose collapsed completely flat! Doh!!! The engine was turning the blower but the butterfly being closed cause a sudden vacuum in which overcame the ability of the hose to stay hose shaped. Now replaced with shiny stuff that will stay hose shaped  |

That is, indeed, very pretty! And when something is pretty AND functional - well it can't get any better, can it?  |

Thanks for the positive comments, much appreciated.
I am waiting for the weather to warm up a bit so I can start it and make sure it does what it is supposed to.
When the time comes I will video it running put a link to it here.

Well it been around a year since the last posts on Dslam’s blown Triumph drag/sprint bike, so its time for some updates.
The original build design & construction had blower-drive from the crank pulley to the Aisin supercharger but toothed belt.
This has been re-engineered to have the more traditional “double V belt configuration” (and of course, this stuff isn’t all available off-the-shelf so machining had to take place to get the ratios and alignment etc all sorted).
Although the position of the SU carb and its remote float bowl, along with induction pipe/manifold to the blower was engineeringly all AOK, the possibility of damage should the bike be knocked or fall over gave cause for concern.
Following much Al welding to form a new induction pipe/manifold, the carb and float bowl now reside in a more protective location.
The only remaining tasks (apart from the shakedown runs and final set-up) are to manufacture a new fork-brace, and carry out modifications to, or fabricate a complete new, exhaust to allow a temporary silencer to fitted so the machine will pass the strict noise regs of the Brighton Speed Trials.
The issue being with a blown motor (and running methanol) is that any back pressure is detrimental.
Photo shows the new double V belt drive, but un-revised carb position
