European Finals 2016

Set up, scrutineered, everything good to go, right? Nearly…

On the first run the large turbo came off its exhaust connector on the launch. The turbo dropped about an inch and touched a wire, which caught fire. 7.39 with a PB 60′ of 1.087 though qualified us 5th after the first round even though most of the run was on minimal boost. The small fire was extinguished in the waiting area at the finish after a brief “FIRE…FIRE” moment.

It was a tad busy on the banking…

Unfortunately on our second run just edging forward to the burnout box there were some unpleasant noises from the motor before it stalled and locked up. Three valve heads in cylinder number 2 had come off, one lodging itself in its port and the other two damaging the piston and head so we were out of the competition.

One theory is that a valve was slightly bent at the previous meeting when we popped the manifold. Valve spring pressure can mean that a slightly bent valve will straighten up and seal properly when it closes, only to return to being bent again when it opens, This repeated flexing ultimately causes the valve to fail some time later.

We’ll need to get the head skulled or welded and fit all new valves but hope to be out again either at the National Finals or the Extreme bike weekend. In the meantime good luck to our fellow competitors in Top Fuel Bike, see you next time!

PS congrats to Rene van den Berg on a storming 6.15 @ 229mph!
