well, A big problem really, As you can see and hear in the attached video at 3:15 seconds in - the car loses most of its power. A quick check found that the spark plug electrode in #3 had melted (presumably due to detonation). In the video you can see that boost is well controlled at approx 1.05 bar during the previous two laps but suddenly it spikes to 1.3 bar and stays there. From the sound of the engine this is as a consequence of the problem - not the cause of it. I have checked the timing and the cam belt tooth positioning - they are still fine - but I have not had time to do a compression test yet. Will do one tomorrow.....
