Re: Track day Silverstone GP, 21st August

Bjorn, Nadine and I had a good day yesterday. Didn't see too much of Fangs on track as we were in different groups so I will leave it for them to post their own story, but I heard the viper ran well.

My car ran well too. Glenn and I were sharing the driving and we always had people queing for a ride so we made a good number of people happy! We managed all 8 sessions giving us just under 4 hours of track time during the day. I have never had such a large fuel bill before (over 110 litres) so clearly the car is living on full throttle that little bit more now we have made the improvememts to the handling. Cerainly my confidence in driving the car harder is up and I think Glenn is going quicker now as well.

Very pleased that the new (newly modified at least) anti roll bars gives such a good adjustability so that just one hole difference gives a positive response to handling. Maybe I should post some pictures to show how I converted the standard GTD bar into an adjustable bar for very little money?

Only issues we had were one of my exhaust clamps vibrated its nuts loose and the front wheel bearings need a service now as they haven't been looked at since being bench fitted. Need to eliminate a small amount of play. I think the exhausts will need repacking prior to Brighton Speed Trials for Wendy but that too is straight forward.

It was slightly damp in the morning which made for interesting driving as there was a lot of oil down from previous dry race days not yet washed off the track but I was very pleased with two four wheel drifts managed through the long corner of Vale, playing the throttle in third gear. Not perfectly balanced drifts but drifts nonetheless. I didn't expect to be able to do those at all on these tyres (road going Avons) so am quite pleased.

Can someone please explain the physics of why, when you turn into a corner and get initial push, if you accelerate with an LSD, the effect of accelerating and LSD combined turns the nose of the car in very effectively?

Paul (with nephew) was up there taking pictures so hopefully he can be persuaded to post some. Chares had to pull out of driving but came to spectate anyway, as did Martin Potts who brought up his hairy looking MGC V8. Always nice to have spectators supporting.

I was also driving the race porsche 993 RSR so jump to that thread if you are interested to see how that went.
