Brian,
I feel absolutely lousy with the cold. [] I would love to have been there, but went to bed instead.
I won't be at the run on Sunday no, because as usual, Stan is working, and Jack gets bored. I'm hoping that soon (and so is Stan) Stan won't be working seven days a week, and we can join in, on some of the events.

Nae luck dougie but my car benefited from a new screen after KHill last year.
The track was busy busy busy, how many cars were there Ian?
Perplexing to see a red GT3 and white and cerise RS in the "B" group, perhaps RB felt he needed a we shot in the "Bs" after losing it at Duffis earlier on in the "A" group, I hope they paid extra for the privelige!!
I had great fun and apart from a small gravel excursion returned unharmed and full of the joys of 3.2 ownership, perhaps in contrast to another dentist who couldn't resist the urge to explore a smokey 2.0Bar boost in his 944.

Phil, usually you know what you are talking about so please don't be insulted but that's pish about the tyres ( correct spelling []) there was plenty of grip and heating the tyres was not a problem, perhaps your pressures were a bit off, I noticed a big change in behaviour running 30PSI -- oversteer and 33PSI -- nice grip at the rear.

The Michelin Cup that I was driving require *a lot* more heat to have good grip than normal tyres (see below, quoted from
Michelin). So, 71 to 104 deg C in my tyres on Wednesday? No way! It was not an issue of tyre pressure, but one of heat
conjugated with brakes than were too powerful for the available grip...
%FEATURE: RACING-INSPIRED TREAD COMPOUNDING
%BENEFIT: Superior Adherence and Handling
%MECHANISM:
%The Pilot Sport CUP's tread compounds are formulated to have a maximum energy absorption (hysteresis) at competition
%operating temperatures (in the neighborhood of 160-220 F / 71-104 C). This is an appreciably higher temperature range than the efficient
%range for standard UHP street tires and provides improved traction and cornering grip for road racing situations.
Sorry Phil but I just don't buy it.
I was using DunlopFormula Rs and while they are clearly a different compound to the Cups they are also closer to the cups than road tyres and they provided the usual good grip.
Scott with the 993 2S has a pyrometer so we will have to check things out next time.
I don't see how you could guage that your tyres didn't achieve the min operating temp ( 71C) also there is a definite connection between pressure and tyre temp.
I love this stuff it keeps me awake at night!
Please don't be upset by this kind of banter as you will soon find I am seldom wrong!!
Occasionaly I am wrong but this is usually due to bad advice from Boydy, Mike N or Frazer , I would include the Griff but he hasn't a clue
