Just wanted to come back to this since you were there yourself. Despite Laguna (apparently!) not being an 'R10' track, it was in fact an Audi that did the fastest LMP1 lap in the race yesterday, despite a 65kg weight disadvantage to it's far more nimble adversaries. On the other hand, the fastest lap of the race was in fact turned by a Spyder. What we don't know, of course, is how much boost the Audi's were running. |

Just cant run down to the local truck stop and get more diesel for these cars. IMHO diesel fuels need to be standardized for any diesel race cars to get. or refinery to make. Sunoco makes most of the race fuels ( petrol) in N American race cars. Shell makes for europe and elswere. Very close in formulation between Sunoco and Shell. Not much tuning difference when cars cross the atlantic. Diesel fuel should be the same. Forget the Bio-fuels until they also can be standardized. |

I'd guess that race cars run with pretty high compression, so unless they have knock sensors and some serious active retardation/boost control, I wouldn't fill them up with ordinary gas/diesel.

I'll give you Laguna as an example. Creation and Zytek would have won comfortably without countless offs and stop and go's. |

Half a dozen spins for Creation on Primats stint and 2-3 minutes of penalties for Zytek?
I struggle to see how they expect to win with such rookie mistakes. How competitive would a driving team of Johanson/Minassian, and pit crew/strategy from Dyson be? Is it any conincidence that Audi and Penske always seem tp be the last ones standing, competitively, in the last hour of each race. Misfortunes, often self inflicted, seem to take Creation, Zytek and Dyson out of the running before the 2 hour mark. Pescarolo seems to be the first privateer to master speed, reliability, pit stops and strategy. Last edited by JAG; 23 Oct 2006 at 01:41. |

Having had a quick look at Henri's open letter to the ACO (on endurance-info) I'm struck by how measured it is. I had feared that it could blow up into a disproportionate row between Pescarolo and the ACO but I think he succeeds in getting his point across (that he doesn't think the regs have been changed far enough) but that he's still committed to Le Mans.
Of course it could well be that my somewhat haphazard command of French has led to miss all sorts of nuance in there but at first glance it looks like a sensible contribution to the debate. |

I can't concede anything yet. All of you could very well be correct and the diesels may have an unfair advantage. But, I am still of the mind that there is not enough significant evidence due to lack of a fair comparison. I would love to see a developed turbo petrol engine in the back of a well sorted chassis. I don't think Dyson are there yet, mainly because of the Lola. |

I have just read Henri's letter over on DSC and I can see exactly where he is coming from.

His letter really exposes the ACO's not-so-straight choices. He's got the data and explains it really clearly; I'd love to see Dr. Ullrich refute that...
The problem is very well outlined, and even if it's not all down to engine performance, the R10 is running with more downforce without being penalised because of it... and they must get special Michelin rubber to put all that power down better than anybody else on the gird. This is unfair; restrictors should at least insure the power outputs are equal or at least close (at maximum Audi boost, not sandbagging boost...) and then maybe let them run away with their enormous torque advantage because they made a bold technical choice. |

Any turbo car enjoys the benefit of running at various boost levels. So I don't see why this is part of the equation.

No, apparently you don't.
But if the Audi still produces great gobs of torque at lower boost, then it can be run for economy and still run quickly. Why would a petrol turbo be turned down - so it can drop further behind? |

Maybe we can force Audi to use a pro/am driver line-up, change tyres at every stop, or take a 2 minute penalty? It's widely accepted, all things being equaly, P1's are at least one second quicker than P2's on a regular track. The RS Spyders fastest lap was three tenths quicker than the R10, would a P1 Spyder be 1 to 1.3 seconds quicker? Obviously some people made up their minds long ago.
