No, I've actually seen 750bhp in the last few of days!

But of course, it's all speculation. I'm not sure anyone outside of Audi really knows.........

Are the 720/750 bhp comments really about the new Diesels?

I was thinking that he may have been refering to the slightly larger restrictor that a Petrol/Diesel powered LMP1 Coupe would now get to compensate for Air-con?

It was on another forum that I read it but for the life of me I can't remember which thread (it wasn't an obvious one plus I can't be bothered to look for it!), but yes, definitely 750bhp was the figure suggested for the Audi diesel engine. The point being made was highlighting just how far behind the Pescarolo's could be on outright bhp this year let alone torque, even with the updated and lighter Judd engine.

But I would reiterate that unless Audi release a statement confirming this figure (which of course they won't in the forseeable future) there is absolutely no reason to treat it as anything more than speculative.......

The R10 is powered by a V12 turbo diesel that produces 650 hp and 1,100 Newton-meters of torque.

That's Audi's story, anyway.

[Bentley03]

Personally, I feel far more comfortable accepting Audi's official figure. But the groundbreaking nature of this engine still leaves me wondering if............

It was about LMP1 Coupe + A/C.

fantastic, what is it with putting noise restricters on racing cars nowadays, the noise of these LM cars is probably the best noise's i have heard in my 16 year life and i dont know why they want to make them quiter??, the but i guess it is a lot more friendly with the air con in the cars now but im thoroughly against the noise restrictors and ill be damned if i cant make it to donington in august before they imply noise restrictors for the 07 season

[Flat12-Aircool]

Well there's a bit of a debate over if they will be quieter.

113Db is to be measured 15 meters from the trackside, which is pretty generous compared to other tests like the British GT which holds the detector closer to the exhaust.

TVR's may still have a problem though, last year at Silverstone they we're clearly the loudest. Vrroooommmm! Ouch my ears!

That is quite loud. Is that 15m in front of the spectators, or 15m from the track.

The tests by the exhaust are not normally done at full revs. Which helps.

They will be taking readings at various points on the circuit fifteen metres from the track.

[Adam43]

That is a much better way of doing it. If the aim is to assess the noise pollution to the surrounding area and the effect on the spectators.

[Flat12-Aircool]

I suppose the unique problem endurance racing has is that quite often the races go into the night and in the case of 24hr's its also into early morning.

This creates an extra aspect for local residents to moan about, so I can see why the ACO want to do it. It's just a question of is 113db the correct level or should it be higher?

Plus, sorry to start with the conspiracy theory's again, but these new Diesel LMP's are going very quiet compared to most other cars.

[Flat12-Aircool]

It looks like we have a partial answer to the mystery of how the ACO will police the Air-Con in GT1 and LMP Coupe's etc.

Here's a translation of the latest Press conference at Paul Ricard :-

" To control the temperature in the cockpits, a sensor will be installed close to the helmet of the pilot."

But it begs the question, what if the sensor malfunctions halfway through the race and stops sending back data? What penalty will there be if a temperature infringment is commited?

Still too many "if's & but's" IMO.

Apparently the airco will not be enforced in 2007 either, at least not for closed LMP cars.

Is the installation of an air conditioning system inside the car a problem?

« No, it's not, but in fact we don't have to use an A/C unit. If the air temperature inside the cockpit is not too high, we don't have to have one. The problem is for front engined GT cars. In the 908, it won’t be hot. »

[old man]

Does Air Con rule apply to GT cars?

[SALEEN S7R]

Hmm, I dont know but I dont think it was mandatory for the 2006 race. As we all know however Corvette have been running a air conditioning system for years.

It was recommended in 2006, although the rules in the beginning of the year stated it is compulsory. In 2007 it is supposed to become mandatory.

[AU N EGL]

From the ACO LMGT1 regs:

ART 14.6 – Temperature inside the cockpit :

The ambient temperature around the driver :
- must not be higher than 30°C (86°F) whatever the
temperature on the outside when the car is in motion ;
- must go back down to 30°C in 5 minutes maximum
after a stop of the car.
An efficient air conditioning system comprising a compressor, a
condenser, a pressure reducer and an evaporator is compulsory
for the closed cars. It must be described on the homologation
form and approved by the ACO.
Application : recommended in 2006 and mandatory as from
01/01/07.
In 2006, if the car is not equipped with an air conditioning
system, the cockpit must be effectively ventilated. The
ambient temperature around the driver will be monitoring
during the events and the results will be given to the
competitors for information.

[old man]

Thanks for that, a lot of cars will require changes then

This thread was an insteresting read.

An A/C system or do you mean cooler suits ? I wasnt aware they had been using A/C ..... since when ?

[gwyllion]

I also thought they just had cool suits and helmet ventilation.
