Diesel Racing

[xterra48]

I know that there has been much talk of the Audi R9 (whatever) being a diesel, but what ever happened to that Taurus Motorsport diesel at that ran at le mans? During the speed LM broadcast there was talk of the car running a couple of ALMS races, but since I have not heard anything about the car, and I didn't see it at the Nurburgring either. Does anyone have some info on this car, I would love to see it finish a race, and am a big fan of diesel tech.

It will be out at Silverstone and Spa. The car underwent some development (same for NASAMAX as well) and so missed Nurburgring.

Apparently there are bigger changes on the way for 2005.

diesel options abound-
most are inline 6
but the VAG v10 from the toureg-and caterpillar developed really showed too much power for the cars own good...
GM has a v8 which runs in their pickups which is alriht
a power boat version with a supercharger, which is quite compact...
but what do these engines weigh? I reckon alot.
the GM unit is near 950 lbs.
actually 948lbs not race worthy- what did the V10 cat weigh?
the truck engines (volvo penta, Cummins, Mercedes, MAN are pushing 1000-1400lbs
or 2000Kg. i think.
and these are 9 to 13 litre straight six motors...
so how can you fit a diesel in any Prototype chassis, with out it being A "V" type and then who can develop these besides CAT and VAG? GM doesn't seem likely to jump in ala V8-
this new set of challengers really changes the look of the field potentially. other than a 4 cylinder has nay inline engine been used before? 8 or 6?
diesel rules.

All European manufactuers have compact diesals in their lineup, with V6's etc.

Audi has just released a V8 turbo diesal in its new S8. I would expect V8 diesals from all of the luxury brands soon.

good news
of coourse the mercedes V6 truck racing engine is good for 1500hp
and 5000nm of torque
do you think it would be legal? at 13 litres?

The Truck engines are weighing in from 1000kg for the range of 9litre up to 16 litre. The Penta 9 litre unit is running 400/500Bhp and over 2000 Nm of Torque, with only a 2500rpm max. This is only really suited to truck racing engines, but they are kicking out 1000bhp+.

For circuit racing the engines are not quite there yet, they need some big manufacturer behind them (Audi for example). But what about the BMW 3litre sraight 6, it has some nice technology behind it.

Also the Jaguar (PAG??) 2.7 litre V6 twiin turbo could be interesting. Is there also going to be a new 3.5 litre BMW V8 twin turbo diesel soon???? Now that would be interesting.

GTTouring, Wrong way around with the weights, 1lb = .45kg.

The Judd/Ricardo project looked promising but it seems to have been abandoned due to a lack of funds.

[xterra48]

IN the good old US of A we dont have nearly a sixth of the diesels you guys have in Europe. The only things a consumer can buy with diesels are VW cars, and big pickups from the big three, and some new jeep liberty/cherokee, and a new E class. But in some states, mine included, you can only get the heavy pickups (NEW!) because of emission rules. Used vee dubs are good by me. The future of racing in enduro events at least diesel. Those without it will loose so much time in the pis as to be un-competitive.

Is this Recardo concern, a decendant of the Ricardo, whose combustion chamber discovery, kept the flat-head engines around for so long?

Are all trucks using exhaust driven blowers now or do some still use a Roots or other type of mechanical system?

It may also be at Laguna and/or Petit. I'm supposed to be doing a story on them if they go.

You can read a story about them here:

I think all the diesels in america run on old-school exhaust turbos

[JAG]

Just reading in a UK Magazine that the top of the range sports models from FIAT, SEAT (VW Group) and a number of other manufactuers are going to be turbo diesals.

I also read that Mercedes are going to drop superchargers from their range in favour of turbos. The artical says that 40% of European petrol cars will be turbocharged by 2008. In the early 90's it appeared that turbos were going out of fashion, now they are back big time!

"GTTouring, Wrong way around with the weights, 1lb = .45kg"

oh right
duh
of course a lmp900 is about 1800lbs and 900 kgs. sometimes my head is on backwards in the morning or is it night?
on with the Diesels!
what do the race truck builders do to up the horsepower and torque? is it simply turning up booost and fuel mixture...and revs an extra 500rpm? they run what 5.5 bar in the mercedes supertruck?
1000hp-1300 and 500nm of torque is a huge leap from production
with one turbo(formula truck Brasil) or two turbos (FIA)
what do they do?? and why is diesel seeming to be the black art of Internal combustion engines?
