That's retarded. If he took a C4 vette and did that I wouldn't care so much, but why take a C5 with an LS1 and swap it for that? There is no acceptable reason an I'm gonna have to agree with Joo on this one...

Ha ha, tell that to Audi, they really need to know, their R10 (which is a diesel) lost the LeManns by how many laps? Oh wait, it didn't, in fact it came in 1st by a large margin.
Diesels have enormous advantages over gas engines:
1. No risk of pre-detonation, regardless of cylinder pressures, which means you can force in as much air as the block and internals can handle. No need to increase octane or advance the timing.
2. The Diesel cycle is more fuel efficient, because the fuel burns as it enters the chamber, as opposed to being ignited from a single point and spreading outwards as gas engines do. Diesel fuel also has more energy per unit than gasoline.
3. Diesels run much cooler, thus can be pushed much harder before reaching the same temperatures of a gas engine producing less power.
4. Diesels are torque engines, producing far more torque than any gas engine of the same horsepower, and we all know what Shelby said.

Thats because the A/F ratio is waaaay different in a diesel compared to petrol. 12 PSI may be a lot for a mustang, but 40 PSI+ is pretty common among trucks. Meaning you need HARD F/I to get them going. A supercharger wouldn't be able to push them to that limit, meaning turbos are the only way to go. Instead of having a choice between Supercharger, Turbo, and nitrous. You only have turbo. Sure you can start slapping on multiple turbos, but at that point your getting light in the wallet. Look how badly diesel cars suck. Golf TDI for example. Expensive, underpowered...
2. The Diesel cycle is more fuel efficient, because the fuel burns as it enters the chamber, as opposed to being ignited from a single point and spreading outwards as gas engines do. Diesel fuel also has more energy per unit than gasoline.
Diesel is also the most expensive of daily fuels. Yes, it's cheap now. But when gas becomes an issue again you'll see $5+ diesel prices. Given the current trend of "going green" diesel won't be popular among the hard left wing. And I'm fairly sure diesels produce more pollution. Yeah, none of us care. But some diehard hippy in his Prius do...
3. Diesels run much cooler, thus can be pushed much harder before reaching the same temperatures of a gas engine producing less power.
They also run much shorter powerbands. Instead of a 8000 RPM engine that can handle revs to the moon, you get a 4000 RPM engine.

MustangCat, you completely missed the point, your points were kinda valid, but we weren't discussing the price of diesel.
First off, get your head out of Octane land, the biggest difference between a diesel and a gas engine is that there is NO A/F ratio, you are at full air all the time, the air supply is not regulated at all (except for the boost controller), the throttle controls the rate of fuel and nothing else.
Second, 40 psi is not the norm for a diesel engine, the largest and most powerful Diesel engines on the road (tractor trailers) average around 25psi. Most light duty diesel trucks average less than half that. If you were to cram 40 psi into a cummins or powerstroke, you would be touching the 1500-1800 ft/lbs of torque range on pump Diesel.
Diesels have no use for nitrous, they have Propane (which is Nitrous for Diesels), which also happens to be cheaper.
And since you obviously didn't watch the video (come on, you would have at least commented on an 11 second 8000 pound diesel truck), you have clearly made up your mind already, so I won't argue with you any longer.
Because we all know what Einstein said.

i have a friend pushing 65 pounds of boost and is about 1700 foot pounds of torque

you are incorrect here a bit they use nitrous to cool down there intake and turbo temps

but yes diesel is going to be racing of the future or at least of the smart ones

I recommended Electric for the future of racing, and I'm in octane land???
What makes more sense:
8000 lb. diesel truck for racing
3200 lb. petrol sports car for racing
You can set up the truck with a banks turbo, tuner, stiffer suspension, straight pipe exhaust and all the other mods and spend $8000 on a 12 second truck. Or spend $3000 on a sports car with a supercharger and have a 12 second car. LOOOOOOK at all the mods that guy had...TWIN TURBOS! Twin Turbo a Viper and see what happens...
If it WERE a good racing application...it would have been done already. Dodge Challenger, Chevy Corvette and the Ford GT500 would all have turbo diesel engines if it were that great. All the big companies would know it long before we would. They have billions of dollars invested in testing and experiments with engines. It's cheaper, more effective, more reasonable.
Your obviously obsessed with diesel, so I won't argue any further.
