Its very real
I see the torquetards are out in full force today.
It's true that you can't make horsepower without torque, but you also can't turn torque into MPH without RPM.
Yeah, you can gear a small diesel to do 0-60 in 4 seconds, but it'll already be well on its way to a top speed of 62.
This maybe splitting hairs a bit, but is the OP talking sports car or drag car? I only ask this as most diesels (Cummins included) are heavier than their gas counterparts. This would really have a bad affect on handling. Look at the Indy car that was mounted midway and on its side.
On the strip, diesels can do pretty well.
So far every example shown (except for the Smyth car which sorta doesn't exist) is NOT a "sports car". Muscle cars are NOT sports cars; they're muscle cars. I'd argue that an Audi R10 isn't a "sports car" either -not in the practical sense of the term, anyway.
P.S. The BRZ chassis might qualify... but, is a real deal/potent diesel officially part of the program yet?

As noted earlier, building a kit car around an existing engine is not equal to swapping a diesel engine into a sportscar.
It is like somebody asking for pictures of red rally cars for their birthday and you post this:
If you want a wow factor, go ahead and put in a Cummins/Duramax. I will say this, they are heavy SOBs. 1100 for the Cummins with fluids and accessories and 900 for the DMax.

But, OH MY GOD ITS A MULTI-MILLION DOLLAR RACE CAR how can it possibly be relevant???!!?
It's relevant because the motor spins to a whopping 5000 RPM, that's why, and it's torque-tarded enough to pull some serious gear and go fast and compete with high-revving SI engines.
A 4-banger TDi engine with boost and gearing in a lightweight chassis could do just the same, on a smaller scale.
It should be a no-brainer that it makes loads of torque and can still be geared to accelerate very fast and also top out well north of 200.I would also note this engine would be far too large to be used today in ALMS.
The simple fact that only a 5 speed trans is used speaks volumes to the amount of torque available. As stated though, it isn't even relevant to he discussion at hand. Why you ask?

How is 5.5 liters with twin turbos "small"? It is ridiculous to even compare. When unrestricted these engines make well over 1000hp and unknown torque. All of this in a car when race ready with a driver and fluids weighs less than an empty Miata.Originally Posted by CBi
Totally relevant, I am glad you are done with this thread.
