Not 928 related, but interesting nonetheless...

Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm

Oh, here is one for Viribus:

The BMW 530d and European Honda Accord (which is actually an Accura) diesle engines have their rev limits at 5000 rpm - you had asked me for examples of high revving diesel engines some time ago.

Seems a long time ago now - I remember it was very cold. BMW Diesel powered shark.

So----what suspension mods do you think I'd need for that engine?

Why?

Becaue of the torque. For street driving and cruising, you can benefit a lot from the incredible torque of the new turbo diesels. You or your automatic don't have to shift much, because there is always enough torque available to accelerate the car. It's a very soothing, relaxing type of driving, even though it can be very fast. There are turbo diesel cars in production in Germany that have a governer to limit them to only 250km/h (155mph) speed. They zip from 0-60 in 7 seconds or less. And when it comes to accelerating from speed, e.g. for passing aonther car, these things go off like crazy. Granted, you don't have as much of an rpm band, but you really don't need it. It's a revelation to drive one of those.

And they do it for about 40% less diesel than a gas poered engine would comsume gas. This means, you have a much larger range before you have to get fuel again Some can go as far as 600 miles on one tank...

Think: Audi A8, BMW 7, Mercedes S, VW Phaeton V10 (313hp)

PS: No, they don't sound like a Cummins, and they don't blow black smoke, due to catalytic converters, smoke filters and low sulfur diesel fuel (available in the US starting 2005, I believe)

In a moment of lucididty I considered a mass conversion to either natural gas or diesel in my 1981. I wonder at what would be required. I was driven towards tis insanity by talk of the AMG C300D sports coupe and the Opel Common Rail deisel. Also, though the company escapes me, there was a German firm who had developed a high output 1.7L turbo diesel for light aircraft and were working on a 4.0L (perfect for the 928).

Anyone share my insanity?

Try crankin that baby back around to 0 degrees TDC, to adjust the TB!

Nicole,

I guess I can see the usefulness of diesel for everyday driving... Plus there's the bonus of being able to escape pursuing aliens(they can't kill your ignition) but I think I'll stay with gas for now. One day I'll replace my truck with a Dodge Cummins TD but I'm happy with my shark powerplant as it is. Well, I wouldn't mind dropping a euro CIS motor in it, but that's another story.

Saw a really cool littl diesel racing (yup, racing) engine at PRI last year.

IIRC, output was around 400 HP with gobs-o-torque. Looked to be a nice size for a 928 engine bay.

Wish I could find where I put the data on it. Believe it's for an upcoming (extant?) racing series in the EU.

Although the thought of a diesel 928 makes me sad, it's a genuine shame that the US doesn't get the amazing new generation of oil burners like Europe, everywhere else. They are light years beyond cars like the Olds Cutlass diesels that sucked so bad that owners were glad for the permanent soot layer on the back of the car because it covered the badges so people couldn't be sure what they were driving. I'd look very close at one for commuting, family duty. 5000 rpm out of a diesel with the inherent torque and no rattle makes the 'penalty' of them disappear. But then again, I'm single with no kids, what the hell am I thinking?!?
That picture of the crankshaft is mind boggling .

The mind boggleing thing is that if you have a modern turbo diesel with, say 200hp and a gasoline engine with 200hp, there is no way for the gasoline powered car to pull away - no matter how hectic the driver shifts, the diesel will keep pace. When the gasoline driver has to stop for refualing, the diesel driver can keep going for almost twice the total distance. Also, the price of modern gas versus turbo diesels is not much different anymore. The only handicap for the diesel is its (usually, but not always) higher weight in the front. Nevertheless, they can be really, really sporty and fun to drive fast. One of my friends has had multiple Mercedes turbo diesels - all lowered and with big wheels. And he previously drove Porsche 924/944 (Still owns a 356). His wife drives turbo diesel as well...

My prediction is that within the next 5 years we will see a Porsche with turbo diesel engine - maybe not in the US, but in Europe. It will be a Cayenne, and the engine will be based on the VW V-10 that is available in the Touareg and Phaeton with 313 hp. These vehicles will start changing some perceptions - when a Cayenne turbo diesel blows away a 928 S4, Carrera, or Bosxter...

Hmmm..... so, c'mon Nicole... fess up.... was that you in the right lane, driving this Diesel Slug ?

It's a shame that we are so alow to accept things over here, VW has been selling diesel Jettas for several years and the only way you can tell from outside is the TDI badge on the deck lid.

If I were in the market for an SUV, I'd give this one alot of consideration based on the engine alone:

If D-C ever offers the Engine/trans from their Sprinter van (5 cyl diesel/5 spd auto) in the Ram PU line, I'd have to give serious consideration to trading in the current gas powered version.
