Cool Peterbilt!"

6V92's are dog's requiring massive maintenance. The Coast Guard had to supercharge AND turbocharge them to get any useful power. A N/A 12V92 is probably a pretty poor performer for the size/weight. Looks cool.

Every 2-stroke Detroit is supercharged and many are turbocharged. The supercharger (nee blower) isn't for power. It's for normal operation.
Ever wonder why superchargers are rated such as 6-71 or 8-71? Because that's the Detroit Diesel engine that it originated on.

I see the blowers in the pic finally. They look tiny when they're chromed.

The rear suspension is unique. (At least to me)

Cool, I did not know that.
As for why American's don't "get" diesel cars....

Actually, as long as you dont mind driving it like you stole it, Detroit 2 strokes make a ton of power, are cheap to run, and the sound cant be beat.

I had no clue the peterbuilts were two stroke diesels.. is that why they sound so smooooooth?

Cummon Jay, can't you afford to give us a video without making us watch a priceline commercial?

Not his fault....all the content is hosted by Leno's boss, NBC. It seems like the network could better target the ads, though, and make them automotive. There are a few ad-free build pics of the project at the blastolene site.

I loved the Olds diesels...
We rebuilt my Hurst Olds 350 using all of the block and crank from one. Ran great until I squirted it with one too many shots of n2o.

Not a car, but I always liked the Monster Garage diesel trike. The link I had for it on Discovery no longer works. But the one below will give you an idea.

Old 2-stroke diesels with the pump turned up will blow flames out the stacks at speed.

Not all Petes are 2 strokes--just the Jimmy Diesel (GM Diesel, or Detroit Diesel) equipped trucks. In the past, you could get any engine in any truck. Now (or at least very soon), you can only get a Detroit Diesel in a Freightliner (or other Mercedes-owned) truck. Your Volvo or Mack only comes with a Mack-built motor. You won't even be able to get a Cat engine in an OTR truck by 2010.
Of course there are a few instances where this isn't exactly the case, but for the most part, the truck manufacturers have aligned with the engine builders.
Detroit Diesel 2-strokes have a strong power band across their narrow RPM range. They're especially effective where torque requirements quickly change, such as when a generator immediately kicks on. The power strokes (which happen twice as often as in a four stroke) prevent the engine from bogging down.
Emissions are dirty, though, as the blower often blows unspent fuel out of the exhaust. Like what Sleifan said, get it hot enough, and you'll get a good flame show.
If you're a real motorhead (like most of us are), google how a Detroit Diesel 2-stroke works. It's so simple, it's cool.

Not really. In the past, you could get most engines in most trucks. Some companies have slimmed down their engine offerings drastically, International and Volvo/Mack do this a lot more than the other guys. Peterbilt, Kenworth, and Freightliner/Western Star use lots of engines. For example, in current 50-state Freightliner chassis you can get Detroit Diesel, Mercedes-Benz, Caterpillar, and Cummins engines. Paccar offers Paccar, Cummins, and Caterpillar engines. Cat's getting out of the on-road stuff, so of course they're going away next year but Cummins is still in the engine business without being (or being owned by) a truck manufacturer.

I want a Delta 88 so bad to put airbags, 20s, and LSx into for a cruiser. I just want to be a G, that's all.
I'm sure that thing is a brast to drive, diesel power is pretty interesting on a hotrod as well.

Most buses were powered by Detroit two strokes into the late 80's. The superchargers we needed because as two strokes there was no intake stroke to fill the cylinders so the supercharger was there to force air into the engine. When I started at the bus company we still had a few of them left. I tried to get one every night. I liked the sound of them echoing off the buildings.
