What would the customary application be for such a plant?

According to the article: Instead, the massive 95-liter engine was built to power mining dump trucks, the largest locomotives or generators with enough capacity to power 3,500 average houses.

If it won't fit in my Jeep Cherokee I'm not interested.

Just got to boost the front suspension a wee bit...

8,000 HP in a smaller and lighter package. Engine life is a problem.
I've rebuilt a few of the big inline Cummings engines. But none near as big as that one.

Now all Hutch needs is a Camry to put it in....

So, what kind of mileage should we expect?
stay safe.

1 ton of frieght going 500 miles on 1 gallon of fuel.

Hell, we can shoehorn that thing under your Jeep hood Hawk. Never say never! =D

Yeah, but the problem is that those have the habit of occasionally undergoing a spontaneous rapid disassembly... :)

Maybe so -- I forgot there's a custom spring shop a few miles north ...
Might need to stretch the front frame ears a tad so's we could move the radiator forward a bit. And install a periscope.

1.5x the weight, 75% the power, runs on something other than nitromethane, and lasts a hell of a lot longer than 5 seconds at max power.
:)
Though, if you really want power to weight, the SSME hydrogen turbo pump is 70,000+ HP, and doesn't weigh much more than a top fuel big block, and has 100-200x the lifespan.

Pratt makes those, right? Not sure if most folks could use a LOX engine for most terrestrial activities. Or am I thinking of the wrong engine?

PW-rocketdyne now. Your thinking correctly, but technically, you could make a liquid-air hydrogen cycle that could use it or similar with kerosene. Power density on turbomachinery increases with pressure, and 4kpsi pressures make an engine REALLY small.

I figger we'll just put wheels on the engine and drop the jeep body on top. ;)

GM's Electro-Motive Division (EMD) produces diesel engines that displace over 1000 cu. in. per cylinder, some of which produce 6000 hp. They do run dirtier: not Tier 2 compliant.

I used to work on a 12 cyl Fairbanks Morse generator that was taller than I was. Never considered how many horsies might be inside.

The Cat equivalent is the 3516 or C175-20.
3500 is the series of the engine, or platform. The last 2 digit represent the number of cylinders.
3508 = 8 cylinder
3516 = 16 cylinder
3524 = 24 cylinder
C175 is a new platform introduced a few years ago. 175mm bore. Again the last 2 digits is the number of cylinders.
C175-20 is a 20 cylinder.

I got to visit this Finning dealership in Antofagasta, Chile. That was an interesting trip. While taking a tour of the facility, they showed me this dyno room. At the time they weren't testing an engine though.
Where are these size engines used?
Marine - large pleasure craft, tugboats, small commercial shipping, fishing boats
Power generation - land based continuous and standby generators for large commercial and industrial buildings, and ship based generators
Industrial power - large air compressors, gas and oil line compressors/pumps, oil drill platform power
Heavy machinery - 797 mining trucks, mining shovels, EMD locomotives

How long do these engine last?
Of course I am biased, but I believe Cat is the industry leader on this aspect. The hours till overhaul on this size engine is in the range of 20,000 to 27,000hrs. For a mining truck running 24hrs a day 7 days a week, that is about 3 years of continuous running (stopping only for refuel, oil change, filter change, driver change, and other maintenance).
Cat's 3500 and 3600 engines are assembled in Lafayette, Indiana.

The only other thing it can do is turn the pistons and con rods to slag so the outcome is about the same no matter what.

Yes, but the fuel tank is a bit unwieldy.

Screw the hp - the torque is 12K ft. lbs.! Dam!

SSME turbopump is 10,000 ft-lbs...at 37,000rpm, not a measly 1600ish :)

Yes, but is it also ~45% thermally efficient and last 20,000hrs of continuous operation at 100% load?
-
i wonder what they sound like under full power? when working for a small airline i had the oppurtunity to work on the p&w r-2800 engines. 2500 hp. when adjusting the carbs under load your whole body felt the power! kind of an adrenaline rush.

No :(. Only about 15 minutes
