Let's see Jay Leno stuff this in a car.

108,920 hp at 102 rpm:- This thing is barely turning - lets see it hit 6200rpm (only joking!)

Cheers,

I'm surprised turbines aren't a more effective engine choice for such large continuous power applications. Simpler design and likely more reliable.

I cant imagine changing glow plugs on this....How the hell did they torque down the head bolts?

I've spec'd these out for work a few times. They can produce insane amounts of tension on huge bolts that would be next to impossible to torque by conventional means.

they are also less fuel efficient and likely more maintenance intensive.

the only people who seem to use turbines are those that need oob gobs of power and big increases in speed, on demand, and damn the fuel bill. ie military.

I'm thinking those giant diesels turning at such a leisurely pace in those tremendous bearings are pretty damn reliable.
I'd love to know the assembly clearances for those monsters. Unless there are wicked amounts of oil pressure and volume I think they'd need to run clearances pretty close to what we are accustomed to. How would you like to be the machinist who takes half a thou too much off THAT crank?

Dude! What do they use that engine for?
