horsepower

[apache]

6300 bhp, 171 litre, 9 turbos, can ya guess what it is yet?

Locomotive engine?

[apache]

ok too easy

[pitsnow]

36.8 HP per litre? That’s crap for a turbo engine, even diesel.
How much torque though?

[apache]

1 x Cummins QSK19 of 560kW (750hp) at 1800rpm per car, dunno about the torque

[Pigeon]

It's not that crap given the rev limit of 1800rpm... if it went to the usual car limit of 4500rpm, all else being equal, it'd be 92bhp/litre. But you have a different set of priorities when speccing an engine for a train.

Cr@p how dare you, I used to build the high speed train engines.......RP200 Paxmans. 12 cyl roughly 2k BHP, but only .4lbs/bhp/hr fuel consumption........not bad for a 72Litre engine.
The prototype 18cyl versions we built topped out a 6k BHP......... and this was 15 years ago............

Well I built power plant for a living. So maybe my perception of power is slightly out of tune. Our gas turbines have an output of 260MW each or roughly 348’665 HP
That’s in single cycle without heat recovery generator. If used in combined cycle, those units produce 400MW. And than there are the big steam turbines used in the nuclear and coal fired power plants. 1360 MW per unit. And those are more than 20 years old.

Different technology though, although the figures look impressive.....

kevin.

who dosen't miss the smelly diesel life one bit.
