I was working in a large engine dyno cell today and had to share a pic of the engine output at idle. just chugging!!
Not sure what power this one makes at full load, but I think some of them are up near 6000 Hp at about 2500Rpm flat out.

Boost!!

272kw is 365hp

9.85 @ 145mph
202mph standing mile
speed didn't kill me, but taxation probably will

Yep, that's about right. Not a bad output for idling.. I think it was a 60 liter diesel generator engine. A small one!

If it's a generator set rated rpm is usually 1500 or 1800 rpm to give 50 or 60 cycle AC

This was just an engine, i think they either get supplied as an engine for boats, pumps locos etc or built up into a Genset which then gets commissioned in its own right. On these tests they are partly to prove the engine works and partly to ensure or demonstrate that they make the specified power values. i have only ever seen them running through full RPM profiles, although i think they only go to 2000 or maybe 2500Rpm, but i don't know much about the test profiles.
They are mostly unspectacular as the soundproofing is pretty good, but when they cycle through a full load test you get a very good sense of the power coming through the floor and walls of the building. I recon it must be possible to measure Hp through ripples in your tea cup..

I agree! Before the days of H&S standing in the cell with a V12 making 1200 bhp next to you was mind blowing.

I think your spot on with health and safety. Sometimes it's good to feel a bit of danger!! The sobering thing on these lumps is watching the cranks and cams being fitted with a crane! Even the drive shaft to the dyno is 500kg. Its bad enough when something small pops put of a lathe chuck. Imagine one of these bouncing round the walls *smiley*
