powerful engine
How about this engine in a locost? Would maybe need to slightly adjust the strenght of the chassis though.

I think I saw Chris Barry walking around in the crank case of something like that on Massive Engines on Discovery. I think it was in an enormous
container ship.
I thought turbines were more efficient when going for power that big... am I wrong?

Don't generally need the extra refinement (less vibration) and greater shp figures-for-less-space-occupied provided by a GT on a containder ship
as these advantages are outweighed by the higher initial cost. Big rock crushers like the one bookmarked further up are made out of less expensive
materials than yer average fan-in-a-can

I went on a US container ship heading for Felixstowe (I was with my neighbour, who was a river pilot) - while standing on the bridge of this immense
ship, I saw a little plate that showed the engine details...
single engine, 4 cylinder, reciprocating mass 100+ tons!
The thing about these huge diesels is that they use the cheapest fuel oil imaginable - it's like filtered crude. They have to heat it before
it's fluid enough to go through the pipes to the engine!

different tack but the same theme, for a while now i have been trying to find a large piston, have seen a polished example out of a spitfire plane,
looking for something about 1m to .5m across anybody any ideas!

Try looking in Yellow Pages for ship engine mechanics/repairers... they may have an example with, say, a small end gone that's no use to
them...

When I was in the Navy, the GT's had a life span chart, they had much shorter lives in the tropics, and using higher rpms.
The main problen with GT's is that you need a reducing gearbox as big as the avarage semi to bring the revs down from 32,000 to about 150 for
the prop shaft
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Now this would be a hell of an engine for a Locost. If my calculations are correct the
displacement works out at something like 113 litres!

Errr... the displacement is written further down the page.... 127litres
I love the idea about the axially shiftable cam shafts though..... now how could you make and axially shiftable ohc for a pinto, with 2 different
profiles ???

The Fjordline ferry that goes for North Shields to Norway has one of it's old pistons on display. I'd say it's between 30-50cm in
diameter and maybe 80cm tall. They cost several grand each so I'm told (my mum's friend is the manager of the UK side of the
operation).
I've no idea how you'd go about obtaining one though. Maybe contact the engineering divisions of various shipping companies?
