    before you go asking it for too much power... remember all engines are just heat pumps, more power means more heat.

    look at how a blast furnace works and do a quick comparo between gas fired ones and oil (diesel) fired ones in particular the temperatures they can be made to reach.

    look up the melting point of aluminium.

    without getting into the lpg fumigation argument or the whole convolutant messy "stress of combustion pressure" issue thats inherent with internal combustion engines, if you feed the engine enough air, and enough fuel and wring it hard enough the temperature inside the combustion chamber will go high enough to beat the the thermal conductivity of the ally in the pistons and the head.

    Once that happens....

    there is only so much power you can make from ANY engine, once you reach the limit of the metalurgy in terms of temp and pressure you're forced to go for more size.

    BMW are running 200kw and 600Nm from 3 litre production diesels.

    the Transit Vna Puma pomms seem to be topping 200klw with a chip and bits.

    Hi Dougal,
    Isn't a Land Rover 3 litre TDV6 about those numbers?

    I have seen a few claimed 200Kw for chipped TD5's, but never any evidence backing it up.

    I'd guess Lara with his stroked and stoked TD5 ?

    [edit] just found some figures on Pirate, Lara claimed 260HP and 430lb/ft of torque, but I suppose it's really 2.8l now
