I'll admit it may not be well worded - you try typing with a seven year old pestering you!

Can I spot you two three-and-a-half year olds.

As far as the second question goes, for diesels at least, it is possible to get exactly the same power and torque distribution over a wide range of capacities, simply by increasing boost and fuelling.

Its not really that important though john. It just read as if to say you've got to have a heavier motor to make more power, but a smaller motor can make the same power as a bigger one.

Has a little to do with the bush work the vehicles do, easy to break these auto's with stock engines and little tyres, if worked

The ZF 4HP22 was a designed as a car transmission, used in Volvos, BMW's, Jags and a few others - some were fairly powerful eg 7 series BMW and Maserati but a Landrover is probably its toughest gig. Landrover did fit a bigger sump which was a good thing.

Thats a fascinating engine John! Its interesting as the very basic design concept reminds me a lot of the Sarich orbital engine - obviously this is a significantly improved design of a multi combustion cycle though compared to that and the wankel motor, but I hope it doesn't get pushed underground in the same manner. Something like this has the potential to open up so many possibilities in vehicle design!
