Diamond like coating......
I was in an engine lecture the other week learning about DLC, F1 are testing engines that dont use oil as the oil causes a type of friction, (like when people get their cranks knife edged to cut through the oil better) reading race engine and mags like that it seems they can get engines to run almost 7hrs without oil, so surely if we used DLC on Cosworth engines, maybe with a lower grade oil? then we could see quite a gain in power, as friction is on of the most power absorbing factors in an engine.
then also there is honing, I think Audi did this first, not quite sure though, and its a bit old skool now, but the most wear in a cylinder is around TDC as the oil the is pushed up the cylinder by the piston breaks down at the momentary lack of movment causing the wear, so if you had just that part of the cylinder honed it would keep the oil up there causing less wear at TDC.
anyone got any views?

Its pretty cool stuff, we worked out that the pressuse one the piston as the mixture comes in is near 9.4 tonnes and the side thrust is roughly 2.7 tonnes, amazing learning about real f1 stuff, we worked out that if you make the con rod longer then the side force as the piston comes down will decrease due to the angle at the crank being smaller. but F1 pistons only use 1 compression ring and 1 oil ring, and they go to 0.1mm of the squish area at TDC. awesome build quality.

dont cossie engines only last about 7 hours anyway!? 
youre doing motorsport at uni then im guessing! wouldnt mind doing it but i worry about there not being a massive ammount of decent jobs available to graduates? only thing that puts me off really.
