sorry if im argumentative, but im drinking and my redneck is coming out... lol
are we talking about modern engines or the 500 caddy? there is a huge difference. higher engine temperatures have an exponential effect on metal expansion do they not? if so, then bearing clearances would have to be larger for the hotter running engines which could mean nasty knocking sounds on cold running. a 50/50 mix of ethyl-glycol coolant and water at 15psi boils at around 260, which i believe was posted above as the temp at which normal oil breaks down. so why is there any need to have your cooling system stronger than your weakest link(oil system)? a redesign of radiators, coolant temp sensors and thermostats would have to be done. not to mention the fact that on "modern cars" the emission monitors/readiness tests wont run with an intake air temp higher than 170. that value will be affected by the increased engine temps. i guess the makers could start installing intercoolers on all the cars... and last but not least, as it was stated above increased engine temps arent good for power output. i guess its up to the consumer whether they want a 10% gain in fuel economy or a 10% loss in power output.
IMO... if it were possible to do in any way, one of the manufactureres would have been on it like stink on shit a long time ago.
sorry if i pissed anyone off, have a happy turkey day if you are fortunate enough to live in the greatest nation on earth
