Been pondering this for awhile anyway...
So, correct me on this if I am wrong...
1. Fuel atomizes better when it is warm correct?

2. Fuel can burn better when it reaches a better atomization point correct? (you get the point)

3. Oil performs better and last longer when it is cool correct?

Reason I am inquiring about this is, on the GE turboshaft engines, they have whats called a liquid to liquid cooler. A tubular shaped housing is used in this design. Much like an oil filter. Instead, warm oil is passed into this housing where a fuel line is zig zagged inside. Basically, the warm oil warms up the fuel and at the same time the fuel cools off the oil.

Would something like this work on our cars? Or is this type of application not justifyable or perfomance gainable? What say ye?

acutally you want the fuel in the vhehicle as cold as possible....racers have been cooling there fuel for years for a better burn

Not really a better burn, but a colder cylinder which = more boost or timing which = more power.

You have to remember that although SuckSqueezeBangBlow is the same everywhere, the way it'* accomplished is way different in jets. For one, the hotter jets get, the better they run, within the limits of the materials they're made of. Piston motors are actually very sensitve to heat, and run well only in a narrow range.
