Hot running 440 60" over

plain and simple they create more heat ...

Yes....I understand....but....WHY???.....what causes the heat gain???? greater parasitic losses?....circulated coolant volume low? Just curious......

Your link abt. vpraceingfuels.com would not connect.....spelling??? Thanks
BOB RENTON

You are correct. Try vpracingfuels.com. Sorry about that.

Higher compression + more combustion (cubic inches )+ more fuel/air = more power. More power = more heat, yet the cooling capacity of the block via oil and water circulation remains the same (unless somehow upgraded).

The cooling system is designed to handle the WASTE HEAT of the process.....the other factors enter in the production of energy conversion OR HORSE POWER to do work.....

Post #43. Higher compression on it's own reduces heat. The a/f mixture takes longer to burn with low compression engines, so the surrounding metal absorbs more heat during the combustion process.

Maybe, but that was not the point. Just saying... overall, more power = more heat. If the cooling system remains the same under the circumstances of added power it has to but to the task of eliminating that additional heat, and if it is so, more heat will be released via that system.

Nope.
If I turn the dist to retard the ign timing, the engine runs hotter. Same engine, same cooling system. Engine is now inefficient, same as when you lower the comp ratio.
