Fred - Ask a little, learn a little, teach a little!

I remember seeing exhaust manifolds that were almost glowing red hot, and remember being told that the motor was running way too lean. Thats how I connected increased temp and lean. I hope I got it right!

Regarding the other part of your question - can engine power be linked to kilowattage or the sort - yes, it can. The idea of torque and horsepower was developed by James Watt. He was a British inventor whose claim to fame was the steam engines he built. Since horses did much of the work at the time, he needed to find a way to relate the work his steam engines did to the work a horse did (Horsepower - I know you saw it coming!)

Anyway, he came up with a formula to figure out horsepower - torque times rpm, divided by 5252 equals horsepower. 5252 is the number he came up with based on his experiments, and is a constant. Whats interesting here is that no matter how bad of an engine or how small of an engine you are building, horsepower and torque will always be the same at 5252 rpms!

The little I learned.
