why lean is bad

[SlowGT]

Hey jimberg

Could you help me understand this:

The same amount of heat is produced at 15.7 as at 14.7 as at 13.7.

Only at 15.7, there's not enough fuel to absorb all the heat, so the heat ends up in the pistons/rings, etc.

And at 13.7 there's an excess of fuel so the heat is more than adequately absorbed therefore giving a 'cooling' effect in the combustion chamber.

and if you're 'cooling' the combustion chamber, subsequent cycles will be losing heat from the reaction to the combustion chamber instead of using all the heat for the combustion process.

Is this enough understanding to be promoted to Grasshopper 1st Class? or have I missed the mark again?

Thanks in advance
Jared.

BTW, nice Vert. Dark blue w/silver is one of my favorite fox paint schemes. I see you've got a Lightning block in there. Do you know if all Lightning blocks have a roller cam from the factory? I've been leaning toward a 347, but I think a stroked 351W would be a lot healthier and beefier. Maybe in the 383-392 range. The only thing is, I've never seen swap headers for an SN95.
Thanks again.
