Less of the fuel being burned would give lower EGTs and lower cylinder pressures. The lower cylinder pressures would put you further away from detonation limits, which would allow more ignition timing. The extra unburned fuel would actually act as a chemical coolant, which is what rich mixtures are actually for. The extra fuel providing extra combustion cooling and the increased ignition timing could provide more horsepower from less fuel actually being burned. |
A lot has been covered. I did actually re-read the thread. There are some lose ends to tie up.
I threw this post in to get you guys thinking. I was exercising my imagination a bit. I don't actually think this is what is happening.
