Message In one program I added just one more degree of timing and there was a 5hp gain at the wheels.

In my own car I have advanced the timing to a total of 33 degrees (which would be like you taking your static timing up to 24 degrees) on race fuel. Granted, I only increase it in the high load section so it doesn't detonate at the lower loads, but going from 24 degrees of total timing (which is what I run on pump gas) all the way up to 33 degrees on race fuel takes about a half a second off my ET's, consistently, without doubt. There is a good deal of power in ignition timing. The only thing you have to listen for is detonation. If you advance it too much, it will detonate. EGT's wont rise either, in fact, they will tend to drop. EGT's rise when you retard timing simply because the ignition starts so late that when the exhaust valves open, there's literally flame coming out and still burning. Advancing the timing puts that energy into pushing the piston down rather than wasting it out the tailpipe.
