[V8] Ign Question to the V8 Guru's out there

[Andrew Schlueter]

When I advanced my cam timing and forgot to plug that in, it deff had a
lumpy idle then smoothed out soon as I connected it. Again, I am about
to tomm disconnect to feel the results. Sounded good though. Hmm...if it
retarded the ignition, that would most deff give more torque.

"What happens when we retard the timing?:


If you RETARD ignition timing down from -30 degrees to -26 degrees, you
start the combustion event later and finish it later by 4 degrees. The
rise in cylinder pressure starts and finishes 4 degrees later.
Everything is shifted to the right along the X-axis of our graph.

So with a delayed spark or "retarding", there is less time for the
expanding force of the combustion to work against the rising piston
(piston has to work less harder) and the peak cylinder pressure occurs
at a better rod to crank angle to help turn the crank and make more
power (i.e within that ideal +12-25 degree ATDC range)."

with advanced cams, chip, this might be kinda nice as long as you do use
91+ octane. Top priority Sunday!

With this disconnected, your timing will be retarded
