FE Technical Forum / Re: Timing Curve With Vacuum Advance Distributor
« on: March 12, 2014, 10:43:27 AM »
The reason for this post was to ask, if my total initial + centrifugal advance is 38* while I cruise at 2800 RPM with 20" of Vacuum causing the vacuum advance to providing an additional 10* of timing (bringing the total advance to 48* at cruise) is this going to be a problem?
And if it is, should I start to back out total centrifugal advance? initial advance? or an equal amount of both?
Even if I I was running with the total timing (initial + centrifugal) to 32* at 2800 RPM, the vac advance is going to put it at 42* total. Now the vacuum advance is going to start backing out as I tip into the throttle or drop out completely at WOT, is that what keeps you from detonation.
Is this how the vacuum advance works and are those realistic total advance numbers you see with a vacuum advance distributor? ww
