A couple or three months ago, there was a discussion regarding voltage drops while starting or the engine might be kicking back. I believe the discussion may also include that most of the people experiencing the voltage drops and/or kickbacks were using the Holley HP EFI System. During the discussion, it was suggested that maybe the crank timing setting could be set too high that may be causing a kickback rather than a voltage drop. Also, this discussion included some may be experiencing actual voltage drops.
In any case, I am posting this because I also were experiencing possible kickbacks and/or voltage drops and I am using the Holley HP EFI System. I made sure that my grounds were good and also I have a second ground from the battery directly to the engine block along with a ground strap from the chassis to the engine block. The primary ground cable runs from the battery to the chassis and my battery was relocated to the back of the car, in my case, in the radio module compartment behind the passenger seat in my C4 Corvette.
Yesterday, I had the cranking timing setting set from 15 degrees to 5 degrees. After the setting was set to 5 degrees, so far, I haven't experienced any kickbacks or momentary drag in starting the car. I know that at this time of the year I won't be able to experience what I would normally experience in the summer time when everything is extremely hot and just coming off the autocross course and go and try to start the car a few minutes later until the weather gets warmer. But, so far, so good.
At this very moment, I do believe that my 15 degree cranking timing setting with a 12.25 compression built engine may have been the issue with the momentary drag in the starter. We will see when the weather gets warmer.
