Gunner, I would like to see what you have. The "delay on make relay" was about $30.00. I have been building engines since the 60s and have found when engines go they have damage in varying degrees depending on when they were shut down. It all comes down to sooner warning than later. Gee, there must be some reason planes and expensive boats have low
oil pressure warning buzzers. No question during high rpms if you lose pressure there is not much you can do. It comes down to the odds of when it happens.
I think it has merit so I'm putting it in my car.
