Ignition timing
« on: August 26, 2019 - 10:27:49 pm »
So I dynoed my 512 last week. Ive always thought that more ignition advance would make more power, however mine seemed to make more power with less advance. We started out with 36 degrees, then 32 and made more power, and ended up making the most hp at 30 degrees. This is a 11:1 low deck 512 with Hughes hydraulic roller, Trick Flow 240s and a six pack on 91 octane pump gas. Does the ignition timing seem unusual to anyone else?

Not really, the motor wants what it wants and at least you had it on a dyno to figure it out. Imagine if you had stabbed it into the car, you would have never known. Each motor and combination have different requirements and like different amounts of timing. Bottom line is if it makes more power and is reliable with 30 then so be it.
