Good day everyone
Im looking for a dyno spark advance curve for model Ts
That would be a graph with spark on the vertical axis and rpm on the horizontal axis at maximum torque.

Is your engine and ignition system stock? If not, how is it modified? Correct spark timing in any particular instance depends on a number of factors. Stock torque maximum is around 900 RPM. A stock T engine can take a good bit of advance at that speed using pump gasoline.
