Classroom question. Just for my curiosity.
Does not relate to a particular engine or car, but if it helps lets use my engine.
1916cc, 8.7:1 CR, W100 mild cam, 009 dizzy, electronic ignition, twin empi kadron style carbs.
My mind has been working overtime trying to figure out something.
I have static timing at 8degrees. Engine runs.
Its going to local mechanic so he can set 32degrees at 3,000rpm.
Then I can get a proper tune in the coming weeks…
Question, is there a calculation for static to dynamic timing conversion?
ie; 32 @3000 = 18 @static. (Just random figures)
Cant be a straight forward relationship…. can it?
I think that engine build specs and performance must affect timing adjustment capabilities.
I have googled but getting confused.
Thoughts,
Then there's the build quality variation...could be anything.
