That is exactly what I have 1781 carburator engine with 90bhp. And my
Audi is Quattro. Fortunately I have service book of this car and I can
say that engine is original.

No. This is the way how to avoid all extra dates like aerodynamics. When
wheel makes one turn it makes a path which is easy to calculate. Then it
is necessary to reach max rpm at the straight gear and calculate how
many turns wheel does per minute. Done. But I see that with my rare
combination I will newer get this data unless directly from Audi GMbH :-(
