No but you could make a vague guess at it.
Combine it with the ignition map and you could get a little closer, add in some specific experience with the engine in question and you would get a little closer again.
Do a leakdown test so you can see a bit about the condition of the engine and you would get a little closer again.
Combine this with technical spec of the turbo, and the inlet temps etc and it gets closer again
So for example, if you gave someone like Stu who has a LOT of experience with cossies a cossie fuel and ignition map and leakdown data, im sure he could guestimate it very well.
BUT its still only ever going to be a guess, it would also vary based on cam timing etc too.
