[quote=Maxwell]This sounds really lame, but I can't discuss how he does it because he's the only guy in the USA that can test to such fine acuracy. quote]

Well I don't see another way of measuring fuel passed - counting molecules, use acid and titrate to determine the volume or just use an accurate measuring cylinder, if the cylinder is of a small enough diameter the accuracy should be quite high.

Don't know much about accuracy in injectors but what is the accuracy are you talking about? If it's say +/-0.5%, thats +/- 3.5cc per minute at full flow - how accurate and the injectors be set up?

Got me thinking anyway.

Anyway Merry Christmass all.
