I guarantee you the DA at Numidia was way higher than the DA at Atco...there's your ET gain...

2 big ones from Numedia to Atco, at least.


If the results don't match the theory, change the theory.

That could very well be. Just to do it I have flowed heads as they came off the car with carbon on the valves, and then flowed after cleaning carbon. Big difference in flow, especially the carbon on the backside of the valves which usually will not burn off under hard runs. I would try some good carbon cleaning chemicals, like BG products or GM top engine cleaner.

Do you have a weather station ?

DA is just one part of it
Water grains are very important also
