You ain't kiddin'... even with the turbo, Moller was more than .60 slower at Bristol than zMax. I was at Bristol for the K&N Spring Fling a few weeks ago, and was about .70 slow just in the 1000'!
In similar air (DA and correction factor), Farmington Dragway (which is around 1100-1200' physical altitude if I recall) was still .15 quicker than Bristol in the 1/8th mile alone. I made a jet change at Mooresville the following week and found .05 or so.... but not .50.
