Thanks for all the input everybody....
From past experience, all the 'tools' measure their own way
i wonder if anybody has tried to sit at the local university weather station and try to calibrate??
We were always careful to use the same gauge during dyno jetting as the one that would be used at the track. a benchmark was established...didn't really matter what the number actually was.We had a single face / analog gauge that was nearly as big as a gallon paint can. It rode in a beautiful mahogany or
? wood case and never never never flew!
I understand the math, but reading a single number on the gauge and cross referencing a jet chart that is duct taped to the dial's cabinet seems easier / fool proof in the heat of it!
All that I can find to replace it are small 2 1/2 inch face dials at ~$125. Anybody have experience with these type and price point? or another suggestion???
