Flow Quick.

[Zane Bates]

Great site guys and some good info.
First question.
I did my bench with a Audie Flow quick and was wondering if anyone else has used one.Mine is repeatable but if you calibrate at 80cfm at 28 inches it will read almost 40 cfm low at 300.I borrowed a calibration plate and calibrated it at 244 cfm and now with the 80 cfm calibration tube it reads 90 cfm .Audie says 5% error max .

Also What kinda of error should I expect out of Pitot system compared to an Orfice style.I just woul love to be in that within 5% of what the heads are supposed to be.
I got heads that flowed 280 cfm and my bench says 244.
