Make it more clear for you, Formulajones.
Until Barry Grant and others used a different test pressure point, in their advertising claims, to dupe the average carb buyer into thinking their larger rated carb was "better" Holley, Carter, Weber, Rochester, Autolight, and others used the agreed upon Carb Test Point of 20.4" of water in their flow stand testing. Even before World War II.
CFM Ratings mean nothing if you do not use the 20.4" of water test point.
That is MY point. If you use a test point other that 20.4" of water then you get INCORRECT numbers. And do not say the larger carbs today require the higher test pressure number as in World War II Holley was building carbs (AND TESTING THEM) that flowed over 3000 cfm per carburetor at 20.4" on aircraft engines. I do not see anyone selling 3000+ cfm carbs in the aftermarket tested at 20.4" of water.
