Quote: When would it be important to flow a carburetor? I don't mean to sound ignorant. I'm just trying to understand the purpose.
I can think of some.
1) Rating actual carb air flow 2) Gathering data to tweak a carb to make all the venturii flow the same and give the same booster signal 3) Improving carb air flow, comparing changes
Yep.
My primary interest for this round of tests was seeing what sort of quantifiable flow improvements resulted from increasing the venturi size. I know from on-track testing that "bigger" carbs that may show HP improvements on the dyno don't always translate to improvements on the track.
Gaining ~ 20 cfm going from 1.425" to 1.500" venturi looks like better potential for "real world" improvement than only gaining 10 cfm from stepping up yet again from 1.500" to 1.562", assuming this data is legit for the purpose of selecting the carb size for my 452.
