Weber does not rate its carbs on the basis of cfm -- with as many as 91 (13x7) different possible permutations of main and booster venturies within one DCOE bore size, which combination should the manufacturer rate?

Re: Total Flow Rating of Weber 48 IDA\'s
The total flow rating of all four I think would be a mote point. Each cylinder can only see one barrel of one carb. I would think that the maximum flow rating of each type would be useful - if a 48IDA can fit a maximum of a 44mm choke then the max flow of the carb with the 44mm choke installed would be useful.

ON 48IDA each barrel flow 330cfm with std horn and 42mm choke,with same choke and custom horn:345,with same choke,custom horn and bored to 51.5mm:362cfm.Noted size of chock don't affect serioosly flowing.All these tests are tested on superflow flowbench.
