Ive been reading articles on carbs and tuning etc. Learning some before I get one.
I found this article on How 4 barrel carbs work. ARTICLE HERE
Within this article it quotes a formula for working out the CFM needed for %100 volumetric efficiency. The formula is as follows:
CID x max RPM / 3,456 = CFM
CID = 351
Whats the clevelands in xbgt's max rpm for this equation?
Divide that by 3,456 and you get your cfm figure.
This number determines what size carb you want.
Also, there is a choice between vacuum and mechanical secondaries. From what I read vacuum secondaries are better for everyday street use.
Then I just have to make a selection based on the above information to choose a brand?
Does all this sound right? Or am I not getting it?
