Good as place as any to ask this question -
My Uncle who later built engines for power boats (he is in the Michigan power boat Hall of Fame) suped up a Mercury for my Dad in the 50s that my Dad always talked about ( Dad raced it on Telegraph and of course Woodward)
My question: What is the Max number of Carbs that could be put on the engine? Because my Dad used to always talk about he could see his fuel needle drop in minutes!
I can believe that. When I was 16 my mom had a 73 Olds Custom Cruiser station wagon with a 454 engine. It literally got maybe 5 mph.
It was literally 1/4 tank to get to school and back.
“What is the Max number of Carbs that could be put on the engine?”
150 weed eater carbs
Check out the Munster Coach above and count the velocity stacks.
You'll find that there's 10 of them, one for each 1 barrel carburetor. On a V8 engine.
Weird, painful, and uncalled for, which I suppose was the point of doing it that way.
The real answer to your question is it's not so much about the number of carbs as it is about the total amount of CFM, (cubic feet per minute), of air the carb or carbs are capable of flowing. There is a realistic limit depending on the cubic inch displacement of the engine.
Too much flow = too little velocity = massive tuning problems.
Sorry, I know very little about the mechanics.
While in reality the max number is whatever the mad engineer wants to install, exceeding one per cylinder won't gain much for you.
Three two-barrel carburetors, two four-barrel carburetors, or eight single-barrel carburetors covered most racing setups prior to fuel injection.
