Does a bigger carb make more power? What's thelimit?
Demon Carbs responds: Larger carburetors can make morepower on a dynamometer, but this can also result in slower accelerationand lower efficiency of fuel atomization. Generally we find that you'rebetter off leaning towards a slightly smaller carburetor than a largerone, as it'll operate more efficiently and provide better accelerationfor the vehicle.
How do I choose the right size carburetor for my engine?
Edelbrock responds: A simple formula can assist youwith this. Multiply your cubic-inch displacement by the maximum rpmlimit and then divide by 3,456 to represent the volumetric efficiency.The result is the amount of cfm the engine requires at the maximum rpmlimit.
Example:
350 ci x 6,000 rpm = 2,100,000
2,100,000 / 3,456 = 608cfm
A 600-cfm carb would would be sufficient.
dunque ho sostituito i parametri,con quelli del Pontiac 400(T/A) 400 x 4000...ecc.ecc ne ? uscito quasi 500Cfm..........DOMANDONA...perche il POntiac Monta un 800CFM?
A voi la palla.....anzi il carburatore
