Carburetor CFM Calculator — Frequently Asked Questions
Q1 Why is an oversized carburetor harmful on a street engine? ▾
Overly large venturis reduce intake air velocity at low RPM, causing weak fuel atomization, sluggish throttle response, and poor low-end torque.
Q2 Where does the 3456 constant originate? ▾
1,728 cubic inches in a cubic foot multiplied by 2 (since 4-stroke engines fire each cylinder only once every two revolutions: 1728 × 2 = 3456).
