MagnaFuel's custom-machined Anti-Reversion Plates (shear plates) keep your carburetor flowing at or beyond its CFM rating by reducing intake reversion at high RPM. These plates help prevent airflow reversion by redirecting the hot gasses that can rise into the intake manifold as the intake valve opens and the exhaust valve is still closing. These re-directed gasses can then help release and atomize fuel droplets that sometimes stick and drip down the carburetor bores. If you run aggressive cam overlap, without MagnaFuel's Anti-Reversion Plate, these hot gasses disrupt the cool intake charge, reducing flow, dampening the carburetor booster signal and creating unwanted turbulence.
