These spacers maximize airflow through the carby & enhances air/fuel distribution for more torque & HP. Part throttle performance & distributrition are improved by redirecting the flow pattern created by the partially open blades & gradually reducing the velocity of the air/fuel mixture, helping to reduce fuel seperation as the mixture enters into the plenum to allow for a smoother transition into each runner. W.O.T power is increased by the increase in flow produced.
DYNO TESTING ON A 393 c.i WINDSOR SHOWED AN IMPROVEMENT OF 16.7HP & 12.8 FTLBS FROM FITTING ONE OF THESE PORTED 4 HOLE 2″ SPACERS.
