6 an High Speed Bypass Valve Incl X1 Thick & X6 Thin Shims
Product Information
High speed bypass valve, complete assembly. A high speed bypass is needed to obtain maximum horsepower because the engine will experience a loss of volumetric efficiency at RPM above the peak torque. At high RPM the inlet valves are open for such a small amount of time that the cylinders do not have enough time to completely fill with fresh mixture.
