PLUMBING, ADJUSTMENT, AND OPERATIONAL NOTES.<\/span><\/p>\n

The Torque Valve is a bypass which opens and closes in a pressure range of\u00a0approximately 9-55 PSI.<\/span><\/p>\n

The primary purpose for the Torque Valve is to bypass fuel and lower the system pressure\u00a0when the engine is at Wide Open Throttle and the engine RPM is lower than the point where Peak Torque occurs.\u00a0 When the RPM is below the peak torque region, the engines volumetric efficiency is lower and the required fuel is reduced.\u00a0 Excess fuel can cause a loss in lower RPM torque output and cause the engine to falter during hard acceleration.<\/span><\/p>\n

The Torque valve holds a \u201cJet\u201d in the shuttle valve, (reverse flow poppet), which controls the bypass volume and also the force exerted by the flow to move the shuttle and close the valve.\u00a0 At any constant flow rate, a change in the jet diameter will create a change in the applied force to the jet and the corresponding shuttle.\u00a0 Example: Changing to a smaller diameter jet will decrease the flow at a given RPM and increase the pressure \/ force applied to the shuttle.\u00a0 The shuttle in this example will now close at a slightly lower RPM.\u00a0 The specific change in the pressure can be calculated by utilizing the formulas shown in the \u201cOrifice Theory\u201d on page 202 of Kinsler Handbook (Click Here)<\/a>.<\/span><\/p>\n

The \u201cOpening\u201d point, or initial bypass, of the Torque valve is controlled by an idle check valve located at the inlet.\u00a0 The idle check valve is intended to maintain the idle fuel pressure of an existing system so that the barrel valve will not require adjustment when the Torque valve is installed.<\/span><\/p>\n

The \u201cTorque Valve\u201d must only have clean fuel passing through it and back to the fuel tank.\u00a0 The valve is plumbed in parallel to the main bypass and should not see any back-pressure on the return flow path back to the tank.\u00a0 We recommend that this valve be plumbed via a separate hose to prevent changes in the return flow pressure that might be caused by any other bypass valves.<\/span><\/p>\n<\/div>
