However it is managed by a vacuum tank that is connected between the TVIS actuator and the manifold. this tank has a one way valve on the inlet side which shuts as manifold vacuum decreases therefore maintaining a constant vacuum to the actuator. Between the vacuum tank and the actuator is the TVIS VSV, once engine speed of between 4000 and 4500 rpm (depending on engine load) is reached the VSV allows atmospheric air to enter the system between the tank and the actuator causing the spring loaded butterflies to open. This is necessary as manifold vacuum fluctuates and becomes nonexistent once boost pressure is reached. Therefore this system is deisgned to have the butterflies closed under 4500rpm and open above 4500rpm regardless of manifold pressure. [Report message to a moderator]
