Designed to upgrade the existing turbo actuator, the Forge Actuator range are available in polished billet alloy for durability and optimum appearance.The Forge Actuators are available to fit a wide range of popular turbo applications, and feature uprated internals to cope with tuned and performance engines. Actuators are a mechanism for allowing programmed levels of boost pressure to increase when the throttle is opened, maxmising turbo system performance. The Actuators can control the amount of boost in a similar method to boost control valves, but are generally more accurate and incorporate higher grade internals to deal with a greater range of turbo set ups with optimum reliability.The Forge actuators are designed to incorporate the facility for increased strength springs for higher tuned engines, with the standard types which are supplied, suitable for standard or slightly uprated systems. The Forge Actuator range is designed to be fitted with a turbo system of equal/comparative p
