![]() ![]() Manual boost controllers are simple, cost effective ways to increase boost. These are mechanical devices that are set manually and have no feedback and are not connected to the ECU in any way. Starting with one of the simplest forms of boost control, lets look at a Manual Boost Controller. Boost pressure can be bled off in a few ways, using a mechanical bleeder type system with a needle and a seat, a small opening or bleed hole, or the more reliable and accurate way using an electromechanical solenoid. ![]() Think of this as tricking the wastegate as to what boost it's seeing. This in turn delays when the wastegate will start to open and control boost. In order to get more boost than the spring pressure in the wastegate actuator, pressure needs to be bled off or blocked from the hose going to the wastegate actuator. Part 2 of Boost Control Systems Explained will hit on the most common ways of doing this. This is done by using different methods to change the boost signal getting to the wastegate actuator. In both setups, its possible get more boost from your turbo, than the wastegate spring pressure. Some of the diagrams in Part 1 were common items found on stock turbocharged engines, and some only found on aftermarket turbo systems. In Part 1, we describe the basics on how your boost control system works and the components involved. How do you get more boost than the spring pressure in the wastegate? ![]()
