How do you figure any of this? a wastegate is not for a huge power application, wastegates are used all the way down to 7 psi.... it is for CONTROL that is what a wastegate is for. a turbo needs some type of control for boost, whether it be furthered with VVT technology, but all this is a "ceiling" for the turbo. not running a wastegate would not have anything to do with lag, but a turbo could build a ridiculous amount of boost and kill itself, or none at all depending on the application. ive seen both happen.paul1987 said:To clarify the reasoning on the necesity of a waste gate, If you had a turbo on your truck that did not need a waste gate, it would be small, you would have very minimal boost and a huge turbo lag. They put larger turbo's obviously for more power and to eliminate lag. If you did not have a wastegate on it, you would have a whole lot of spare parts laying around. Like previously posted, there are safe ways to make more power.
