Boost control wastegate

01 Mar 2006 Boost control wastegate

The supercharger needs some method of boost control. Originally, this was going to be electronic, but for a variety of reasons we’re going with a manual boost control, or wastegate.

The boost control will be next to the throttle, on the mixture lever.

When I move the throttle back, the red lever will move back too. If the throttle is wide open, I can move the boost control fully. The idea is to make sure that if I chop the throttle, the wastegate will open too.

Here is a view of the mechanism that hooks up to the wastegate.

Here is the big cable that controls the wastegate.
