There are many companies producing great 44-46mm wastegates these days, however Forge just dropped off a prototype piece for testing that puts a new spin on boost control. This particular wastegate is unique in the fact that rather than using the traditional valve and diaphragm to control the air, this particular unit uses a piston based design. This allows for easy rebuilding and less worrying about a torn or damaged diaphragm. We hope to test this prototype gate in a few applications over the coming months, and if all goes well Forge will offer a production run for general consumption.
