How do I?!?! this wastegate is confusing.

Okay I took it apart, Its really simple, just a huge spring with a diapragm.

The piston pushes in now, but it takes a bit of force, like two hands of force.

does that seem right for 8-12 PSI?

Yes...my 6psi spring is a heavy bitch.


Look at the thing and think how the exhaust would flow through it.....Hint: exhaust should flow the same direction the WG opens.

Boost line off the turbo goes on the bottom port to OPEN the diaphragm.

There is no booost line off the turbo..

Force = area * pressure

area = pi * radius^2
