Mechanical Wastegate Spring Rate...
I wanted to share with everybody who is looking to build a mechanical wastegate controller (aka homemade TurboMaster) that a spring with a spring rate of 50lbs/in seems to work well. I just got my gauges hooked up this weekend and noticed that my homemade controller does not seem to "peak" then drop to a sustained boost as my previous Heath unit did. Rather the boost comes up and holds steady at 11PSI, without dropping back.
I got the spring from McMaster Carr. If I can find the part number, I will post it in Part Point...
Hopefully this helps!
