Disconnecting Wastegate OK?

So I have a problem with low boost on my 38r turbo, before I start adjusting the wastegate rod can I take the c-clip off and pull the rod end off the pin and take it for a quick rip to see how much boost it will make with the wastegate staying closed? Or is that a big no-no?

Thanks, Jon

I don't belive it is the same thing, the wastegate is spring loaded and still opens if the pressure is reached without the red line to open it earlier

It won't see any boost if that line isn't hooked up... unless you have a turbomaster wastegate controller... or something similar..

you're saying if you disconnect the rod from the exh housing the wastegate will be left open? Makes sense as the spring holding it closed is in the diaphram

Disconnected red line on mine for like 7 years. 28-30 psi with stock injectors....40-42 psi with hybrids. No issues for me.

Re: Disconnecting Wastegate OK?

You'll be fine. Was pushing 14 psi with mine before unplugged the red line and now at 26-28 psi.
