What is the recommended maximum pressure for a N75 valve ?
Is it worth the money to swap to Mac valves. In that case 3 or 4 ports.
I have a Forge internal wastegate with 2 ports.
Advice appreciated. Jérémy

Re: Closed loop boost
There is no maximum pressure, it all depends on the air flow, back pressure, and many other factors.
If you don't have boost creep, you're fine.
If you do have boost creep, this could be a factor.

Re: Closed loop boost
Can someone confirm the pipework connections for the MAC valve fitted to an internal wastegate actuator, is this correct?
Port 1 To atmosphere / filter
Port 2 To wastegate actuator
Port 3 Boost pressure from intake
"Edited now shows correct fitting"

Re: Closed loop boost
Your MAC valve looks to be a fake to me. Plumbing looks also incorrect as you don’t feed air through the Common port
