1985 Grand National with an adjustable waste gate has 2 hose connections, one is off the turbo pressure port, the other connects to the waste gate control. I would like to install a manual boost controller, what would be the proper line diagram? Roger
Waste gate has an adjustment eye on it, not sure if this would be called adjustable? I have the preload set at 3 full turns.
If your controller is the bleeder type, then it would replace the stock solenoid, so you can bleed off manually. It sounds like you also have an adjustable wastegate, so you could change the preload to alter boost also.
