60549, how can I lower Boost w/Hahn 8psi wastegate
Posted by CrashedMax, Nov-11-03 04:36 PM
I saw a post that mentioned lowering the boost on their 10psi wastegate. Can I do this with the Hahn one, if so how? I'm just installing my 30# injectors, Walboro 255, and SFMU soon, and don't want to be boosting big till I have loot for the rebuild next summer. I want to play it safe for now.

If you want to turn it down take the pin off the wategate actuator arm and screw the end out, then lock it with the lock nut and put it back on with the pin. This will make it take less pressure to your wastegate actuator to open the wastegate giving you less boost. I don't know how much play you will have in that arm, its for fine tuneing. I think you could get it down to 7-8 psi no problem.

You could also find someone that started with a Stage1 and trade wastegate actuators with them... the HRC Stage1 wastegate actuator was set at 5-6psi.
