dumb external wastegate question
hey guys, so i removed my external wastegate to change the spring, and didnt make a point of noting which side the vaccum line was attatched and which was the vent side.. do i hook it back up to the side that sucks the gate open, or the side that sucks the gate closed??? without the spring in it i can operate it just by sucking on it with my mouth lol.. i know if i hook it up backwards its no good.. thanks for the help!!

They are all different Im aware, but function the same way more or less... Vac line on the nipple that sucks it open or closed,? I have 2 choices lol...

you're thinking backwards still. pressure line on the one that OPENS it when PRESSURE is applied.
and no, not all are equal, synapse for example has 3 ports that all function differently. what you DO NOT want to do is have someone hand you the wrong answer, because it is not that simple. an improperly routed wastegate could cost you an engine.

How soft of a spring do you have in there that you're able to suck it open with your mouth? lol the way a wastegate works is that a certain spring puts that much pressure in keeping the diaphragm closed. Once you reach a certain psi of boost, it overpowers the spring and the diaphragm opens.
Regardless, find out whatever brand it is and look that **** up. No one, unless they're running the same gate, can give you a definitive answer.
For what it's worth however, my precision 46mm gate utilizes the side port for the boost/pressure source. The top one is used in electronic boost controller applications.
