k31th less WHY; more WOT Site Developer 29,161 Member For: 16y 9m 15d Gender: Male Location: Melbourne Posted 05/08/16 02:01 PM Share Posted 05/08/16 02:01 PM Since there's no source to "hold it closed" then you only need to connect one end onto the gate (probably the top connection, but check your diagram - one will "help holding it closed" and another is the "crack open pressure/vacuum source") and it'll act like a IWG just with more volume control (hopefully it's bigger than a ported wastegate).

eff xr6t Member 569 Member For: 11y 3m 26d Posted 05/08/16 02:46 PM Share Posted 05/08/16 02:46 PM Like so.Or you can run it from the turbo nipple straight to the solenoid then from the solenoid to the bottom port (closest to the flange) and leave the top port vented to atmosphere. 1 Link to comment Share on other sites More sharing options...
yellowgsr Member 65 Member For: 16y 17d Posted 06/08/16 12:32 AM Author Share Posted 06/08/16 12:32 AM So the existing internal wastegate line goes into the bottom port of ext wastegate? Link to comment Share on other sites More sharing options...

If your base spring pressure is correct that'll work just fine. Eff's second method is best for finite boost control but does need more tuning to get right.

yellowgsr Member 65 Member For: 16y 17d Posted 06/08/16 02:12 AM Author Share Posted 06/08/16 02:12 AM ok. what about the the top port of the ext wastegate? where do I plug that in? Link to comment Share on other sites More sharing options...

Plugging it will make it over boost as it will prevent the gate from opening. Best practice would be a fitting and shirt length of hose run off the top port to atmosphere, but pointing Down to prevent dirt/water ingress but in reality it's not really required.
