[QUOTE=Bidja;791595]Maybe metal pipe acting as heat sink and heat transferred into rubber hose @ connection.
Interested in learning here _ the boost controller (vented) in your set up @Hodge , does it provide a boost bleed to atmosphere so that actuator sees a lesser pressure and wastegate remains closed longer so the turbine spools up low down to for improved boost early?[/QUOTE @Bidja
I think it's a simple boost limiter. Spring inside compresses at set point and lets excess boost out , so as to not push the actuator any further.
The earlier linked versions , are a inline setup I believe . No tee piece. Hose put of pressure side of turbo, through the controller and out onto the actuator.
As for the hose. I really don't know. More so how the hose and the controller gave up in one go.
Prick of a place too. Had to remove the intercooler to get to it. Now to find some quality hose.
