Holset hx35 question

[RocCitySlayer]

Can somebody tell me what the nipple with the black cap on it is?

 

[Kalub]

A pressure source to actuate a wastegate

 

[RocCitySlayer]

It has been capped since i bought the car. Any reason it would be capped and not connected to anything?

 

[Kalub]

They decided to use another source to actuate their wastegate? Maybe they had one on the lower intercooler piping that was closer. Who knows.

 

[dsmvenge]

does it have an external wastegate or could of been the boost gauge source or the mbc it may of been taken off and capped

 

[RocCitySlayer]

The Bep housing is internally gated. Can the be used for a manual psi boost gauge or does that go somewhere else?

I have an electronic bar boost gauge and I have been thinking about using a psi gauge

 

[Kalub]

Most people run a boost gauge off of the fuel pressure solenoid. It's closer and it sees vacuum and positive pressure.
