As the topic says. Where does this go?

turbo-crx

its the reference line fitting for the wastegate.

does it need to be hooked up?

im currently not running a boost controller and i have a tial 44mm wastegate. so i believe i cap the top of the wastegate off and run the side port to a vacum line on the throttle body. if that is correct i have this "reference" line thats just sitting open.

ive looked at that. and nowhere on that chart is this reference line.

so, anyone know what this actually plugs up to if anything?

TimKennard

that fitting on your turbo goes to the bottom port of your wastegate. since you are not running a boost controller, then you leave the top port of your wastegate open, do not cap it!!! otherwise the diaphragm in the wastegate will not be able to be pushed up to bleed off pressure from the exhaust.

thanks timmydogg. just what i needed to know.

so will i not ever hook my turbo up like that diagram since my turbo has that reference line?

It's essentially the same as how it's specified in the diagram. The key being "before the throttle plate".

TimKennard

the diagram is the same really. the wastegate needs a boost source that is before the throttle plate like stated above. its better to have the wastegate get its reference as close to the source as possible. boost will be more stable. thats my opinion and i'm sure others. think about what is happening in the system. exhaust gas spins the turbo which creates boost. the wastegate bleeds off exhaust pressure based on the reference boost, thus controlling the boost. the spring determines how much reference boost is required to open the gate.
