I realize people run a line from the nipple to the wastegate... but I'm going to be running my wastegate off my vac manifold.

So what do this nipple do?

Do I cap it or what?

 

it goes to wastegate

but since u want to get the boost signal from the manifold, yes CAP IT

 

Is there any advantage of getting the WG vacum from the IM rather than the compressor? Mine is connected to the compressor.

yes.. when u run it from the gate to the Intake Manfold, the gate will open up at exactly what the manifold sees...if u hooked the same up to the compressor, you will not be boosting exactly the same PSI, it will be a little less, due to the intercooler's pressure drop.

 

So youre saying is better/more accurate to run it from the intake manifold?

If so then i can put a "T" on one of the vacum lines on the Manifold and run the WG line from there?

 

yep, just make sure that it is strong enough that it will open up correctly. IE: no like the FPR vacuum line, something bigger.

 

When i had my sc34 i went off my fpr vaccum. that will work good.

^^yup i had to learn the hard way. now i just cap the sucker and run it from a tapped line off the IM. before i was always wondering why i had inconsistent boost.

 

what kinda of cap? something that will hold high pressure I assume....

maybe a thick cap and a clamp will do...?

 

On the contrary, i find that using the pressure signal from the turbo itself gave me the best response. Its also easier to spot if you have a leak in one of your charge pipes. But to each his own.

I had a hex-type screw in plug that came with Flamenco-T's oil line kit (i think?) if not it came from one of my autometer gauges. So i just removed the T and stuck that in there

You have 2 options:

Connect the vacuum line to the port on the compressor housing.
Pro- This will allow the wastegate to more consistently control the response and ability to control boost pressure. In turn this will help deter boost spikes or quick heat soak problems with your intercooler.
Con- Since there is a 1-3 PSI pressure drop through the intercooler piping and intercooler the wastegate will start to crack earlier and your torque curve will suffer because you will never reach basic boost setting on the wastegate.

Connect the vacuum line to the intake manifold or a line connected to the intake manifold.
Pro- This will allow slightly better turbo response because it will allow the turbo to boost all it wants until the pressure reaches the intake manifold.
Con – It will allow for more brief spikes in boost which will cause the intercooler to be hit with a blast of higher temperature.
