Should I try and block it off or use it as a vacuum source for wg. Any opinion is appreciated.

 

its a matter of personal opinion. most block it off to get the boost reading for the wastegate AFTER the intercooler.

 

I'm not sure what would be better. It's either the nipple for a vacuum source or my vac mani which is tapped off brake booster.

Use your vacuum manifold off the brake booster. just plug the nipple on your compressor

i don't think that nipple sees vacuum. it would be called a boost source.

I've been told it does see vac but I could be getting the wrong info.

 

not trying to steal ur thread but does anyone know what size plug to get to plug up the vacuum source on the compressor for a turbonetics t3/t4 ar63 .57 trim

C'mon now why does everyone insist on trying to buy something to fix their problems? Get crafty!! Pinch off a piece of rubber tubing or something and slap it on there.

And unless the nipple is on the intake part of the compressor housing, it's going to be a BOOST source not a vacuum.

1/8 Npt I THINK

DJFOB&gt;&gt;&gt;&gt; DO NOT Connect it after the TB it must be BEFORE the TB so you vac mani WONT WORK! Just use the hole for the wastgate like you are suposted too. If any thing put it right past the intercooler but NOT BEHIND THE TB!

Thank You And Have A Wonderful Day

WTF mate?! I'd say at least 50% of the FI users on this baord are running a vacuum manifold from the brake booster line, which is after the throttle body. Are we all wrong? No.

Are you trying to say that there's no vacuum after the throttle body?

hmmmm....thats funny. Mine works just fine with the boost source off of the intake manifold.

That's what I did. Well...I just took some vaccum hose and plugged it with a bolt ;P

 

Vacuum manifold is fine to be post throttle plate, but the boost source for the wastegate should be pre throttle plate, especially when using an MBC.

 

Correct the port is 1/8" NPT.

What the hell are you talking about?

Where is your boost gauge tapped into? The intake manifold, right?

What boost level are you trying to regulate with a boost controller? The boost in the intake manifold, right?

So why would you source a boost controller from anywhere but the intake manifold? Sourcing the boost controller at the compressor housing is going to make it regulate compressor housing boost, not intake manifold boost.

 

I think either way would "work", the only difference is that the boost pressure in the intake manifold will be less than that of the turbo nipple. If you are using a boost gauge, you can see the actual difference and adjust your MBC accordingly, or if you are only using you wastegate to regulate boost, then tap off of the manifold.

Because sourcing the BC off the IM can cause a vacuum leak. The BC isn't supposed to se vacuum, hense the reason it should be pre-throttle plate.
