hey, guys, i was just wondering where should i tap in my boost gauge vacuum line into. i was told to put it in a line where the intake manifold was, but i cant find any lines coming from the intake manifold. i would like to know where you guys hooked up your boost guage vacuum line to. please help???

 

There is a Gray vac line that runs out of the throttle body. Thats the line you want to tap into. The red circle is where my boost gauge is tapped at.

 

That's the best way to go if you really can't take your TB off. We have two test cars now where we removed the throttle body and tapped it directly. The car runs MUCH smoother and wont stall anymore, no matter how hard you try too. Even the TiAL bov worked great with the TB tap.

 

Wait, tapping in for a Boost Gauge will make your car idle funny? Or are you reffering to the turbo guys?

 

Couldn't agree more. My car runs way way better

 

Ive never stalled once with my car. It has ran perfect since the day everthing was installed. Both My brothers and my tC's have this same setup up and its just fine.

 

My car was the same way, but once i tapped the TB...wow...huge difference

 

Care to show us how or pics?

 

yea pics of throttle body tappage?

 

i second that.. and how much more difficult is that?

 

 

Any idea if the tap was done BEFORE or AFTER the throttle plate?

I guess the bigger hole tap would allow a better flow of boosted air / vacuum through vs the stock tiny pinhole which in turn produces better response for the EBC/MBC/WG/BOV.... Therefore less chances of stalling/idling issues when daily driven.

BSPturbotc, can you confirm on the positioning of your tap?

 

If you look at the first pic in the thread the throttle plate is at the same level in the TB as the bolts are. In the pics of the tap, the tap it self sits lower than the bolts so I would have to say after the throttle plate.

 

After

 

That looks nice I might have to hook mine up this way.

 

It would have to be after the TB otherwise you wouldn't ever reference vacuum at all, if any. The only vac you'd see is from the venturi effect. After the TB will show both boost and vacuum.

 

Joe is right. After the TB otherwise you will get VERY spuratic vac readings.

 

how does the first pic differ from where kaeon tapped his?




also will this small T that came with my boost gauge be any use? or do i have to pick up a bigger white one like kaeon used?

 

Use a 1/4" tee. It will fit nice and tight on the stock vaccum line. Then use a 1/4 to 1/8 adaptor. The adaptor will then accept the thin 1/8 plastic line that is routed to the vac/boost gauge. That would yield the same setup as Kaeon.

 

Is there a DIY for taking off the throttle boddy.......
