Boost Gauge (were to you tap in)

[dman555]

I just bought a new gauge and need to know whhat vacuum line do you tee it off of ??????
Any help please!!!!!!

 

[Alejo_NIN]

people advise to tap it from the vaccum line to the brake booster
others argue that it makes no difference and to tap it from the nipple on top of the mani where the BPV and WGA get their vaccum and boost from

the latter one is where i tapped it, no problems

Is that the metal nipple of the back of the intake that has the tee in it already that splits on into two ????.
I taped into the hose off the wastegate to intake man, The small blue one.

in my car is was balck

the nipple is right on top of the mani, in the middle

Blue? Just follow the line that is t'ed off to to BPV and WGA back to the IM. That will work fine. Tap the line close to the IM.

Just got my car last week. Not so smart with the abrevations.
Thanks guys!!

bump for pics......im doin the same mod, need help

My bad, BPV = By Pass Valve & WGA = Wastegate Actuator.

Using the brake booster may be better (I really don't know), but this has worked fine for me.

Look at the white t-fitting. That is where I have it tapped.

Wow,
thanks for the pic's and that helps so much better when you can see it.
I have a bit more boost useing the spring trick on the WGA. But my boost gauge only hits 5-6 psi.
Should it go higher with this mod ??
The car pulls alot better with this done to it. I also put in some denso ik22
cold plugs.

is this a problem to hook up, if you do the 626 mani swap. is it still a functional source? i havent done the swap yet, gonna hook the gauge first then mani. Any comments?

dman, you say you have the spring mod to increase boost a little, huh? 5-6 psi is stock boost, so either the spring is not doing anything or you may have some sort of leak. With the spring mod you should be seeing a little more boost, unless the spring has slipped off or is just worn out.

What is your vac reading at idle? It should be be right around 20 InHg. Also, make sure that the guage sits at zero with the car off. Check all of the vac connections to the guage for leaks, both in the engine bay and at the guage. You should use teflon tape on any threaded brass fitting such as the ones on the back of the guage to prevent any leakage there.

You really did not need colder plugs if you are only boosting 5-6 psi. However, they will not hurt anything. They may not last quite as long as stock plugs though and the IK22s are pretty expensive.

Looking at the picture of the 626 mani sold by ProtegeGarage, it looks it has the same vac nipple on top. So, I don't think it would be a problem. Even if it is different, it would not be hard to find another vac source with all the lines we have under our hood.

this is were I have my boost gauge installed between the vac line and bpv.

You probably want to put it closer to the manifold for a more accurate reading.
