Ideal Vacum Lines

Santo Domingo 2.5 RS · 07-03-2003, 07:17 PM

HI, i am ready to begin installing everything, i am not really sure yet, of where should I tap for my vacum lines for everything I need to install. And is there any benefit for hooking them up on a certain way?

These are the thing i need to get boost readings for:

J&S Safeguard
Boost Gauge
Turbo Timer
FMU
Boost Controller(EBC)
BOV

There are two vacuum fittings on the passenger rear of the intake mainfold that you can use for vacuum source.

Yes, Ive seen them, but they are both on cyllinder 3, I dont like the idea of hooking everything to an intake runner. Maybe having so many Tees there might not give me the best readings.

Are there any other places where I can tap to get boost readings?

The only other place I can think of is where the map sensor sits. But then you'll have to take it off put a pipe in there and tee the map into a vacuum line.

The most preferable location is in the center plenum of the manifold, obviously. I don't think I have anything on my #3 runner because of all the errors in the readings... my Haltech used to vary between 3.2-5.1psi when I was only boosting 4.5 solid because of the valves opening and closing. FPR's also vary pretty quickly on there as well.

I actually have an external MAP sensor and intake air temp. sensor, so I made a plate to replace my MAP sensor that has several other vacuum line inputs, and I have a double T on the other port near the TB.

so if I dont make a plate for the map sensor. The only place is the intake runner? Arent there any other places where i can just cut the lines and tee on them?

There are no other places. Unless you drill the mainfold.

Can you all please post where have you tapped the lines for each different thing (Fmu, Bov,etc..)????

I think You might need better readings for some things, and for some other you might not. What have you guys done?

8 - what were all those 1 way check valves for? (atleast they looked like little check valves - filters?)

8Complex · 07-05-2003, 12:57 PM

Joncas - Where are you looking? I don't think I have a single check valve in my system in my car...
