Post by: golf1.8t on 18 March 2005, 11:17
just got my boost gauge and not sure how to fit it any help would be great and save me some money getting it fitted for my next mod thanks

Use the one that goes to the top of the dump valve.

how did you get that nylon tube through to the inside of the car from the engine and what valve have you got there recirc/atmos

i tryed that pipe but it seems to be a bit jumpy wen i rev the engine

don't use that hose.  Use the one off of your fuel pressure regulator.  It is a direct feed off of the manifold.  The hose going to the diverter valve has pressure regulated by a couple valves and is not accurate

I used zip ties to run it next to the hard plastic brake vac line.  Then I ran it in the firewall thru the grommet located next to the brake booster

It does'nt matter where you put the vaccum pipe as neither place is accurate as the boost is controlled electronically.  To get an accurate reading you will need a digital boost gauge which wires in to the ecu.
To get the pipe through to the engine compartment, remove the scuttle panel, remove the wiper mechanism and there is a small plastic cover undo this and it you can put the hose through here, just feed it through and if you take the fuse box cover off  you will see the hose poking through.  voila.  I did have a guide with pics on how to do it, but i cant find it sorry

is an electronic gauge the same thing as a digital

we aren't talking about controlling the boost, just reading it.  The line for the FPR is right off of the manifold which is the pressure you want to be reading.  As long as you have an accurate guage it will give you the info you need.

thats what i meant, a vaccum gauge wont give the correct boost pressure reading, an electronic 1 will.
That said, I have a vaccum gauge in mine, as they are cheaper and they are only out by a tiny amount.
They look cool as f!@k anyway, so whats a few psi between friends :laugh: :grin:

this one would be accurate

a few psi is a big problem for us big turbo guys

what is that an electronic gauge?

what is that an electronic gauge?

digital display and it wires in to the ecu so it gets a true reading.
