Boost Guage line

[nickpeacock36]

Is the attachment showing the correct place to fit the hose leading to the boost guage? I want to weld it on tomorrow so ijust want to make sure.
Thanks

You can mount it there and I have seen it done before, mine is mounted after the intercooler and works spot on

I thought that was after the intercooler. Now i'm more confused, Doesnt the gas run through the cooler and down into the turbo?

[big_fletch]

No the turbo sucks air in from the airbox and forces it into the motor after running through the intercooler.. the intercooler is designed to cool the air down before entering the engine

That makes sense. Thanks for putting me straight, i have a lot to learn. So the other pipe coming from the intercooler is best then?

Probably won't make much of a difference, however I put mine there as its the closest spot into the intake of the motor so would give the most accurate reading of boost pressure entering the motor

Ok, just removed the other pipe. and marked it for welding. Now i think back, thats also where Tony told me to put it. The picture i found got me mixed up. Thanks for your help Fletch.

Where does the other pipe go Tony?

Which other pipe?

One side of the brass T-piece goes to the boost gauge, the other to the dawes valve. Is that what you meant?

Tony

[nickpeacock36]

The thread on the fitting i was supplied looks fine to be a standard metric, do you know if its a special thread?

Tony
Yes that is what i meant. i just posted about thread. can i change to a t later easy?

[nickpeacock36]

Can you use the guages before connecting up the electric? i assume power is just for the lights.

The thread I welded/brazed in was a standard (1/4 npt I think) thread, it's the same thread on both ends of the T-piece, so yes, if you do that it's a simple case of unscrewing the boost gauge line, fitting the T-piece and screwing the boost gauge line into one end of the T-piece.

Correct, VDO boost gauge is mechanical, the wires are just for the back lighting.

Thanks Tony, is that the same with the pyro?

[YNOT]

Thanks Tony, is that the same with the pyro?

No, the pyro has a thermocouple sensor so will not work without power.

Got the boost guage working sort of. I stuffed the olive up that goes into the cooler but managed to fit one from a bike brake system temporarily. The guage makes an annoying rattle noise when it's returning to the 0 psi point. Is this normal?

Did you fit the tiny restrictor that should have come with the boost gauge?
My boost gauge has a very light rattle if you listen carefully but once you start driving and have the radio on you can't hear it at all.

Yes i fitted the white plastic restrictor in the guage. i guess you wouldnt hear it if radio is on but you dont have to listen carefully, but why does it do it? i need to replace the olive engine side. do you know who sells them?

[YNOT]

Your gauge may quiten down, I don't notice mine any more.

Try VDO for a new olive, or anywhere that sells VDO parts.
