My Newsouth Boost gauge turned up today courtesy of Wazzzer, this might sound like a bit of a daft question but I'm going to ask it anyway :grin:
I've bypassed my n249 valve so I've got tubing going from the FPR straight to the top of the DV, shown in blue here (it is now red though!)
(http://i790.photobucket.com/albums/yy183/codling1234/IMAG0575.jpg)
I was going to T into the tubing close to the FPR, the tubing has an ID of 3mm. The problem being that the tubing on the back of the boost gauge has an OD of 3mm. I have a 3mm T-connector, but obviously that will not connect all the tubing together.
My question - do I need to get a reducing T-connector? If so where from? Or do I connect the 2 different sizes of tubing with a reducer and use my existing T-connector?
-
Is the tubing with the boost gauge like a hard plastic material?
Mine was with my new south gauge I just used a small length about 5cm of 4mm vac hose onto the t piece and then the smaller tube that came with gauge into the other end of the vac hose
-
If you have bypassed the N249 you should also have an unused nipple on the underside of the plenum chamber, I removed my N249 and N112 is it? and I had one left over.
If you need a pic let me know and I will get one later :wink:
-
All sorted guys, thanks for the help :cool:
-
Right then, next question! I got the gauge installed today and tested it when stationary (I moved it from the position in the video and am waiting for some super glue to dry :lipsrsealed:)

Is that a normal reading for the car being stationary? It was revved up to around 6k rpm. Obviously I'll test it properly tomorrow, but wanted to make sure that looked ok first :undecided:
-
should be below 0 if ticking over due to vaccuum
-
Have you watched the vid (click the picture)? It drops below 0, but when revved it only hits 5psi. I'm guessing it'll hit more when under load?
-
i didnt watch it not with it today mate thought it was a picture :laugh: :laugh: :laugh:
yes will be more underload mate :smiley:
-
seems about right to me.
-
is your car mapped yet?
-
loooking at it, it goes down? and it should be sitting at 0 when engine is running?
-
is your car mapped yet?
Yeah, been mapped for ages. I'll test it properly tomorrow, really wanting to know if that is about right for it being revved with no load.
loooking at it, it goes down? and it should be sitting at 0 when engine is running?
I thought it was supposed to sit at 0 with the engine off, and drop below 0 when idling?
-
something wrong mate mine idles at 26HG(Vac)
-
my needle sits abit lower than that on tickover will hit more psi on load
-
something wrong mate mine idles at 26HG(Vac)
yeah mines around the same
-
Just to check, I've bypassed the n249 valve so the pipe coming from the fpr goes to the bottom of the inlet and another pipe goes from the bottom of the inlet to the top of the d/v.
I've T'd into the pipe going from fpr - inlet, that the right one?
-

yea thats right
any kinks in the boost gauge hose?

Nope, don't think so, all pretty much straight.

this is mine (cold)

^^^^ thats how it should be
-
thats how mine is on idle sits on -20 under load gives your boost whatever it is and engine off sits at 0 so summat wrong there dom
-
It doesnt matter where you T it off. Mines T'd off my DV as I dont want any connectors in the line to the FPR.
Mine idles at about -25 in vacuum. 0 when the engines off.
-
Dom check the line from the back of the gauge, give it a suck and block it off with your tongue and see if it drops on the gauge. If it does you know it's leaking on that olive union.
I used to sit on -18 in hg on idle
I'll look at the video when I get on my PC and not on my phone

Will do, it's all hidden behind the dash now though :grin:
I'll wrap some cable ties around the t connector as well, I didn't have any earlier so left it without. There's a possibility that it's leaking there as well.

Mine was the same, so something wrong somewhere
-
:laugh: mines a differnt gauge!
mine starts from 0 which would be why i was confused :rolleyes:

Right, so the problem lies with the boost gauge tubing some where then? I guess I'll have to check it over tomorrow!
-
lol you've got a dirty diesel gauge :grin:
Dom if you want I'll send you some sealant that I use on joints like the olive one on the gauge, it's from work and we use it for vacuum bagging
Should have sent you a load when I sold you the gauge but I forgot :embarassed:

I'll have a check over everything tomorrow and see if I can sort it, if not then that'd be great. I haven't done anything with the pipe coming out of the gauge, I assumed that the seal would still be ok. I think the problem is with my T connector personally, it seemed a little loose :undecided:
-
ah I think we may have hit something here, that pipe on the back of the gauge was only finger tight...
-
Righto, that'll be the first check then :grin:
How does it attach onto the gauge? I didn't even look!
-
Might be best to remove the fitting and refit it with ptfe tape around the threads.
-
Just got to work, there was a hissing noise coming from the boost gauge so I'm assuming that is def the problem. How is the tubing attached to the gauge? Does it have a threaded connector?
-
the tubing attaches to the nipple at the back of the gauge
-
Some PTFE tape and a tighten and it's sorted:
