I'm about to install a boost gauge and I have read all the guides and looks easy enough............but.........pardon my ignorance :embarrassed: , why does it T into the fuel pressure regulator? What does that have to do with boost pressure? Wouldn't it make more sense to go on the vac pipe on the DV??
I ain't no mechanic so I'm probably well wrong but wouldn't that mean you could stick a boost gauge on any old car not just a turbo? :huh:

:huh: just put it into the pipe going into the top of DV matey

That was my first plan but then after reading tons of guides they all say tap into the fuel pressure regulator so now I'm confused?!?!

That is correct, just tee off that pipe as required.
-
Both of them are vacuum pipes and both go to the inlet manifold so they both have the same pressure in them!! Just if you use the fpr vacuum and you have a leak on it you can end up running lean :lipsrsealed:
Also off the dv you need shorter pipe!!!

So would you recommend running off the DV then?
-
Personal preference really, I had it there cos it ran under the bulkhead hidden
-
Sweet! Think I will just tap off the DV then and maybe move it at a later date. Cheers!
-
If you have a leak anywhere you plumb the boost gauge into you will run like a bag of poo, not just at the FPR

Cheers for advice! One more thing, i have a smoked face boost gauge so it only shows with the backlight on. Can i still tap into the dimmer light or will it only work when the lights are on?

yes mate you can tap into that ...thats what i have done and yes again will only worjk when lights are on :wink:
-
Hmm.. Need a line which comes on with the ignition?! Any ideas other than the radio? Wires a bit short so need something near the a pillar?
-
Or extend the wires :lipsrsealed:
Only thing not doing it on dimmer is if its too bright it might annoy you at night
-
If you go behind your fuse panel, there should be a few thick yellow/black wires, they're ignition switched. Ive got my sat nav tucked behind the dash and tapped into them so there's no wires hanging about.
-
one of the wires to the headlight switch is ignition live, can't remember the colour though
-
Well I've been trying to do this for the last half hour and have failed massively :embarrassed: !!! For the life of me i can't find how to get the boost pipe into the cabin without drilling a hole through?! I know all the guides say put it through this or that gromit but i can see f**k all that looks gromitish?!? Tried following a few electric cables but no luck just seems to get stuck somewhere! :angry:
Fuming, i hate it when i cant do something :angry: reckon a trip to the garage is my only way :embarrassed:
-
Where abouts are you??
I ended up runnin it down where the bonnet pull is

I've given up for today! In in beckenham area (if that's what you meant?)
I looked at the bonnet pull line but again once it goes out of site just gets stuck?!
Done bit of research this grommet that loads put it through is only free if the car is not cable throttle which mine is so theres no free grommet to go through.
The drill keeps coming to mind :grin:

I have a 3 wire boost gauge but found I only needed to use 2 wires,
One was the earth and the other onto the light switch,
It dims as it should and works as it should, I cut the other wire off
-
the other wire you cut off dims the LED when you turn the lights on

The LCR must be different, The lights on the dash come on with the ignition as does the boost gauge. When I turn the lights on they dim aswell, but so does the boost gauge.
