Boost gauge vac pipe where TO?
 

Hi there

I know us are all gona go mad and say go read different threads but i tried and there is alot of different opinions :wonder: couple of them ive tried and no joy so need little help its a version 4 sti , boost gauge might be crap now but it was there when i bought the car just wasnt installed fully since i have the car on the road now i need to have it, so where do i connect that vac pipe for proper results? :brickwall

Can you see a rubber blank on a pipe to the left behind the alternator.

id have to have a look 2moro, car is at the job if i have would that be the place ?

would it be the pipe facing up from the inlet manifold?

Yes take the rubber off and connect to it.

something in there already :D just put a T piece there ?

Om my V4 there was a rubber blanking piece on the end of a spigot on the front right of the manifold top, seen as you looked under the bonnet from the car' front. Remove that, slot vac pipe over the spigot.

Ill try to look for it today ill type in later whats what later,
Can u see it here Alcazar? i see 2 on the right of the coil pack on top of the inlet manifold which is 1 for the hks bov and the other one im not sure.https://cimg5.ibsrv.net/gimg/www.sco...4c23674041.jpg

Attachment 21623

So tried left side taping in to pipe and right side of manifold to bov no joy on any of em :/

Maybe gauge is duff.

It does go up and down as its self testing when ignition is on lights up and all that, anyway of testing? Would it work if i blow air in it w/ compressor?

Which gauge do you have?

Is that the boost gauge sensor mounted on the bulkhead on the drivers side and the pipework wrapped around the strut brace ?

Mick

Timex boost gauge, yes thats the gauge sensor and hose wraped around strut brace

So am i right thinking that it is not a mechanical type boost gauge but an electrical one with a sensor.

Ermmm its vac pipe to sensor then sensor wired up to gauge but the actual gauge is something likhttps://cimg4.ibsrv.net/gimg/www.sco...29bea10682.jpg

e this slightly older type maybe but everything same otherwise the gauge is actually stays on 50 for some reason connected or not connected and tried driving it connected to left side or right side of manifold and no movement in the gauge at all

Probably gauge is duff and maybe the sensor as well so if i were you i would buy a mechanical gauge that does not need a sensor .

Right, new gauge it is so, thanks for help guys

Keep in touch as to the outcome.

The question is now what to get i see popular ones are slightly expensive i found prosport which is reasonable but that is with sender..

The prosport boost senders can be bought separately when they fail. About £20 for the last one I got

Id like to get one without sender as per johned

I run a Tim boost gauge,cheap but reliable :thumb:

With sender or mechanical? Accurate?

Mechanical and very accurate.
I do my own mapping and the gauge is bang on to what the ECU reads.

Any chance of a link which exact one? Id give it a go

Also available with white face.

Yeah, I bought the white face version of this 2bar TIM gauge. Just gotta get round to fitting it in place of my existing one.

TIP: before installing, replace the std filament bulb for a multi-SMD job. The difference in illumination is night and day... In both brightness AND uniformity.

Nice tip @joz
I shall be upgrading my bulb me thinks :thumb:

Link to said bulb please? :)
