Boost Gauge - Where Does The T Piece Go?

[sadr33]

No, don't T into that hose, as said you won't get vacuum.

On the back drivers side of the intake manifold there will be a vacuum line the same size as that one which goes to your standard boost gauge, T into that.

Basically you can hook your boost gauge up to anything that's plumbed in AFTER the throttle body, except the fuel reg hose, but that's at the front of the engine anyway.

Why cant you t into the fuel reg hose at the front. thats where mine is.

Why run a vacuum line all the way to the front of the engine when the line you require is available at the firewall?

looks ugly

It'll work but if you ever get a leak for whatever reason it'll affect fuel pressure and therefore fuel ratios. Best to leave something so crucial alone and use one of the many other points available, the standard boost gauge nipple is in the perfect spot and is the perfect size too, why wouldn't you use it?

Ah crap time to re route some hoses.

Do the S2 R33s Have a rubber cap on the front intake manifold nipple from factory?

ok, so im 99% sure this is right now lol.

I take the line i've outlined in red out of the sensor (circled in blue). Hook the T up to that, another tube back to the sensor and then the vac line from the gauge to the other end of the T.

Correct me if i'm wrong.

I dont blame this guy lol, i knew almost nothing about the engine lay out also, and the information given here was helpful but i was a bit reluctant to T into the BOV line.

My boost gauge is still sitting in my glove box, haven't had the balls to cut anything and connect it yet either.

But just to confirm, is whats said in this post and the photo above correct? if i follow this, would the boost gauge work with no troubles from the car 100%?

[Got a Pulsar]

Such a similar setup to mine that I'm gonna say yes.

That will work, no problems.

[suwidji]

waiting for my gauge to come in now..

Hethrow, if you've installed yours already following the photo i put up, could you let us know if it all works?

Cheers!

[hop1308]

yup, ill probably get to it soon. I just dont have anywhere to put the gauge yet, need to buy a pod or something to hold it in. wish i could just tape it to the dash loll

[Dose Pipe Sutututu]

^ buy a mount similar to this:

then mount on steering column or RHS of instrument cluster, or whereever it gives you an erection

[suwidji]

so, i bought a cheapo gauge from ebay last week.

http://www.ebay.com.au/itm/400336875504?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

how would i be able to tell if it's going to be more accurate than the stock gauge or not? Also has the same style mount you just linked Johnny

[GTSBoy]

The only way to know how good the cheapo is is to run it side by side with a trusted good gauge and compare. That's called......calibration.

[suwidji]

looks like i'm going to need to find someone with a good gauge then

[Brad54]

Speaking of good gauges and accuracy. Does anyone know what the quality of TurboTech's boost gauges are like?

I recently ordered a boost controller from TurboTech (after reading how awesome they were) and it came with a mechanical boost gauge.

Haven't hooked it up yet tho, wanted to know if it's even worth installing first.

Now I assume that they are not their own TurboTech branded boost gauges, that they merely on-sell another brands product packaged in with their own.

I also assume that with all the raving reviews of TurboTech's controllers they wouldn't go jeopardising their great reputation by supplying sub-par accessories; but hey, I might be wrong...

[suwidji]

I'm going to assume they're pretty accurate Brad. Like you said, they wouldn't jeopardise their product with something that won't show an accurate (or more accurate than stock) reading.

This might be a very stupid question, but I'm going to ask anyway lol.

I've read around that people test the accuracy of their gauge by using an air compressor.

I don't have an air compressor, but would I be able to use one of those free air hoses at petrol stations to test my gauge?

[GTSBoy]

You'd trust the pressure gauge on a free air hose at a service station?

/not sure if serious.

[Dose Pipe Sutututu]

you need a regulator on your air compressor and set it to what ever pressure you want.. then feed that to the gauge

[GTSBoy]

You still need a trustworthy gauge as reference. The gauges on air compressors usually read up to 1000kPa, so are not precise enough for ~100kPa readings anyway, and that is before you consider that they are usually cheap and nasty anyway.
