Hi, trying to hook up an SAAS mechanical boost gauge.

But can only get vacume readings.When on boost only goes to zero. Idling bout -20

On my second new gauge now and it do the same thing ! rrrrrrrr.

Have obviously searched this and found no answer.

Have tried both the following with no joy;

" And just T it in between the intake manifold and BOV is probably easiest.

Or T it between intake manifold and fuel reg. "

is on an 03 xr6T ute with rapid V1 cooler.

Does that vacume fitting on manifold have a return valve in it on early NZ BA's ??

Can I put a fitting somewhere else perhaps ?

thx all

What if;

I put a fitting in end of cross over on throttle side ??

Tee into actuator hose ?

Tee into sensor hose on I/c piping ?

thoughts people ?

just stuck compressor up butt of gauge and it workin good !

reckon I must have piece of crap in the line by tee at bov/ fuel reg ?

will rip it all off tamora and have another go .

is the car running ok ? , making boost , all the other things sound fine

seems all gud bud........just looking at my 2nd gauge ...haha .

Hole in brass tee to gauge looks way bigger ??

Something just being a tad difficult for us aye.

Always the easy part of a job that causes the probs aye.

thx

Na you right bud, reckon it way down on performance aye.

gauges and lines all gud.

mmmmmm ****

All fixed , close thread fellas.

How did you fix it? Let members know what the problem was so others can read your thread and fix it in the future

yes id like to know. hooked up a calibre boost gauge and reads about -20 on idle and only boosts to 0 and no more?

really frustrating me. the t piece is hooked in just before the blow off valve, on the BOV vac line...

cheers

All sorted had to actually drive it for it to register boost. Weird. Don't see why it wouldn't register when revving in neutral.
