boost guages

[thehanko]

Has anyone had any experience with supercheaps caliber gauges?

I need to get a gauge in the near future and these are easy to come by, but i noticed a photo of one on ebay and it no longer sat with the needle at 0.

I once bought a vdo gauge second hand (im not looking to buy second hand this time) and it also didnt sit at zero.

is this a common issue with cheap guages?

Is there a way to check your boost levels with a temporary gauge? so as not to need an ugly set up permanently in the cab? I really only need to find out what the vehicle is running as it was modified prior to my ownership of the td42t.

I have a supercheap calibre gauge, the one with the blue backlit led in it,
This is my 5th one as i took the first 4 back, i know that some gauges rattle a bit, but these ones were actually loud and my stereo didnt help
apart from that they work ok. goes back to 0 etc etc

the rattle could be because the line to the guage needs a restrictor in it. I had a VDO boost guage that rattled until I fitted a restrictor with a 1mm diameter hole in it.

I ended up spending a bit more, I know in my industry the chain stores gear sucks and you want it to be reasonably accurate.

on the note of the in line restrictor the model I ended up buying had a 1mm restrictor in the back of the unit.

the boost line on the calibre units is so small you dont need a restrictor imo.

im running one and havnt had an issue with the boost gauge, its also quite accurate, inside half a psi, to what the dyno told me it was running.

the oil pressure gauge i have is also calibre and its a bit hit and miss, perfect most of the time, then other times turn the key and i have 20 psi without the motor running, and it will randomly spike on the highway from time to time.

hasnt played up in a few months lately though...

Gauges that don't sit on zero have usually been over-pressurised. Hard to do on a boost gauge usually.

not when people test them with an air compressor...which seems to be rather common.

and surely in the cheaper ones the face may have a tendency of moving this way and that a bit?

well with my autometre boost guage the bloody needle fell off. so you don't always get what you pay for they don't wanna no about it for a warrenty claim.
so i was thinking bout a caliber boost guage myself, are they any good?

their digital gauges (52mm) are 30% off till the 4th i think, $50 a gauge, running the tacho, oil pressure and water temp in the zook, so far so good
