what decent boost gauges are on the market atm?
need one reading upto 2.5bar and 45 mm
i ve a racetech one atm and its never worked right from the second i bought it,
i ve looked at stack gauges but they only read upto 2 bar and are 52 mm

 

45mm is a really unusual size?

 

is it??
as far as i remember thats what all my gauges are atm
will check in the morning to make sure

 

The most common size is 52mm... Never seen a 45mm before.

 

mine is a vdo 3 bar one nice a plain looking black face but 52mm

 

mmm starting to think mine are 52 mm now
the vdo gauge looks fine, as you say james plane and simple

 

Its accurate aswell the cars set at 2.6 bar and the gauge sits dead on 2.6bar

 

You can buy 45mm gauges.

And Ive used the Racetech a few times, never had an issue. It's a very basic mechanical gauge, isnt exactly much to go wrong ?

What exactly is wrong with it ?

 

my car is running 2bar of boost, but my gauge is only reading 1.4-1.5ish,
and thats what it was reading the first time i fitted it after getting mapped,
it reads 2 bar on the laptop, ai mapped it

 

have you looked if autometer do any that high

 

Cant say Ive ever seen a mechanical gauge that far off, even a shite TIM turbo one. But Ive used the racetech on cars up to around 2.5 bar and they've worked fine

The only time they go off, is if you seriously overpressure them and fuck up the internals. But then that's obvious as the gauge doesnt reset to zero when the car is off. Where is the signal line taken from ?

Do 0 and vac readings appear normal ?

 

signal is coming off vacum outlet on the inlet,
and no vac reading is nt normal, cant remember what its reading but i remember jonny saying its way out
maybe i should try taken the signal from somewhere else?

 

Signal location sounds fine.

 

just checked my gauges there,
all 52mm and not 45mm what i thought they were

 

Mine is a 2.5bar Racetech one and it reads fine.

Stack gauges. simple, reliable, accurate, and look nice.
(and not as much money as you think, Ł50 I think for a 'mechanical' boost gauge )

 

Ditto
I bought one last month for about Ł50 though mine reads PSI rather than BAR but there the same price either way

 

Is it best to stop mechanical or is digital ok? Also what is a stepper motor gauge?

 

Pay the few extra quid and get the Stack electronic version. It also reads upto 2.5 bar and doesn't show annoying vacuum.

Like this:

I have an electrical stack boost gauge for sale for 50 quid if you're interested. Bought it off someone on here but never used it as bought a ford racing one instead. Pm me if interested

 

on the electronic gauges where do you take the signal from??

 

I also have a stack electronic gauge... And it's very very good.

 

Pressure source is same regardless. Electronic gauges have their own map sensor though

 

ive got a stack stepper motor boost gauge for sale lol. comes with its own map sensor like steve says.

Ł90 delivered

reads 30psi tho



i also have a stack stepper motor fuel level gauge (far right) for sale Ł75 delivered



all others are now sold

 

Most swing style gauges ( not mechanical ) are basically volt meters.

A voltage makes them read higher, but gravity or a spring makes them return to default.

A stepper motor controls all of the needles movements using motors. Whether that be up, down, whatever.
So I guess they have the potential to be more accurate. Or more prone to problems.

As for the Stack stepper motors. Ive only ever seen two stack rev counters which were stepper motors. If all of their gauges work like that, I'll never own one.
Very jerky, slow and not nice at all. Given the price of them, quite terrible really.

When I seen the first I just assumed it was faulty....but then I seen a Stack dash which was exactly the same.

 

yesterday i got the lend of my mates big professional gauge,
car is boosting to just over 2.1bar, so that goes to show how far out my racetech gauge is

 

Can't believe nobody has mentioned the awesome TIM gauges?

 

It must have been damaged somehow, or the internals are leaking air.

It's very rare for any mechanical gauge to be that far out, even very cheap ones. Ive never actually seen one of any brand that bad that hasnt been damaged.

Even a cheap sub Ł5 gauge from a pneumatics place.

Either way, time for a replacement

 

Ahh, but they have...albeit briefly



And truth be told...my first ever boost gauge was indeed a TIM !! some 19 years ago ! It only went to 1 bar though, so soon needed replacing

 

My first one was a TIM also, again about 16 years ago. It's now attatched to my PC at work to meadure the boost AutoCAD generates.

 

Liking the look of the stack, but was hoping for one to go upto 2.5 ish bar and still do upto atmospheric!

 

bigger turbo and less boost lol?

 

just go vdo it reads up to 3 bar so always room for more boost if you go more power lol plus its cheap
