After market boost gauges

[amrbose14]

Are all aftermarket boost gauges likely to be of similar accuracy? Prices seem to differ wildly (~£20.... to much more).

Given that when you are on-boost you need your eyes on the road and not the gauge, does it really matter?!!!!

I've ended up moving mine to inside the glove box, not only because I never looked at it, but also because when on show it gave my car an unwanted Rice-Boy look.

Unfortunately, and obviously, i have no useful scientific knowledge to give a more sensible answer to your question!

I wasn't particularly keen on having one in the car (which runs a boost enhancer but is otherwise standard) ... only it would be useful to have a low pressure gauge kicking around - all the tyre ones go very high and I haven't much faith in their reading at low (like 1 bar) values. It looked like even the cheapest random gauge was ~£10 plus adapters), and a cheap boost gauge, which may be no different in function but is aesthetically designed to look OK (I sympathise with the glove box idea though) in a car, and has a flange already designed to take some hose, seems like 'worth the extra'... assuming I could believe what it said.

There are a lot of cheap and nasty chinese ones out there which are not very good, there are also chinese copies of the good ones.

Stick with a good known brand and from a good known source.

For some of my more expensive customers project cars in the workshop for tuning we have converted the standard dash gauge to show "above atmospheric" rather than "absolute" using an additional pressure sensor in the engine bay, which means they could see a guide of actual boost which uses a small box of tricks hidden into the wiring and can use a obsolete warning light in the dash as a "overboost" warning if the boost exceeds a set level. We have done this to 944's, but have also done it to 924 Turbo's and Carrera GT's to give them a Carrera GTS style boost guide in the rev counter... Neither option is cheap

That sounds right up my street but can imagine I wouldn't enjoy the price tag for it lol.

Jon - can you give an approximate all-in price (for the "above atmospheric" conversion and the over-boost warning light) for my car? This sounds more useful than my current hidden-in-the-glove-box modification!

Maybe I should have developed this into a proper product years ago when there would have been some demand for it, as I always wanted it to add some extra features to the same box of tricks.

If I am to do any more of them, I may as well put a little effort into making it a repeatable product, rather than something I have to custom make each time, which would make it affordable and plug'n'play into the harness without any splicing. Leave it with me for a few days.

American market series twos incorporated an economy warning lamp in their tacho (shaped like an up arrowhead), but Im not sure whether the Turbo model retained the feature. Offers a neat solution if they do.

This is something I would off thought we see more off and already done. Can't really get a nice place for ebc or standalone gauge with it still looking factory
