Hi Chaps,

Now TBH i dont know how these boost guages work with a stock Comptech SC+aftercooler and Fpr.

Does a pipe just run to the fPR?

Does it need power or just one pipe running to the guage?

I apologise for a rather newb question but i have no idea, honest!

Anyone got any pics?

Cheers

 

what kind of gauge is it? My Prosport boost gauge feeds off the intake manifold

 

I have not bought one yet mate.

Ah i see, thanks for the pic so you run a T peice to just feed to a gauge thats all?

I take it there are electronic and mechanical types?

 

for a boost gauge you just T whatever vacuum line you want. i chose to not use the fpr vacuum line. i think i used the air pump one for the bov and boost gauge...

 

Hi Eddie

I have seen these on ebay, looks like they would do the job?

TBH i'd prefer an electronic readout of the boost, i take it its the same as connecting a mechanical one i just need a 12v source? (i already have an AEM wideband connected).

I have an electronic.. http://prosportgauges.com/amber-white-prem...st-gauge-2.aspx

I like it because you can set it to sound an alarm if you overboost.

 

The Prosports are nice my buddy has 3 in his saab I hava a stri dsd boost gauge for my supercharged s2k i love mine and its easy to install

 

Mechanical gauges are a thing of the past. I can't imagine any motor fluids being piped through my firewall and up to my dash.

Modern gauges work by an electronic sensor (pressure or temperature or whatever) mounted close to the source. In Deceptions case he has a small sensor mounted on his intake manifold and connected to the line that connects to his FPR.

The sensor converts the signal to volts (or resistance or whatever) and a wire passes through the firewall to a matching gauge inside your cabin. The gauge is pre-calibrated to read the signal from the sensor and displays it in an acceptable format, be that C or F for temperature or PSI or KgCm2 for pressure or whatever.

Some gauges are so hi-tech they actually convert the signal back into physical movement and make a needle swing to a specific spot on a face inscribed with numbers to simulate an old style gauge.

As to whether or not the sensor requires power or not that is specific to the type of gauge but in my experience most boost gauge sensors require two lines: +5V and signal; and these are provided by the gauge itself.

 

Thanks AUS
