Ive recently fitted a Prosport Boost and Oil Temp gauge and found a few things a bit tricky, so ive decided to come up with a fitting guide to help future members get along alot easier.
These gauges ive installed are Electrical were most that ive seen installed are mechanical, there is a small difference on the boost gauge which is that the vacuum pipe attaches to a sensor before it attaches to the gauge on an electrical gauge, on a mechanical gauge the pipe attaches straight to the gauge.
TOOLS REQUIRED:
Torx screw bit (for intercooler)
Stanley knife
10 zip ties
Screw driver ( for pushing through the rubber grommit)
Electricians tape
PARTS REQUIRED:
Boost gauge
“T” piece
Sensor wire (electrical only)
Power wire
2 – 3m of Tubing depending on if you are installing an electrical or mechanical gauge.
Gauge pod or holder for attaching to the dash or rev counter.
Spare lengths of 12v wire for extending the + & - wire attachments.
1. First thing to do is remove the intercooler, Remove the 4 screw’s on the intercooler cover and then 4 more screws which are the on the clamps either side. You will then see this……
The part circled ^^ is the Fuel Pressure Regulator………..
You need to unplug that black wire from underneath and plug your “T” Piece into it (make sure it’s a good solid fit to the “T” Piece).
Now cut a piece of tubing about 10cm’s long and attach it to the other side of the “T” piece and reconnect it to the Fuel Pressure Regulator, the pic below is with the “T” Piece and the 10cm tubing and im now going to connect it to the FPR,
Now connect your remaining long piece of tubing to the last part of the “T” Piece and route it to the inside of the car, I used a rubber grommet as in the pic below….
As you look at that pic on the left the grommet through the firewall is to the left of that silver bar and under a flimsy piece plastic, I then located it under the dash which is the pic to the right and gently forced a screw driver through the grommet.
Now, as you have a screw driver through the grommet from the inside out, attach the tubing to the screw driver and tape it on, gently pull the tubing through the hole
Mechanical Gauge…….
Now you have the tubing through the firewall plug it into the back of the gauge and wire the power up to a suitable live such as the cigarette lighter surround for the lights on the gauge.
Electrical Gauge…..
You will have 2 wires provided that plug into the back of the gauge, power wire and sensor wire…..
Sensor wire: this will have 3 wires inside Black, Red, White. Simply connect them to the same colour wires on the end of the sensor provided and attach the tubing that you routed to the inside of the car to the other side of the sensor.
Power wire: as this is not long enough I got some suitable 12v wire and lengthened it as necessary, The Red wire goes the the positive terminal on the battery and the Black wire goes to the Negative terminal on the battery.
(I could not get a ring terminal for the size of the battery’s terminal’s to match the thickness of the wire so I used a spade connector and clamped it under each bolt on the terminal’s).
Then you are left with 1 more wire which is for the lights of the gauge, I connected this to the live wire of my cigarette lighter, light ring.
And there you have the gauge working.
The MAX PSI from a stock car will be around 11PSI, and the MAX PSI from a modified car will be around 16PSI with a 15% pulley.
THIS GUIDE IS A GENERIC GUIDE FOR FITTING GAUGES AND THERE MAYBE SOME DIFFERENCES WITH DIFFERENT MAKES/ MODELS.
Also the prosport boost gauge came with a small inline air filter as in the pic below which I just cut the tubing when routed and plugged either end in to the filter.
OIL TEMPERATURE GAUGE
TOOLS REQUIRED:
13mm Socket Set
Screw Driver
Electricians tape
10 zip ties
Trolley/ Bottle jack
2 Axle stands
clean container for oil
PARTS REQUIRED:
Oil Temp gauge
Sensor
Sensor Wire
Sensor Holder as in the first pic below. (for replacing the Oil sump screw)
Gauge pod or holder for attaching to the dash or rev counter.
Spare lengths of 12v wire for extending the + & - wire attachments.
FOR THIS INSTALL BASICALLY FOLLOW THE BOOST GAUGE INSTALL GUIDE FOR EVERYTHING ELSE APART FROM THE DIRECTIONS AS BELOW!
Jack the car up, and place the car on 2 axle stands at the front.
Using the 13mm socket remove the Oil sump screw and drain the oil into a suitable clean container if you are going to re-use the oil.
Now connect your sensor to the sensor bolt and screw it in to the oil sump, as per the 2nd pic.
^^^^ This bolt is the sensor holder and the replacement for the oil sump screw
^^^^ This pic is the sensor and bolt fitted the oil sump!
Attach the sensor wire to the gauge and route that wire to the oil sump sensor and connect them together
Attach the power wires as per the boost gaug
Refill the engine with the oil or new oil if you prefer!
This is a pic of the bracket i used to attach the gauges to the rev counter, i had to trim the top edges to match the shape of the dash so it was all neat and tidy!
Hear is a pic and video of the gauges fitted to the car!
That looks absolutely brilliant, cracking job you've done there! How much did those 2 gauges set you back because i might consider doing it myself after seeing how good that looks!
Thanks mate... not sure now i got them direct from prosport if you google the name then it will come up but dont forget about import tax as that adds a bit of money on
Thanks bud, just had a look and they're pretty good value actually...about $50 for the boost gauge and $40 for the oil temp gauge..might have to invest in them...will definitely be using your guide to install them if i do!
Sorry but if you connect the power wire to the positive terminal of the battery won't it stay open even if you turn off the car??
I assume of that because how it is possible for a car alarm to stay active when switch off the car.
Sorry but i didn't get that,and because the last few days iam looking for 12v switched power wire could you explain me again where you made your power connection.
i would like to buy the gauge with boost and battery volt from newminimania, is mechanical, the sensor for the boost isn't necessary right? because there isn't mentioned and doesn't come with the gauges kit
thanks
