A couple of weeks back I got a present from the missus, an ARB on-board high output (single motor) compressor. Then last week I managed to get to Couplers in Malaga to spend a small fortune on air fittings to make what I want happen.
On Sunday I finally got around to fitting it. I decided to fit it in between the vacuum canister bracket and the firewall on the passenger side of the engine bay. After spending a long while looking at the best way to mount it, I finally decided the best angle and direction needed my battery isolator to move. So it went to the firewall with minimal effort, a slightly longer cable, and made a lot more room for the compressor.
With the isolator moved I had heaps more room on the vacuum canister bracket. I mounted the compressor with the filter facing down and using the top bolt from the vacuum line to hold the compressor to the plate. Next I simply drilled the holes where they were needed for the other 3 holes and mounted it to the plate with some difficulty.
With the compressor mounted to the plate, the vacuum bracket went back in the car and all vacuum lines were connected back up. The fittings I had bought were moved to provide the best layout around the vacuum lines and the bulbar air outlet was mounted along with an over pressure relief drain.
From the compressor there is a Nitto fitting, a pressure switch and a pressure gauge to keep an eye on things, The Nitto fitting usually is connected to some 3/8 heater hose which is joined to the front air fitting with the overpressure drain and main Nitto air outlet. The idea being that I can always get air straight from the compressor if the airline to the bulbar fails.
I stripped the supplied wiring harness down to its basics as I didn’t need very much cabling at all as there was a point on the battery isolator to get my voltage from. With all the cabling removed from its taped loom, I cut and adjusted the wiring to suit my needs. The fused cable is now about 40cm long and the earth is the same. The switch wiring was also adjusted and a few crimps and cabling meant that all of the cables were the right length, not a one size fits all. All of the airlocker wiring was removed as I don’t have or plan on fitting air lockers to my car, and if I do, I would rather wire them myself.
I have 6m of air hose which is plenty to get from the bulbar to the rear tyres and all I need to finish is get an air chuck.
