Thread: Additional oomph for the EAS

Hey guys

You probably mostly know about the twin compressor setup I've got in the Blue P38 (twin OEM compressors in parallel - both run via EAS ECU control). So today I thought I'd compliment the Silver P38 with something similar.

Due to LPG gear mounted above the LHF shock absorber I was limited in locations to mount the second compressor, so this time I've done it differently.

I have a new ARB 12v compressor purchased a few years ago to compliment the Air Locker that was due to go into the Dmax I had at the time. Well I didn't end up fitting the locker to the Dmax, so had the compressor doing nothing (and no Dmax now to fit it to).

I mounted the compressor at the back of the drawer system in the rear. It runs directly into an inflation manifold that I made up, on a 100psi cut-off pressure switch. The compressed air runs through an OEM P38 air dryer (mounted in the compartment that provides access to the fuel release and AM/FM receiver), into this manifold, which feeds my tyre inflation quick-connect fitting under the bonnet, and the Ashcroft Locker in the rear diff.

From the manifold there is an air line running into the factory air tank beneath the P38 which is isolatable via inline ball valve.

The advantages I see to this setup are:

- Dry air regardless of which compressor is doing the chores.

- Allows the selective/optional use of OEM and ARB air compressors to inflate tyres or operate air tools (should the ARB compressor not meet your requirements on its own).

- Provides a backup compressor should the OEM compressor have a bad day (although limited to 100psi).

- Allows the air tank to be rapidly filled if drained or emptied for whatever reason.

- Allows the use of the OEM compressor to inflate tyres solely should the ARB unit die.

Thought I'd throw it up here as a point of interest. I haven't re-invented the wheel or changed the earth's rotation with this, but personally, I believe it's something that an off-roader should have when self-sufficiency is a big thing. It's like a Plan B and C.

I'll throw up a few pics tomorrow once I've tidied up the wiring. The aim was to have it subtle and neat, and I very much believe I've achieved that. Without physically jumping into the rear of the P38 you wouldn't know there lives a manifold, dryer, compressor or wiring loom in the back.

I'm not as quick witted as I was in my prime, so a come-back evaded me!

It'd make Rob proud. He did such an amazing job keeping everything invisible in this P38, I feel I must keep the legacy alive! There's a two-way and other nifty gadgets I've also mounted into the rear which even ninjas would have trouble hiding near.
