Onboard air linking?

[DANMAL]

Hi all, I have a tigerz 11 thumper and a 9ltr tank that I am yet to install , I also have the hard range onboard air kit with the regular on it ( thanks Paul 👍👍) I was wondering if there was a way of linking the factory eas with the thumper and the 2 tanks, and if there may be any repercussions of doing so..

I'm thinking not to mess with the eas.. on the other hand the thumper pumps 160 ltrs p/m therfore in theory the the factory pump shouldn't be working so hard ..
Cheers

Mate is just adding more storage and more pumping capacity to the system, and long as the thumper has a pressure switch which cuts out around 150PSI, you should be fine

I plan on adding a wire that's tapped into the positive feed on the original compressor. Route it to a stitch in the cabin and then back to a relay. A fused feed from the battery will be activated via the relay, to power the 2nd compressor. That will enable extra pumping capacity when needed.

Sean, that sounds very much like what Keithy did. BTW has anyone heard from Keith recently? He seems to have gone VERY quiet.

If you have sorted all the leaks in the EAS system the existing setup is more than adequate...".. plug 'them' leaks"...

[DANMAL]

So if the eas does fair, I could switch it off and the thumper should still pump both tanks , therefore I could still pump bags manually?

The thumper's max pressure is 150 psi max so is the 9 ltr tank, what pressure switch would I need?
Does anybody know the operating pressure and the max pressure on the eas system. .

Not if you plan on extra storage capacity with an extra tank.

Sam. The eas pressure switch kicks the compressor in at around 100psi and stops it at around 145psi.

I would just hook the second compressor into the system, the fact it has it's own pressure switches means it will just come on and off when needed.

Not sure there is much advantage in a manual control, since you won't really know when it needs to switch on anyway.

If you think of it as two water pumps connected to a tank both with separate level switches then that is how the extra air pump would work, when the level (pressure) drops both pumps come on

I have seen Keithy a bit on FB, he seems to be enjoying spending time with his little girl :D

Yeah. What happened to Keith. Last I heard he was removing his engine. Maybe he's been absorbed with it.

The other thing I was contemplating regarding the 2nd air compressor, was how to link them together on the valve block inlet - air wise. I've asked this before, but I was leaning towards a NRV on each compressor, but would they end up chattering?

Hi, Just my opinion, all those tyre compressors are high volume with no load, as soon as you start putting pressure on the end they start slowing down. Generally 50psi is good to get from one, regardless of what the specs say. Any higher pressure, they get very slow, and then the heat gets to them. The thumpers had a very good review a while back, as they stayed the coolest over a longer period. The one I tested through work gave up the second time I used it, and kept throwing the thermal over load. If you were sure you wanted to hook up a 2 nd compressor, I would only have it there for emergency, or lower pressure, say up to 60psi, to help the standard to that pressure, then get it to turn off. I'm not sure of the pressure required to pump the suspension, but I have used my $70 eBay pump for a few years, it's quick, and have pumped a disco 2 suspension with it a few times. I would say it will be an expensive exercise to be running the thumper up to 100+ psi.
Only my opinion though.

I was thinking something like this is the go

VIAIR Corporation - 400C Compressor (P/N 40040) (http://www.viaircorp.com/400C.html)

Steve

[davidsonsm]

Yep Steve. My preferred choices are the viair or the boss. They have good duty cycle and are fit for purpose temp wise. The thumper is massive to locate under the bonnet.

[DANMAL]

Thanks for the input guys, I think I might just keep them separate, let the eas do its own thing and leave the thumper with the 9L tank in wheel well, that way I can use it to pump bags if things go sour.
Any ideas what pressure switch to safely use if the 9L tank is max 150 psi and so is the thumper?

[davidsonsm]

Something around 145psi stop should be bang on. Might as well squeeze as much air in as possible.

That's exactly what I was thinking, didn't know if it were safe though or stress out compressor

[davidsonsm]

If they rated to 150psi - then it should produce it. The thermal switch will prevent any damage - assuming it has one.
