The "Inner Tim Allen" in me has surfaced again. This time during an air horn installation.
The roots of this one lay in the end-of-trail event all H2 owners know: The 20-40 minute tire refill.
After blowing about 45 minutes airing up... I began the search for a better way. I found that most 12vDC air pumps only put out around 10L max.
Knowing there had to be a better way, I tapped into my friends in south china an found it. I found a shop in south china that makes a 150L per minute air pump. It runs on 12vDC and draws about 60 amps.
So of course... I ordered one.
Then I thought about it and decided that it would go even faster if I have an air tank.
Having just installed the Gobi rack... I had lots of space up top.
Knowing I was thinking of installing an air horn, I called and asked what size air tank was suggested. The horn vendor sugegsted a .5 gallon tank.
So I bought a 5 gallon tank. I figured a 900% reserve couldn't be a bad thing.
I also bought a Viair 145 psi pressure switch.
And a set of horns....
I spent the better part of tonight fabricating a mount to put the horns in a semi-protected place on the Gobi rack.
The black spray paint is drying on the new mounts right now.
I'm going to run 3/8 hose from the tank to the horn. I hope it can breath through that...
Report on the expected carnage tomorrow after parts are dry and installed....
