closer performance than i thought, i have an original thumper, its been not very well looked after , left out in the rain, still goes, i dont think i would shell out the extra $$ for a "possibly" more reliable compressor
My first compressor was one of the original kings thumper max’s. It did me well but I used it a lot and in the rain and heat. Eventually died when I was trying to use it at about 50 degrees celsius
Price is a big Factor! How many Kings can you buy for a ARB,? Buy a $12 pressure 90-110psie switch and mount it internally on the manifold of the Kings, MaxiTrac etc, they are all pretty much the same, and ya have a cut off switch, instead of having to switch it on and off all the time, I did the hose upgrade so I get a full volume flow and its even faster, so its 1/4" all the way now! Plus the Anderson plug upgrade and also ya want to go to 4guage cable, use min 120amp Anderson Plug and ya good to go, I also swap out the stock hose from the manifold with a Nitto Coupler, so its another link out of the chain and std volume across all connections and hoses! I'll add a Morflate dual hose at some stage or make my own! Still not half the cost of an ARB. That said in cab or tray mount, then ARB might be a better solution. But these are very easy mods to make to any 300PL dual air compressor. I do have a friend with an even more expensive ARB, the portable with air tank, its about $1500 here, its is very fast, haven't speed checked her since I did my mods, but I know I'm faster than before, hers is very quick though again she is only inflating 33s and I'm doing 3s and was only one wheel behind by the time she finished and that was running back and forth, switching the compressor on and off, which I don't do now and have a constant connection dia end to end, so will be interesting to see next trip. For those interested to do these mods, plenty of vids on you-tube how to do it, its not hard and def worth it, if going with the cheaper option. Just search Nappa or Morflate compressor mods on youtube, I went with the direct tapped option into my manifold with the pressure switch, the easier but more costly and more connections is a tee connection but its more to go wrong, bit ugly, bit more cost with fittings! Can be a bit scary drilling and tapping into the manifold by some, but take ya time, its pretty simple and clean. Good comparison though and vid.
