Every Road Leads Home said:Speaking of air compressors, what is everyone using for a portable compressor for tire inflation?
The MV-50 is a good basic compressor designed to hook right to battery terminals. NO ciggy plug crap. It pulls 16 amps minimum, which would melt a ciggy plug and blow fuses. I cut off the clamps and use 45 amp anderson powerpoles instead, but can return the clamps as they now have the powerpole too.
I did not like the screw on tire chuck, and wound up tapping the head for standard 1/4 inch NPT air fittings, and used a better airhose and locking tire chuck which I made passive
there was no Stress relief where the wires entered the backside of the unit, and the wires were joined with crimp nuts which I am no fan of
The Airfilter inlet holes were obstructed with flashing left over from the mold, which caused me to not use the air filter on initial uses. Mistake
One can also see the cylinder only touches heatsink in 4 spots, with much larger dead air spaces which would greatly slow heat conduction from cylinder head. I filled these with high temp grease to better conduct heat from cylinder head and piston.
I also added a 80MM fan to blow over head for further heat evacuation.
That yellow hose is just a harbor fright hose. I wound up not using any quick release fittings as I saw no point in removing the hose from the head. I later bought a smaller diameter hose that stretches easier and uses better strain relief.
The MV-50 is a good tool, but some spit and polish can make it into a great tool.
I left the 14awg cable, but if the time to fill tires is a factor, then it can be sped up by using 10AWG wire from battery to relay in the endcap to minimize voltage drop.
Mine pulls a minimum of 16 amps, but this can go higher with higher voltages applied, like when running the engine.
If one upgrades the tire chuck/ fittings, it must be passive, so that it cannot build up pressure in the airhose, and blow the airhose, or the piston cup, or worse.
