My own compressor comparo.........

I said some time ago that I would eventually get around to doing a comparison between the MaxAir (3 years old) and the several month old Mega Grunt (which looks identical to the Maxair). I have the 2 units coupled together side by side on a sheet of plywood. They feed air into 2 tanks mounted on the cargo barrier. One is 3 litre (I swear it's the only 3L thing I'll ever have in my Patrol!!! hahaha) and the other is a 4L gas bottle. There is also a fair amount of air hose/tube front front to back and up onto the roof; but as this is only the 6mm "Festo" type stuff, that wouldn't add much to the capacity.

I started by totally bleeding the tanks/system. Then, using the switches on the compressors themselves (which are both normally left in the "ON" position), I filled the system to the ARB's pressure switch's cut-off point (around 95psi indicated on my "A" pillar-mounted gauge). The Mega Grunt was done first and took 1m27s with a terminal temperature of 42.5oC. I bled the system again and did the same proceedure with the Maxair; 1m12s and 41.3oC.

The 2 units combined managed to do the job in 37seconds and the temps were 32.5 for MegaGrunt and 34.6 for the Maxair.

Not much in it at all. Probably of little interest to the gallery anyway, but hey, I was bored, okay!? Also, just checked out the Load compensation arm/spring on the rear axle of the Patrol too. It had never been altered despite having had 2" then 5" raised coils since purchase. I made up a steel bar with 4 holes in it to raise the bracket, so that the piston on the device is not constantly forced inwards. I'm assuming this is what others have done?
