That brings the installed setup to $825 + shipping the mounting kit from AU.......that's probably break-even with the price of an ARB twin after you fuss with the wiring and fuses for it.
Wouldn't you need to swap pulleys on either the AC/balancer or that compressor so they could all run on the same loop together?
Not sure I have an email to endless for more info.
GOOGLE ARB twin is not a reliable compressor add in a thermo cut out at 198° I would look elsewhere. A engine compressor is almost twice as fast as the ARB twin.
