I like the idea of the ac compressor but I like having the ac working. Is there a way to hook up a second ac compressor (from my parts truck) on the 22re in a first gen 4RUNNER?
If you have an AIR pump as part of your emissions system and don't have emissions testing, you could fab some brackets to mount a 2nd AC compressor there.
You can go cheap with a Superflow MV50 as long as you aren't running 35" tires or bigger. Superflow has bigger units for larger tires but I have aired up 33" tires in under a minute each with my MV50, it takes me longer to air down than up. I paid about $75 locally for mine. What I like best about it is it is complete, and portable. Amazon.com: Master Flow MF-1050 Tsunami High Volume Portable Air Compressor: Automotive
