They're not the fastest things in the world so more the better. I can inflate (1) 32in tire from 10psi to 32psi in 5min with two compressors. You can imagine how fast 1 would be.

 

Here's how I mounted my viair 450 - I had to shift the cruise control box as well. It's super tight under the hood, but you should be able to find room for the small caddy compressor.

 

They are slow, but they're durable. They will air up my 7 Gallon tank to 100psi in about 20 minutes. I do this on the road so they have air passing over them to help keep them cool. After the trail it takes about 15 minutes to air all 4 of my 33x12.5 from 10psi to 32/23psi.

 

Cool. I guess I didn't realize they were electric...I should've read that first. :pat:
