Hey Chris, remind me next club meeting to pop my hood. I used two of 'em to reduce load and have a backup just in case. Two also speeds air-up. I found that on a hot day, one compressor would trip its thermal protection when mounted under the hood (engine heat) at about tire #3's finish. With two, no problemo. Another alternative would be a muffin fan of some sort.
Can't seem to kill the dang things. I gave up on the screw-on valve fitting it came with after having to hold the hose 'just right' above Central City in blistering cold wind, last run with JadeRunner. He was done (using CO2) when I was on tire #3. It takes a little longer than CO2, but not that much longer, and I could jettison the bulky bottle and gain interior room and lose weight.
