Got the compressor wired in today. Well half of it. The power supply is all finished, but half the dash is still hanging out as I am laying in some cabling for other things and I want to do all of that in one go. So more on that as it comes together. But I couldn't resist rigging the switch up so that I could give the pumps a go. The first thing you hear is the fans kick in. Pretty neat having their own cooling system.
I pulled the core from one of the tyres and let it go flat. Now remember these are 315.70.17 = 35" They're a foot wide. So completely flat, core out with vehicle sitting on it. In 60 seconds the tyre was up and no longer visibly rising so if necessary, drivable. It took 2 mins exactly from flat to blow it to 30 psi and never even got warm, nor did it change note at all. Again, just remember the volume in one of these things. It's not the same as 285.70.16 getting to 30 psi. I'm happy with that. I think with a tank it would be quite a thing. It has it's own pressure switch in it so plumbing in a tank would only need plastic pipe. 10 minute job. Ish. It would also take the tank to 200 psi and with the cfm, replenishment would be pretty rapid. But I will sleep on that. It's an expense, weight and space I'd rather save. I can't see me blowing tyres up every five minutes.
