I’ve asked a few exorbitant things here before but after doing some more research, I found out the CFM delivery for York 210’s at higher pressures is simply too low for what I’m trying to do. That includes runbys in the hills, yes.
I ended up buying a massive two stage compressor that puts out 27.5CFM at 175psi, and I have an option of buying another if I really want to get crazy. I have not bought the motor for the compressor yet, which for most people would be a large horizontal gas motor. However, this is where my silly ideas come in again.
Why not run a dual compressor setup that is trailer axle driven? I see the potential issues right off the bat though. Trying to get 55CFM off a trailer axle would require about 30 horsepower in gas measurements, which is a lot. I’m thinking the trailer weight wouldn’t be more than 250 pounds, though I doubt that’s enough weight to compensate for potential wheel skidding, especially going over bumps or on dirt roads where the trailer wheels may temporarily lose compression with the roadway. I don’t think I’ve ever heard of a setup where someone drives their car with a trailer that has a motor producing resistance on the axle. It sounds like something that would be tried in Mythbusters, and I have no clue if it’s even safe or not. Even the guy at my local automotive store said it sounded like a ‘hold my beer’ scenario.
Essentially the setup would save me a lot of weight and space in the car if it was practical enough. A rather tiny sized trailer like this could fit in the back of my SUV and keep up with a 40 gallon air tank and there wouldn’t be nearly as much obnoxious engine noise. It’s that versus a 420cc gas motor powering a single compressor and 80 gallons of air plus having to stop a few times during the runby to regenerate air pressure.
That is probably what I will do in the end, but it’s an interesting thought if something like a trailer axle driven compressor was safe and possible. I certainly don’t have the funds to find out if it is or isn’t. I know something like this has been tried by one of the members here, but in more miniature fashion. Lol. Feedback would be appreciated. Thanks.
