i run a stock toyota AC compressor i got for 10 bucks to a tank and it takes me 5 mins from the time i hit the switch to air up all 4 of my 38s .... :\ i think i have like.. 15 bucks in my whole OBA setup. somthin to look into... i dont like the power tanks or running co2 because once it goes empty.. its empty
15 bucks seems a little cheap. you clearly had parts lying around which im sure dont. or your not running an oiling system, theres a cheaper way to set it up. if i were to run a toy compressor i would be sure to carry a spare because if they don't get enough oil there toast. but when working properly they air tires up fawking quick
