There is a guy who races at my local track in Camarillo who uses a CO2 tank for blow off. He likes it and says it will last him at least 3-4 months. I don't know the actual capacity but the tank is about 3ft tall or so. I think it's about $35 (maybe more) or so to get it refilled. It's not a bad way to go as you don't need any power to run it, it makes no noise, and needs no maintenance.
I tried my portable compressed air tank but you don't get enough capacity at the normal 120psi compression. The CO2 tanks are normally compressed at 3,500psi or so.
I just recently picked up this compressor from Sears
. I like it but wish the tank capacity was a bit more. I compared it to the one with the 3 gal horizontal cylindrical tank but it was much heavier to lug around and didn't have any regulator or gauges. Mine isn't too loud compared to many others I've heard at the track.
My only problem now is the start up current draw is a bit much for the 1,000watt generator my race buddy has. It needs a compression release or starting capacitor to help out and not bog the generator down too much. The generator will handle it fine with no other load but when we've all got chargers going it will trip it.
