So. Most people use 12 compressors instead ov engine driven or nitrogen. I just got a new alternator with 200 amps. So lack of power is not a problem. I'm curently using 2 Thomas comp. Into a 5 gallon tank, and I have the nitrogen in case i have to show off a little bit. So what do you think is better. Buying 4 more thomas compressors or get 2 good viar or one big one?????? :uh:
