i think ive made my mind up… shocker s4 train horns,5 gallon tank,480c compressor (or 495c) and 200psi… 
should sound ok yeah?
any idea when this kit will be back in stock? just my luck…
These kits are discontinued.
It is not necessary to run them at 200psi since we have made the upgrade to a 1/2" valve.
A Shocker 540 will be PERFECT.
Please PM me if you have any further questions.
yea 150psi is plenty with 1/2in everything
we can still sell you the 548 if you would like but then send you a lower psi pressure switch as well if you would like to just have the more constant duty compressor.
thanks for the replies guys, im a little confused now… so which is the more constant duty compressor? 480c or 495c and what does constant duty mean?
sorry you,l have to excuse me this is all new to me…
just trying to get my head around it all…
Both air compressors are Constant Duty. HOWEVER, the 480c has a constant duty of 100% at 100psi and the 495c has a constant duty of 100% at 175 psi. So much better.
Also, the 495c is ViAir’s fastest air compressor.
