My home-made York OBA system with two Grover truck horns off a Peterbuilt. The system is pressurized to 150 PSI, has a 5 gallon tank, and the horns are regulated down to 100 PSI. The theoretical maximum would be 120 PSI for the horns, but they are plenty loud as it is.
get some hadley ambassador's for that thing then you would be rollin man!
