Pressure switch upgrade

Hi im running the S4 kit with a 7 gal tank,and a 380C with all 1/2" airline and valve except after the valve to the horns themselves,I was wondering would a 165-200 pressure switch make the horns any louder and still have that real locomotive pitch? Im running a 110-150 now Thanks alot.

Or even a 145/175 switch? Im seeing cases of people running 200 psi and their horns sound high pitched and it messes up the diaphragms.

200 dosent really mess it up at all…

but yes it will be louder…but no not as authentic

i did this when i upgraded to 1/2in everything at 200psi, personally it sounded like garbage… i actually downgraded to 110-150 because it has more musical sound

Yeah,thats kinda what I was thinking,so would 175 be about the same?

Anyone running a 175 pressure switch?
