how much is too much

i am getting either the hb 150psi or the 200psi complete sir setup without the horns
im ganna get a firetruck horn from a junk yard(short on cash)
is 200psi too much for a air horn

save the extra cash and get a conductors special 200psi kit

go to ur local fire house and ask them how much psi they put to their air horn…

a stuttertone is run at 65 psi…never put a grover horn over 115psi…

i ran my grover 24" at 150 for over a year still sounds great

a 24’ is fine…but not a stuttertone
