I accidentally posted this under newbies…not sure I posted in right location…sorry admins…
I have my eyes on a Conductor’s Special kit…
But cant decide on the 248 or 540…and i’m hoping feed back can help me out.
I want the loudest of the two for sure and I dont really have a preference to the length of blast time… (unless I should?)
Any and all advice will greatly be appreciated
Thanx for reading…
Here’s my response from the other thread. Whether you care about honk time depends on what/how you intend to use the horns. Most people want more honk time.
Thanx for your reply…
So if I wanted a longer blast time…
Should I got with the 2gal tank @200psi or
the 5gal tank @ 150 psi…
You should go for a 5 gallon tank @ 200psi 
I think some recent testing showed that the Shockers are not much (if any) louder at 200 psi. If you wanted the most honk time with any size tank, run 200 in the tank & regulate down to 150.
To keep it simple, I’d just do 5 gallons at 150.
Oh yeah… I should’ve added that:o. If you go 200psi then you really need to add a regulator. I don’t think HB warrants the Shockers for 200psi use anyway.
What sort of CFM would you need for a regulator to run a 4-chime set of shockers?
Quite a few people have bought an inexpensive regulator from McMaster Carr
225cfm 1/2" regulator with gauge - 4959K303
Bracket for regulator - 4910K98
^^ This.
Get the 540, run the tank to 175psi with the 175psi pressure switch (call HB when you do your order, they’ll let you swap items out and make sure to get your forum discount) then regulate it down to 120 to 150psi.
You’ll get well into 15 to 25 seconds of straight honk time. You might think, “Well damn, that’s not much.”, but once you hit than button to sound them off you’ll think different.

Thanks guys, just wondering. I have the Puma air compressor which won’t go above 135 PSI anyways, but maybe I could use it to fast fill the tank and then top off with an AZ or something.
The OB2 is a fantastic compressor.

Welcome to the forum! If you get the OB2, you won’t need the Puma. Oasis air compressors blow the doors off all the others.
Sorry to hijack your thread, OP. I shouldn’t have done that.
