And yes, you can run it without the blower, assuming it still works. It'll be a LOT quieter, but still enough to irritate the neighbors (I don't speak from experience or anything...

I'm going to reiterate Aaron's question...what part of MN are you from?? I live right in Southwest Minneapolis. Good to see more and more MN siren nuts joining! Maybe one of these days I'll have to push all the sirens out into the yard and host a "siren nerd" BBQ or something like that.

Oh, and here's my 1000 with a bank teller blower reversed to make a supercharger. Nothing like a REAL Tbolt blower, but it certainly makes the beast rumble your chest! This is running on 120vac ("Level 1")
