Already called Turbodyne on it. I said..."I'd like to order your 1500". They said "what do you want one for?" I asked for the sales dept. and they don't have one. Turbodyne was bought out by Honeywell in 98-99ish and then they split up again recently. That latest that I have heard is that Turbodyne builds the electronics that run the system and Honeywell builds the turbos themselves....Honeywell turbo division is located in El Segundo if anyone else wants to give it a shot. Supposedly these things put out close to 8psi with no spool.
