Do ANY supercharger sellers ever reply to messages?

I have been totally unable to get so much as a peep out of any supercharger dealer, including Opcon and PSE.

I cannot find out what unit I need for my engine, I cannot get prices... nothing.

Opcon's Autorotor webpages are totally inaccessible... there are no links for it on Opcon's site, nor any mention of superchargers. Yet I HAVE seen the pages not long ago, but of course can't remember the URL.

Is there any customer service out there at all?

Opcon merged with another company back in 2005. All they do is R&D for Svenska Rotor.

PSE is a rebuild company. I will not go further to tell you what I truly think of them.

It sounds like you are searching for available products for a 3.3?
