I have a 89 Fox with a Paxton SN93 supercharger. I'm looking to purchase a polished discharge tube with bung for bypass valve. My question is, will a Vortech or Powerdyne tube fit on my SN93? If so, what models? I'm having a hard time finding exactly what I'm looking for. I've read that the tubes on superchargersonline.com are for the Novi and don't fit the SN's very well... Not sure if that's true though... Thanks in advance.
