Power Bypass kit for 86-93 SC Mustangs. HP Coated. The POWER BY-PASS KIT was designed because of the need for a discharge tube that would utilize the VORTECH Super Bypass (which we feel is a must with boost levels of 14 lb or more) on S-R-T-Trim Superchargers. While the POWER BY-PASS KIT holds the Super Bypass (which is a first) AF went one step further and made it a higher volume discharge tube for the higher boost levels which will also increase efficiency. Bypass shown but not included.
