    • The Vortech V-3 Si-Trim Supercharger is a complete kit with everything needed for installation of a stock vehicle. Depending on what you are looking for out of your vehicle, the suggested products could vary. We would recommend speaking with your tuner regarding what you are looking for and discussing if that is something that could be tuned for.

    Do they make a blow off valve for this? Also is the hp you listed to the wheels or motor?

    • Power gains with the Vortech V-3 Si-Trim Supercharger are listed at the flywheel. A blow off valve is typically not installed on a supercharged engine, as it is not needed with a supercharger, especially at more conservative boost levels, such as the 7-9psi of this kit. Vortech does make bypass valves for their supercharger kits, however these are designed for cars putting out 12+PSI and 20+PSI and would not work well on lower PSI kits.

      Great Supercharger!

      My friend got this supercharged installed in his fox and it has instant boost. Me and him were both tickled to death about the performance gain. Plus it looks pretty under the hood.
