      Best Design. There are plenty of superchargers on the market for Mustangs, but only the V-3 Si from Vortech offers the advanced design of a centrifugal compressor.

        2015 Vortech

        The install is not for the faint of heart as you will be cutting up your car! I took a weekend to install it, about 8-10 hours total. I modified my existing cold air to work with the kit. Cold starts are a little rough for a few seconds but other than that it runs flawlessly. Power is incredible! runs a little stronger than stock up to 3500rpm and then you had better hold on! MPGs have improved and intake temps are still within a few degrees of ambient. The AF readings bounce around quite a bit more than they used to, I will address that when I get a proper tune.

      5 Top Rated Questions

      I see someone in the reviews saying you have to cut up your car. Is this true? Do I really have to cut things in the engine bay?

      • The Vortech V-3 SI Supercharger system is a relatively simple install with only minor modifications needed for installation. The only modification you are making is small cuts to PVC hoses and trimming your radiator shroud which can be accomplished with basic power tools.

      does this kit passes smog? or which of your kits do?

      • This Vortech V-3 Si Supercharger is not CARB Compliant and will not pass smog. The Roush R2300 670HP Supercharger, item 384386, is CARB approved. The Edelbrock E-Force Stage 1 Street Supercharger Kit, item 393440, and the Ford Performance 670HP Supercharger Kit, item 387372, are both CARB approved as well.

      How does this S/C compare to a twin screw. After reading all the pros and cons of each it seems both have advantages. With the performance package I hit 3500 rpm quick in 1st and 2nd gear. Does the Vortech compete with a twin screw?

      • They both have their pros and cons, the centrifugal supercharger like this vortech, can best be described as a belt driven turbocharger, wherein, it still has a "turbo like" impeller to compress the air at a high rate of speed, but is driven entirely by the engine belt system. A twin screw system uses 2 "screws" to pull in and compress the air also driven by the belt, a centrifugal style supercharger will compete and out-perform a twin screw depending on how the vehicle is set up.

      Does this kit work if u already had added a Power pack #3 and the proper tune for it in your car, what do i have to do? Back to stock and then do this?

      • You would need to have another tuner tune the vehicle after install of the supercharger.

      What fuel system upgrades are included with the complete kit rather than the tuner kit? I already have a tuner, would I need the fuel components for this to work?

      • The complete kit includes a V-3 Si-Trim Centrifugal Supercharger, High-Flow Fuel Pump, Fuel Management Unit (FMU), High-Flow Bypass Valve, Reusable High-Flow Air Filter and a Programmer. Depending on your application and your power goals you may need a fuel pump and injectors.
