      More Power! The stock GT Mustang came with a respectable 300 Horsepower and 320 lb/ft of Torque from the factory, but after installing a Vortech System you will be planting a healthy 420 Horsepower and 385 lb/ft of Torque to the pavement. That is 120 more horsepower over stock!

      Complete Kit. This Vortech Mustang Supercharger System comes with all the required parts needed to upgrade your Steed to a fire breathing Beast. The kit features Fuel management upgrades including a high-flow fuel pump, high-capacity fuel injectors, and a DiabloSport Predator Tuner to re-flash the stock ECM.

      Application. This Satin Vortech Supercharger System is specifically designed for use on the 2005 to 2008 GT Mustangs.

      Technical Note. ECM reprogramming will be required when additional aftermarket parts are added including but not limited to MAF meters, cold air intakes, smaller supercharger pulley, headers and exhaust modifications.

      Please Note: Vortech Supercharger System are built to order by Vortech for our customers. Because of this there can be a 5 to 7 day lead time on orders.

        5 2006 GT - AlanV Installation Time: Weekend

        Highly recommended

        I went with the non-inter cooler cus of the power. I don't need a 500hp monster. My car is faster than anything I meet on the street. Nice steady big block power. The instructions were vague on some steps but common sence prevailed. The tune is great but I do have a stumble/flat spot when taking off slow. It bucks bad like someone learning to drive a stick. I will figure it out. 2006 GT all stock, but not any more. Love it.

      Is it absolutely needed that I run and intercooler with this? Is it absolutely needed that I run and intercooler with this, or is that something I can add down the road for more pony's? I intend on buying this kit very soon. Need help with the details!

      • The reason intercooling is recommended is because an intercooled supercharger is more than twice as efficient as a non-intercooled system. So with half the PSI, you can lay down the same horsepower as a non-intercooled system. If you're going to spend the money, my advice would be to spring for an intercooler.

      worth it at 57000 miles? im at 57000 miles and some people say my engine will blow up if i get this. so would it be worth it to buy this?

      • Hi, This Vortech Supercharger System - Satin only puts out 9-10 PSI, on a well taken care of 57K engine that low amount will not blow it up.

      What intercooler do you recommend? If its not included which one do u recommend?

      • Two types are available: air to air and water to air. In the air to air, the boosted air (after the supercharger) moves through a large air cooler (like a radiator) mounted under where the front license plate mounts. AM sells this type made by Mishimoto. You will need piping from the blower to the intercooler back to the intake. In the water to air type, again the boosted air is pushed through a core or box like plenum that has is radiator like so the hot boost air is pushed through this cooling core and then into the intake manifold. The sc coolant circulates much like a radiator with a water pump located inside the bumper cover and the radiator portion is mounted below where the front license plate mounts. The pump is electric and operates when the ignition is on. This is the type I have. You would have to talk with AM to get one or order it from Vortech. You will need a custom tune for either. Superchargers are the best way to max out your s197. You can easily get 450-480 rwhp with an intercooler. Good Luck!

      I have made some some modifications to my 2007 GT, long tube headers, cat-less X-pipe, Shelby GT500 throttle body, Roush CAI, SCT for life tunes. I get that the CAI will have to go, but will the SCT tuner be able to make tunes for a supercharger and will I have to get rid of the GT500 throttle body?

      • The tune that comes with this kit is a canned tune. It may not necessarily accommodate all the modifications that you have made. It is advised to get a dyno tune to ensure that everything is working properly and you are getting max performance. Depending on the tune, you may need to go back to the stock throttle body.
