2005-2009 Roush Stage 4 Upgrade Kit

2005-2009 Team JDM Roush Stage 4 Upgrade Kit

Add over 40 HP at the wheels to your 2005-2009 Roushcharged Mustang with the Team JDM Stage 4 Kit. Factory Roush Supercharged Cars such as the Stage 3 or 427R model mustang come with a base 435 HP at the engine powerplant that simply consists of a ROUSHcharger Supercharger Kit. The ROUSHcharger Kit is available for purchase from Roush allowing you to provide the same performance on a factory based Mustang GT. With 435 HP at the engine your starting off with a great base for performance. Team JDM will get your car up to 475 HP with our Stage 4 Kit. This is done with a combination of custom tuning, better induction, and more boost pressure. Team JDM includes a Cold Air Induction Kit that uses a 90mm Mass Air Housing that provides more flow and performance. Also a smaller diameter Supercharger Pulley is used to spin the supercharger faster generating more boost. With the smaller pulley on the supercharger a larger Idler Pulley is also included to keep the belt from slipping. Colder Spark Plugs are included in the package to ensure an efficient spark with the extra boost entering the engine. All this increase in air flow requires a custom tune to be made and Team JDM offers that using an SCT X4 Programmer. The tune is built specifically for your car and the parts you have installed on it! This will result in an improvement of nearly 40 more HP at the tires, better throttle response, and reduced 1/4 mile times of nearly a full second!!
