2012-2013 Boss 302 ProCharger Stage II Intercooled Complete Supercharger Kit 1FR312-SCI

Huge Power Potential in a Highly Efficient Supercharger System

A ProCharger centrifugal supercharger system is great, bu one that makes even more horsepower and torque over the standard offering is even better. The ProCharger Stage II Intercooled supercharger system for the 2012 to 2013 Boss 302's 5.0L V8s ups the ante over ProCharger's standard High Output kit by adding a performance 3-core air-to-air intercooler and new tubing that gives the system more out of the box power and much more potential horsepower and torque when used with other modifications. This powerful system can add up to 215 horsepower to your Boss's total output, with a ton more room to grow when you add on modifications like long tube headers and their requisite custom tuning. ProCharger's Stage II Intercooled Mustang Supercharger System is still based around ProCharger's legendary P-1SC-1 centrifugal head unit that gets supported by the upgraded intercooler, more aggressive tuning, and other modifications to push its output up much farther than a more standard centrifugal supercharger system. The Stage II kit is the perfect platform for an out-and-out performance Boss 302 build and anyone who needs some extra room to grow.

High-Tech Internally Lubricated Head Unit

The system's P-1SC-1 head unit has a fantastic reputation for both reliability and power, and is one of the most advanced centrifugal head units on the market. Each P-1SC-1 has a high-quality, high-strength, and highly advanced impeller design that's CNC machined from aircraft grade 7075 billet aluminum. The impeller is spun by a precision-cut gear set with a an extremely impressive 4.10:1 step-up ratio that helps reduce hesitation and improve acceleration response. ProCharger can even upgrade the unit with a set of even quieter Helical cut gears at additional cost. The gears come packed into a 6061-T6 billet aluminum casing that helps keep noise down while allowing excellent levels of heat dissipation and strength. The P-1SC-1 is completely self-contained and self-lubricated and does not require you to tap your Boss 302's oil pan in order to run oil feed or drain lines. The head unit comes with a full machined mounting bracket that bolts right on to the front of your Boss's 5.0L V8. The head unit is available in a standard satin or polished finish. The bracket can also be polished at additional cost.

Aluminum Three-Core Air-to-Air Intercooler with Charge Piping

The kit's extra horsepower and torque comes courtesy of its upgraded three-core intercooler. This high-quality aluminum intercooler dissipates much more heat than the High Output system's more standard intercooler and completely blows systems without intercoolers out of the water. The intercooler installs underneath your Boss 302's radiator in its lower grille opening to maximize airflow and cooling potential. Along with the intercooler itself, the Stage II system comes with larger and more efficient tubing leading both in and out of the intercooler which provides immense levels of air volume to pour into your Boss 302's 5.0L V8. Providing all this extra air is a revised intake system with a large high-flow air filter and tubing that allows the P-1SC-1 head unit to bring in all the boosted air it needs to give your Pony huge levels of horsepower and torque. The Stage II kit comes with a new coolant reservoir for proper fitment of all its hardware.

New Fuel Injectors, PCM Tuning, and Hardware

Bringing the system together is a suite of fuel system upgrades and PCM tuning that's been carefully designed to provide your Mustang's motor with big power gains. Each kit includes a full set of 52lb/hr fuel injectors that provide enough fuel for the increased volume of air being forced into your Boss 302's cylinders. ProCharger's PCM tune comes preloaded on a fully-functional tuner that uploads the tune to your Mustang through its OBD-II port. The ProCharger PCM tune changes key aspects of your Boss 302's computer settings to handle the tremendous amount of power and new upgrades that the Stage II system brings to the table. Each of these impressive supercharger systems all come with a complete set of installation hardware and detailed instructions.
