Installing ProChargerâ€™s intercooled supercharger system for the S550

Since the days of the original pushrod 5.0-liter engine, superchargers and Mustangs have been fast friends. One of the companies that have fostered that friendship is ProCharger. As the company that brought intercooled supercharging into the mainstream and has innovated other technologiesâ€”like self-contained and programmable-ratio superchargersâ€”itâ€™s no surprise that ProCharger is now offering supercharger systems for the 2015 Mustang GT
The ProCharger S550 HO kit includes everything you need to perform the install, right down to a preloaded tune on a DiabloSport handheld tuner. You can also opt for a tuner kit and leave out the tuner, but youâ€™ll obviously need to work with someone for a custom tune to ensure it safely runs to its full potential.
â€œProCharger wanted to start with a â€˜clean slateâ€™ on this system, and not just adapt something from the previous body style to work, as others have,â€ Erik Radzins, who handles both calibrations and social media at ProCharger, explained. â€œVirtually every single item changes from the previous system. About the only thing they share is the fuel injector.”
â€œThis clean-slate approach helped the customer in many ways. For starters it created the HO System that uses the shared drive belt of the engine, and used a sized appropriate intercooler that would fit the needs of most 2015 customers,â€ he added. â€œThis cuts down on costs of the system, and will still allow for big power numbers of over 700 rear-wheel horsepower to be achieved easily. We didnâ€™t want to have to force a customer into buying a system that was overkill for what they needed. If they are looking for over 800 horsepower, they can purchase or upgrade to our Stage 2 system.â€
Weâ€™ve been anxious to see how the latest system mates with the new Mustang, and when Erik offered to install the HO system in a customerâ€™s garage on a totally stock car, we jumped at the chance to share it with you. This system is based on ProChargerâ€™s stalwart P-1SC supercharger. The SC stands for self-contained, so thereâ€™s no tapping of the oil pan to lubricate the unit. The system is a true bolt-on.
â€œInstallation is easy! That is the only way to describe it, just look at the tools involved and its obvious that if a guy can change his own oil and spark plugs, he can install this blower kit,â€ Erik said. â€œTaking off the front bumper is the hardest part, and even that just takes a few moments.â€
â€œWe have the easiest kit to bolt on a car. We make crazy good power numbers with no heat soak and the system is a bargain,â€ he added. â€œNothing is even close, price-wise.â€
Of course, with the kit installed the car was tested on ProChargerâ€™s in-house Mustang chassis dyno. Running readily available pump gas, which isnâ€™t the greatest mixture during the winter in Kansas City, the car put down 530 rear-wheel horsepower with nothing more than the supercharger and the preloaded tune. With that calibration, the numbers compare favorably with the 2011-2014 Coyote with a ProCharger HO system.
â€œThe numbers on a 100-percent stock car are a tiny, tiny bit less per pound of boost (no matter what system you have) due to the changes in the exhaust, intake manifold and cams in the new Coyote motor. However with custom tuning, and exhaust changes, people are getting crazy good numbers out of the systems on just 8 psi.â€
The HO kit is quite affordable, for a modern-car power adder, at around $5,600, and the tuner kit is a bit less for those that bring their own supporting mods to the table. If you want more power, you can obviously step up to the Stage 2 kit, which is good for 540 to 600 rear-wheel horsepower. This system offers numerous upgrades, including a dedicated eight-rib belt drive and an intercooler that is 75 percent larger.
â€œPower numbers from the HO system have been right in line with the systemâ€™s design. Customers are already making over 700 rear-wheel horsepower with D-1SCs and mild boost levels. Surely it wonâ€™t be long before we see someone put an F-1 on an HO system and raise that bar even higher. The Stage 2 system was really designed for those that are wanting to play in the 800 horsepower range and beyond.â€
A few of ProCharger dealers, including Blow-By Racing have recorded impressive numbers with the HO kit and custom tuning. We hope to circle back on this car, asÂ Joseph Rees wants to upgrade his 2015 and increase the boost. In the mean time, follow along as Erik installs this system and check out the results.
