ProCharged Charger Picks Up 100 WHP At House Of Boost

Before the latest round of work, this ProCharged Charger already had a solid foundation. At the heart of the setup is a polished ProCharger P-1SC-1 centrifugal supercharger, a unit well known for its efficiency, reliability, and ability to support serious horsepower without excessive heat. Boost was set at 9.5 psi, a level that balances strong gains with long-term durability on a stock bottom-end.

Supporting mods on this ProCharged Charger are Stainless Works headers paired with high-flow catalytic converters, freeing up exhaust flow without turning the car into an emissions headache. From there, House of Boost handled custom in-house calibration, dialing the combination in on straight 93-octane fuel.

BTR Camshaft And Valvetrain Changes Unlock Big Gains

The real transformation came when House of Boost went deeper into the engine. A full camshaft and valvetrain upgrade was selected to better match the airflow demands of the supercharged combination. The cam choice was the popular BTR Truck Norris camshaft, paired with a complete supporting cast of components designed to keep everything stable at higher rpm and under boost.

Brian Tooley Racing supplied the supporting hardware in the form of a BTR .650 spring kit and matching BTR pushrods. Additional updates included Mopar MDS plugs, Mopar Hellcat lifters, and a Point 1 head stud kit to improve clamping integrity under boost. During teardown, the team discovered an issue with the exhaust valves. Rather than pushing forward and hoping for the best, House of Boost addressed the problem immediately, ensuring the engine was back together correctly before any hard pulls were made.

That attention to detail paid off. Once reassembled and tuned, the Charger went back on the rollers for comparison testing.

The ProCharger Speaks With Dyno Results

With boost held steady at 9.5 psi and fuel unchanged, the only variable was the cam and valvetrain package. The result was a massive 100-wheel-horsepower gain, shown clearly by the blue line on the dyno graph compared to the original green pull. Power increased everywhere, not just at the peak, giving the car a broader, harder-hitting powerband that better suits both spirited street driving and highway pulls.

Just as important, the tune was handled entirely in-house using HP Tuners with an RTD4 interface, allowing House of Boost to maintain full control over drivability, fueling, and spark under boost. The result is a Dodge Charger that makes 655 horsepower and 582 torque at the wheel, without sacrificing its cruiseability or reliability.

Built To Be Driven, Backed By Experience

Despite the dyno numbers, this ProCharger-powered Charger was never built to live on a trailer. The added cam chop gives it attitude at idle, but the combination remains street-friendly and dependable. On straight 93 octane, with boost kept in check and the valvetrain properly supported, the car is ready for spring cruise nights, weekend shows, and real miles on the road.

Projects like this ProCharged Charger highlight what happens when parts selection, calibration, and mechanical execution all work together. From identifying valvetrain issues during teardown to delivering a clean 100-wheel-horsepower gain without changing boost, House of Boost approached this Charger with the same mindset they bring to every build: make power the right way and make it last.

If you need a ProCharger installed or are looking to take an existing build to the next level, reaching out to House of Boost is a solid first step. Their in-house tuning, hands-on experience, and attention to detail make the difference between a dyno number and a car you can actually enjoy driving.
