The RAM TRX isn’t just a truck; it’s an apex predator. Out of the box, the 6.2L Supercharged HEMI V8 is a masterpiece of American engineering, churning out 702 horsepower and 650 lb-ft of torque. But let’s be real: if you’re reading this, "stock" is a four-letter word. You want more. You want to hear that supercharger whine louder, feel the truck pull harder, and leave everything else in the dust.

At DTX Performance, we live for the pursuit of power. Maximizing your TRX requires a strategic approach. It’s not just about throwing parts at the engine; it’s about creating a cohesive system that handles more boost, delivers more fuel, and stays cool under pressure.

Whether you’re looking to dominate the drag strip or just want the baddest truck on the block, here is your guide to maximizing your supercharged HEMI.

Push the Boost: Supercharger Upgrades

The heart of the TRX is that massive 2.4L Twin-Screw Supercharger. If you want more power, you need more air. The simplest way to achieve this is by changing the pulley ratio to spin the blower faster.

Upper and Lower Pulley Swaps

An upper pulley swap is one of the most cost-effective ways to see immediate gains. By reducing the size of the upper pulley, you increase the blower’s RPM relative to the engine's RPM, resulting in higher boost levels. When combined with a lower damper/pulley upgrade, you can see gains of 50 to 100+ horsepower.

Ported Blowers and Spacers

Beyond just spinning the blower faster, you want it to breathe more efficiently. Supercharger inlet porting smooths out the airflow, reducing turbulence and allowing the HEMI to gulp down air with less resistance. Adding blower spacer kits can also help with heat dissipation and plenum volume, providing a steadier stream of cool air to your cylinders.

Fuel the Fire: High-Performance Injectors

More air requires more fuel. If you increase boost without upgrading your fuel system, you’re asking for a lean condition that can end your engine’s life prematurely.

Upgrade to ID1050X Injectors

When you start pushing past the 800-horsepower mark, the factory injectors reach their limit. We highly recommend upgrading to Injector Dynamics ID1050X fuel injectors. These are the gold standard for high-performance HEMI builds. They offer incredible low-end drivability while providing the massive flow required at the top end of the RPM range.

Boost-A-Pump and Fuel Rails

To support those beefy injectors, you may need to look at your fuel pump's output. A "Boost-A-Pump" setup or a dedicated secondary fuel system ensures that the pressure stays rock-solid, even when you’re pinned at wide-open throttle.

Precision Control: Tuning and Engine Management

Hardware is only half the battle. To make all these parts play nice, you need a world-class tune. The TRX uses a locked PCM, which means the first step in your performance journey is often a PCM unlock service.

Custom Calibration

Generic, "off-the-shelf" tunes are fine for minor tweaks, but for a TRX with pulley swaps and injectors, you need custom calibration. A professional tuner will adjust your fuel maps, ignition timing, and transmission shift points. This doesn't just make the truck faster; it makes it more reliable.

At DTX Performance, we advocate for tuning that prioritizes a safe Air-Fuel Ratio (AFR) and manages heat effectively. Modern HEMI engines are robust, but they require precision to stay together under high boost.

The Instant Hit: Nitrous Systems

If you want a "party button," nitrous is the answer. Nitrous oxide is the ultimate power adder for enthusiasts who want massive power on demand without the constant stress of a high-boost pulley setup.

Dry vs. Wet Kits

For the RAM TRX, a "wet" nitrous system is generally preferred. This system introduces both nitrous and additional fuel into the intake tract simultaneously, ensuring the mixture remains stable. A 50 to 100-shot of nitrous can transform the TRX from a fast truck into a rocket ship, providing an instant cooling effect on the intake charge that helps combat heat soak.

Breathe Deep: Intakes and Exhaust

The more air you can get in and out, the more power you make. It’s that simple.

High-Flow Cold Air Intakes

Systems like the aFe Momentum or S&B intakes are popular for a reason. They replace the restrictive factory airbox with a high-volume housing and a massive filter. Not only do they provide gains of up to 25–30 horsepower, but they also let that supercharger scream. You’ll hear the whine from a block away.

Headers and Cat-Back Systems

The factory exhaust on the TRX is decent, but long-tube headers are where the real power is hidden. By reducing backpressure, you allow the supercharger to work more efficiently. Pair those headers with a high-flow cat-back system, and your TRX will finally sound like the monster it is.

Stay Cool: Reliability Upgrades

Heat is the enemy of performance. Supercharged engines generate an incredible amount of heat, and once the computer senses high temperatures, it will pull timing to protect the engine, killing your power.

Performance Thermostats

Installing a 180-degree thermostat, like the EvenFlo series, allows the cooling system to start cycling earlier. This keeps the engine at a lower baseline temperature, giving you more "headroom" before heat soak sets in during spirited driving or off-road sessions.

Heavy-Duty Belts

With increased boost comes increased strain on the supercharger belt. Don’t get stranded with a snapped belt. Upgrade to a heavy-duty green belt or a racing-grade alternative designed to handle the high torque loads of a modified HEMI.
