Supercharger SRT Intake Manifold Dodge RAM TRX 1500 53011
part number 53011100AD (or variations within the 53011 series) identifies the IHI Twin-Screw Supercharger and Integrated Intake Manifold Assembly for the 6.2L HEMI® V8 Hellcat engine used in the Dodge RAM TRX.
Unlike a traditional naturally aspirated engine, the TRX’s intake manifold and supercharger are a single, integrated “charged air” unit. The manifold acts as the baseplate that bolts directly to the cylinder heads, housing both the rotors and the intercooler bricks.
Technical Specifications: TRX Supercharger
| Feature | Details |
| Supercharger Type | Twin-Screw (IHI) |
| Displacement | 2.38 Liters ($2380\text{cc}$) |
| Max Boost | $approx$ $11.0\text{ PSI}$ (Standard Pulley) |
| Max RPM | $14,600\text{ RPM}$ |
| Drive System | 10-rib dedicated belt drive |
1. Integrated Charge Air Coolers (Intercoolers)
Inside the 53011 manifold housing sit two Air-to-Liquid Intercooler Bricks.
-
Function: These cool the compressed air before it enters the combustion chamber.
-
TRX Specifics: The TRX uses a high-capacity cooling circuit to maintain performance during high-ambient desert temperatures.
-
Inspection: Check the coolant “inlet/outlet” nipples on the rear of the manifold. If they are bent or showing crusty residue, the internal bricks may be leaking.
2. Critical Components & Sensors
When sourcing or selling this assembly, ensure these auxiliary parts are intact, as they account for significant replacement costs:
-
The Bypass Valve (BPV): An electronically controlled actuator that recirculates air under low-load conditions to prevent “surging” and improve fuel economy.
-
MAP/IAT Sensors: The manifold has integrated Manifold Absolute Pressure and Intake Air Temperature sensors. The TRX uses a high-speed TMAP sensor to provide real-time data to the PCM.
-
The Snout (Bearing Retainer): This is the front section where the pulley attaches. Check for “play” in the shaft or a “clattering” sound at idle, which indicates worn bearings or a failing isolator.
3. Inventory & Installation Notes
-
Gasket Surface: The TRX supercharger uses specialized reusable rubber-over-steel intake gaskets. Always inspect the mating surface for “pitting” or deep scratches that could cause a vacuum leak.
-
Port Injection: While the supercharger provides the air, the fuel injectors are mounted directly into the lower manifold “runners.” Ensure the fuel rail mounting bosses are not stripped.
-
Compatibility: While the TRX 53011 unit is physically similar to the Challenger Hellcat supercharger, the throttle body orientation and vacuum routing are specific to the RAM’s engine bay layout.
Technical Inspection for Resale
| Component | What to Look For |
| Rotor Coating | Inspect the rotors through the inlet. The black Teflon coating should be smooth. If you see bare aluminum or deep gouges, the unit has ingested debris. |
| Pulley Condition | Ensure the pulley is the stock diameter ($approx$ $80\text{mm}$/$3.15\text{“}$). If it is smaller, the unit has been “over-spun,” which may reduce bearing life. |
| Coolant Ports | Check for signs of “oil” in the intercooler ports, which would indicate a blown internal seal. |
