Review COMP CAMS Hrt Camshaft Kit Dodge 5.7l/6.1l Charger fits HEMI

The **Comp Cams CK112-303-11 HRT Camshaft Kit** is a meticulously engineered performance upgrade designed to unleash the full potential of the legendary **Dodge 5.7L/6.1L Hemi engine**, whether it s running stock or under forced induction with a supercharger. This high-performance kit features **Comp Cams signature HRT (High-Rise Timing) profile**, which delivers a striking balance between **torque and horsepower**, making it an ideal choice for both street-driven muscle cars and high-RPM supercharged applications. The **112-degree lobe separation angle** ensures smooth valve operation while maximizing airflow, reducing pumping losses, and improving cylinder scavenging critical factors for supercharged engines where efficiency and reliability are paramount. Crafted from **high-quality forged steel**, these camshafts are built to withstand the intense stresses of aggressive valve springs, high RPMs, and the added load of forced induction, ensuring long-term durability even under extreme conditions. The **303-degree duration at 0.050-inch lift** provides a generous power band, extending peak performance well into the mid-to-high RPM range, where a supercharger thrives. This duration, combined with **1.11-inch lift**, allows for optimized intake and exhaust valve timing, enhancing both low-end torque and top-end horsepower key attributes for a supercharged Hemi that demands both pull and punch. Whether paired with a **Eaton Supercharger, Paxton blower, or another forced induction system**, this kit ensures that every cylinder receives maximum fuel and air, translating into **noticeable power gains, smoother throttle response, and a more aggressive exhaust note**. Comp Cams precision grinding and heat-treatment process guarantees consistent performance across all four camshafts, while the included **high-performance springs and retainers** (if applicable) help mitigate valve float, even at elevated RPMs. Perfect for both **builders looking to fine-tune their supercharged Hemi** and **enthusiasts seeking a substantial power bump**, the **CK112-303-11 HRT kit** is a proven performer that delivers measurable results without sacrificing reliability. Installing this kit requires careful attention to valve spring pressure and lifter clearance, but the rewards **increased horsepower, improved throttle response, and a more aggressive engine character** make it a standout choice for those pushing their 5.7L/6.1L Hemi to its limits.

### **Pros and Cons of the Comp Cams CK112-303-11 HRT Camshaft Kit for the Dodge 5.7L/6.1L Hemi Charger**

#### **Pros**

1. **Performance Gains** This kit is designed to significantly improve horsepower and torque by increasing valve lift and duration. The **112-degree lift** and **303-degree duration** (at 0.050") provide a substantial boost in airflow, especially when paired with a high-flow intake and exhaust system.

2. **Balanced Power Curve** The **303-degree duration** (at 0.050") offers a good mix of low-end torque and mid-range power, making it suitable for both street and mild strip applications. It won t be as extreme as a full race cam but will still provide noticeable gains over stock.

3. **Compatibility with Stock Engines** While this is an aftermarket cam, it is designed to work with stock 5.7L/6.1L Hemi engines (with proper supporting mods). It won t require a full engine rebuild, though some adjustments (like valve springs or lifters) may be needed for reliability.

4. **Good for Forced Induction (Turbo/Supercharger)** Since the 5.7L/6.1L Hemi is commonly turbocharged, this cam kit helps optimize airflow for boosted applications, improving response and power delivery.

5. **Reputable Brand** Comp Cams is a well-known manufacturer in the performance camshaft industry, offering reliable products with good support and warranties.

6. **Retains Some Stock Feel** Unlike extreme cams that make the engine feel "loose," this kit still provides a relatively smooth power delivery, making it suitable for daily driving with proper supporting mods.

#### **Cons**

1. **Requires Supporting Modifications** Simply bolting this cam on top of a stock engine will likely cause **valve float, excessive lash, or even catastrophic failure**. You ll need:

- **Upgraded valve springs** (or at least stock springs with a valve spring retainer upgrade)

- **Hydraulic or solid lifters** (if using hydraulic, ensure they re high-quality)

- **High-flow intake and exhaust** (to prevent vacuum issues)

- **Tuned ignition timing** (to avoid detonation)

- **Proper fuel delivery** (upgraded injectors or fuel pump if running high boost)

Without these, the engine will struggle to handle the cam s demands.

2. **Not a "Plug-and-Play" Solution** Unlike some cam kits that claim to be "drop-in," this one will require **engine tuning** (either via a standalone ECU or a tuner like Haltech, Link, or AEM). A stock ECU will not properly support this cam.

3. **Potential for Rough Idling or Misfires** If not properly supported, the engine may develop **valve float, excessive lash, or timing issues**, leading to rough idle, misfires, or even engine damage.

4. **Limited Longevity Without Full Build** While this cam is durable, running it on a stock engine (without supporting mods) will **reduce its lifespan** and increase wear on critical components like lifters, valves, and camshaft bearings.

- **Valve springs** (or a full valve train upgrade)

- **Lifters** (if switching from stock)

- **Intake & exhaust upgrades**

- **Tuning services** (if not doing it yourself)

- **Possible fuel system upgrades** (if running high boost)

This can add **$1,000 $3,000 ** to the total cost, depending on what else you modify.

6. **Not for Beginners** If you re not experienced with engine modifications, this kit is **not a simple weekend project**. Proper installation, tuning, and maintenance are crucial to avoid damage.

### **Ending Conclusion & Recommendation**

The **Comp Cams CK112-303-11 HRT camshaft kit** is an **excellent choice** for those looking to **significantly increase power** in their 5.7L/6.1L Hemi Charger, whether naturally aspirated or forced induction. It strikes a **good balance between performance gains and drivability**, making it suitable for **street, strip, and mild boost applications** as long as the engine is properly supported.

**However, it is not a "set-and-forget" upgrade.** If you install this cam without the necessary supporting modifications (valve springs, lifters, intake/exhaust, and tuning), you risk **engine damage, poor performance, or even failure**. This kit is best suited for **intermediate to advanced tuners** or those willing to invest in a **full engine support package**.

#### **Who Should Buy This?**

**Turbocharged Hemi owners** looking for a **mid-range cam** that improves throttle response and power.

**Naturally aspirated Hemi builders** who want a **substantial power bump** without going full race.

**Those with tuning experience** or access to a **professional tuner**.

**Builders who are already upgrading other components** (intake, exhaust, fuel system).

#### **Who Should Avoid This?**

**Stock-engine owners** who expect to just bolt this cam on and drive away.

**Beginners** without experience in engine modifications or tuning.

**Those on a tight budget** this cam is just the start; supporting mods will add significant cost.

**Those running extreme boost** without proper fuel and cooling upgrades.

### **Final Recommendation**

If you are **serious about performance** and willing to **invest in the necessary supporting mods**, the **Comp Cams CK112-303-11 HRT camshaft kit** is a **strong choice** for your 5.7L/6.1L Hemi Charger. However, **do your research, consult with a tuner, and ensure your engine is properly prepared** before installation.

- **Upgraded valve springs** (or a full valve train)

- **High-flow intake and exhaust**

- **A reliable tuner** (Haltech, Link, or AEM)

- **Proper fuel delivery** (if running boost)

- **Oil cooling and filtration upgrades** (for longevity)

If you re unsure about any part of the process, **consult a professional** before making the purchase. This cam will **deliver impressive power gains**, but only if the engine is ready for it.
