Section 1: Engine Performance – Unleashing the HEMI's Fury
The 6.4L HEMI is the heart of the 2013 SRT8, and it's a prime candidate for performance upgrades. Here's a look at some popular options:
-
Cold Air Intakes (CAI): A CAI replaces the factory airbox with a less restrictive system, allowing the engine to draw in more cool air. This results in improved throttle response and a noticeable increase in horsepower and torque, particularly at higher RPMs.
- Benefits: Increased horsepower and torque, improved throttle response, enhanced engine sound.
- How-To (Simplified): Disconnect the mass airflow sensor, remove the factory airbox, install the CAI following the manufacturer's instructions, and reconnect the sensor.
- Considerations: Choose a reputable brand, ensure proper fitment, and be aware that some CAIs may require a tune.
- Examples: K&N, AFE Power, Mopar.
-
Cat-Back Exhaust Systems: These systems replace the exhaust piping from the catalytic converters back, offering improved exhaust flow and a more aggressive exhaust note.
- Benefits: Increased horsepower and torque, improved exhaust flow, aggressive exhaust sound, enhanced aesthetics.
- How-To (Simplified): Disconnect the exhaust from the catalytic converters, remove the factory exhaust system, install the cat-back system using the provided hardware.
- Considerations: Consider the desired exhaust note (loud vs. mild), material (stainless steel is more durable), and ease of installation.
- Examples: Borla, Corsa, Magnaflow.
-
Performance Programmers/Tuners: These devices allow you to remap the engine's computer (ECU), optimizing parameters like fuel injection, ignition timing, and throttle response for increased performance.
- Benefits: Increased horsepower and torque, improved fuel economy (when driven conservatively), customizable performance settings.
- How-To (Simplified): Connect the tuner to the OBDII port, follow the on-screen instructions to download the stock tune and upload the performance tune.
- Considerations: Choose a reputable tuner with custom tuning options, understand the risks of modifying the ECU, and consider professional tuning for optimal results.
- Examples: DiabloSport, HP Tuners.
-
Headers (Long Tube or Shorty): Headers replace the factory exhaust manifolds with individual runners for each cylinder, significantly improving exhaust flow. Long tube headers offer the greatest performance gains but require more extensive modification.
- Benefits: Significant horsepower and torque gains, improved exhaust flow, enhanced engine sound.
- How-To: Requires professional installation due to complexity and potential modifications.
- Considerations: Requires professional installation, may require modifications to the exhaust system, may trigger check engine lights without proper tuning.
- Examples: American Racing Headers, Kooks Headers.
-
Forced Induction (Supercharger or Turbocharger): For the ultimate power upgrade, consider a supercharger or turbocharger kit. These systems force more air into the engine, resulting in dramatic horsepower and torque increases.
- Benefits: Massive horsepower and torque gains, significant performance improvement.
- How-To: Requires professional installation due to complexity and extensive modifications.
- Considerations: Very expensive, requires professional installation and tuning, may require internal engine upgrades for reliability.
- Examples: ProCharger, Whipple Superchargers.
Section 2: Handling and Suspension – Carving Corners with Confidence
The 2013 SRT8 handles well for an SUV, but its weight and high center of gravity can limit its performance on the track or spirited driving. Upgrading the suspension can significantly improve handling and reduce body roll.
-
Lowering Springs: Lowering springs reduce the ride height, lowering the center of gravity and improving handling.
- Benefits: Improved handling, reduced body roll, enhanced aesthetics.
- How-To (Simplified): Remove the factory springs and install the lowering springs, usually requiring a spring compressor.
- Considerations: Choose springs with a moderate drop to avoid excessive ride harshness, consider adjustable shocks for optimal performance.
- Examples: Eibach, H&R.
-
Performance Shocks/Struts: Upgrading the shocks and struts can improve damping and control, resulting in a smoother ride and better handling.
- Benefits: Improved handling, reduced body roll, enhanced ride quality.
- How-To (Simplified): Remove the factory shocks/struts and install the performance units.
- Considerations: Choose shocks/struts that are compatible with your lowering springs, consider adjustable shocks for fine-tuning.
- Examples: Bilstein, Koni.
-
Sway Bars (Anti-Roll Bars): Sway bars connect the left and right wheels, reducing body roll during cornering.
- Benefits: Reduced body roll, improved handling, increased stability.
- How-To (Simplified): Remove the factory sway bars and install the performance units.
- Considerations: Choose sway bars that are appropriate for your driving style, consider adjustable sway bars for fine-tuning.
- Examples: Eibach, Hotchkis.
-
Adjustable Control Arms: These allow for fine-tuning of suspension geometry, correcting alignment issues caused by lowering the vehicle.
- Benefits: Corrected alignment, improved handling, reduced tire wear.
- How-To: Requires professional installation and alignment.
- Considerations: Requires professional installation and alignment.
Section 3: Braking – Stopping Power and Control
The factory Brembo brakes on the 2013 SRT8 are excellent, but they can be further improved for track use or aggressive street driving.
-
Performance Brake Pads: Upgrading to performance brake pads can improve stopping power and reduce brake fade.
- Benefits: Improved stopping power, reduced brake fade, enhanced pedal feel.
- How-To (Simplified): Remove the factory brake pads and install the performance pads.

Stainless Steel Brake Lines: These lines replace the factory rubber lines, reducing brake pedal flex and improving brake feel.
- Benefits: Improved brake pedal feel, reduced brake fade, enhanced braking performance.
- How-To (Simplified): Replace the factory brake lines with the stainless steel lines, requiring bleeding of the brake system.
- Considerations: Requires proper bleeding of the brake system after installation.
-
Big Brake Kits: These kits include larger rotors, calipers, and pads, providing a significant increase in stopping power.
- Benefits: Significant increase in stopping power, improved brake fade resistance, enhanced aesthetics.
- How-To: Requires professional installation.
- Considerations: Expensive, requires professional installation, may require larger wheels to accommodate the larger brakes.
- Examples: Brembo, Wilwood.
