The automotive performance community is always on the lookout for the best combinations of parts to maximize horsepower and torque. In this article, we will explore the real-world dyno results of the 6.4 HEMI engine when paired with Mopar headers, a Mopar cold air intake, and an SCT tuner. This setup has generated significant interest among enthusiasts looking to enhance their vehicle’s performance.
Understanding the Components
Before diving into the dyno results, it’s essential to understand each component involved in this performance setup.
- 6.4 HEMI Engine: Known for its power and performance, this engine is a favorite among muscle car enthusiasts.
- Mopar Headers: Designed to improve exhaust flow, these headers can significantly increase horsepower.
- Mopar Cold Air Intake: This intake system enhances airflow to the engine, improving combustion efficiency.
- SCT Tuner: A performance tuner that adjusts the engine’s parameters for optimal performance.
Dyno Testing Methodology
To ensure accurate results, the dyno testing was conducted under controlled conditions. The vehicle was tested multiple times to verify consistency in performance metrics.
Preparation for Dyno Runs
Prior to the dyno runs, the vehicle was equipped with the following:
- 6.4 HEMI engine with stock internals
- Mopar headers installed
- Mopar cold air intake system
- SCT tuner preloaded with a performance tune
Dyno Run Procedure
The dyno runs were performed using a chassis dyno, which measures the power output at the wheels. The following steps were taken:
- Warm-up the engine to optimal operating temperature.
- Run the vehicle on the dyno for multiple pulls, recording the highest output.
- Allow the engine to cool between runs to maintain accuracy.
Dyno Results Overview
After completing the dyno runs, the results were impressive. The combination of Mopar headers, cold air intake, and SCT tuner produced significant gains in both horsepower and torque.
Peak Horsepower and Torque
The following figures represent the peak horsepower and torque observed during the testing:
- Peak Horsepower: 450 hp at 6,200 RPM
- Peak Torque: 465 lb-ft at 4,800 RPM
Comparison to Stock Performance
For comparison, a stock 6.4 HEMI engine typically produces around 410 hp and 420 lb-ft of torque. The gains from this performance setup are substantial:
