The Ford Explorer has long been celebrated for its versatility, seamlessly blending family-friendly features with robust performance capabilities. However, the notion of an Explorer dominating the drag strip was once unthinkable. Enter the 2020 Ford Explorer ST—a game-changer equipped with a twin-turbocharged 3.0-liter EcoBoost V6 engine and a 10-speed automatic transmission. This model has shattered expectations, proving that SUVs can hold their own in high-performance arenas. A standout example of this transformation is David London’s Explorer ST, which has achieved remarkable quarter-mile times, firmly establishing itself in the annals of automotive performance history.
The Evolution of the Ford Explorer ST
From Family SUV to Performance Powerhouse
Traditionally, the Ford Explorer was synonymous with practicality and reliability, catering primarily to families and adventure enthusiasts. Performance variants were rare, with exceptions like the Saleen XP8 offering glimpses of the model’s potential. The introduction of the Explorer ST in 2020 marked a significant shift, as Ford infused the lineup with a performance-oriented model that didn’t compromise on utility. Equipped with a twin-turbocharged 3.0-liter EcoBoost V6 engine and a 10R60 10-speed automatic transmission, the Explorer ST delivered impressive power and responsiveness, laying the groundwork for enthusiasts to push its capabilities even further.
David London’s Pursuit of Speed
The Genesis of a Record-Breaking Build
David London, an automotive enthusiast with a penchant for performance, saw untapped potential in his 2020 Ford Explorer ST. While the stock configuration offered commendable performance, David envisioned transforming his SUV into a machine capable of rivaling dedicated sports cars on the drag strip. To realize this vision, he enlisted the expertise of Evolution Performance, a renowned tuning and performance shop known for pushing the boundaries of automotive engineering.
Comprehensive Modifications for Optimal Performance
The collaboration between David and Evolution Performance led to a series of strategic modifications aimed at enhancing the Explorer ST’s power, efficiency, and drivability. Key upgrades included:
-
Turbocharger Enhancement: Replacing the factory turbochargers with CR Performance Stage 5 turbos to significantly increase airflow and boost pressure.
-
Fuel System Upgrades: Installing a Nostrum Stage 1 high-pressure fuel pump and matching injectors to meet the increased fuel demands of the enhanced turbo system.
-
Air Intake Optimization: Integrating an AFE cold air intake and a Velossa Tech Big Mouth Ram Air Snorkel to improve air induction efficiency.
-
Exhaust System Refinement: Implementing SPD Performance catted downpipes and a Thermal R&D Performance 2.5-inch cat-back exhaust system to enhance exhaust flow and reduce backpressure.
-
ECU Tuning: Collaborating with Adam at ZFG Racing to develop a custom tune that harmonizes the new components, optimizing performance and reliability.
These modifications were meticulously chosen and implemented to create a balanced system where each component complemented the others, resulting in a cohesive and powerful performance package.
Achieving Record-Breaking Performance
Dominating the Drag Strip
With the modifications complete, David took his Explorer ST to the drag strip to assess its newfound capabilities. The results were nothing short of extraordinary. The SUV consistently delivered quarter-mile times in the 10-second range, with runs recorded at 10.94, 10.95, and 10.96 seconds, all reaching speeds of 125 mph. These times were achieved without any modifications to the 10-speed transmission, highlighting the robustness of the factory drivetrain when paired with strategic performance enhancements.
Implications and Community Impact
David’s achievements have resonated throughout the automotive community, challenging preconceived notions about the performance potential of SUVs. His Explorer ST serves as a testament to the capabilities inherent in modern engineering and the possibilities unlocked through thoughtful modification. This accomplishment has inspired fellow enthusiasts to explore similar upgrades, fostering a growing interest in high-performance SUVs and expanding the horizons of what these vehicles can achieve.
Technical Insights into the Modifications
Turbocharger Upgrade: CR Performance Stage 5 Turbos
Upgrading to CR Performance Stage 5 turbos was a pivotal decision in enhancing the Explorer ST’s performance. These turbochargers offer increased airflow and higher boost capabilities compared to the stock units, resulting in substantial gains in horsepower and torque. The design of these turbos ensures efficient spooling, maintaining responsiveness and minimizing lag, which is crucial for both daily driving and competitive racing scenarios.
Fuel System Enhancements: Nostrum Stage 1 Components
To support the increased air intake from the upgraded turbos, the fuel system underwent significant improvements. The Nostrum Stage 1 high-pressure fuel pump and injectors provide the necessary fuel flow to maintain optimal air-fuel ratios under higher boost conditions. This ensures complete combustion, maximizing power output while safeguarding engine health.
Air Intake and Exhaust Modifications
The combination of the AFE cold air intake and Velossa Tech Big Mouth Ram Air Snorkel enhances the volume and quality of air entering the engine, contributing to more efficient combustion and increased power. On the exhaust side, the SPD Performance catted downpipes and Thermal R&D Performance 2.5-inch cat-back system facilitate smoother expulsion of exhaust gases, reducing backpressure and improving turbo efficiency.
ECU Tuning: The Role of ZFG Racing
Custom ECU tuning by ZFG Racing was integral to harmonizing the new components. The tune adjusts parameters such as fuel delivery, ignition timing, and boost pressure to optimize performance while ensuring reliability. This bespoke calibration allows the Explorer ST to operate seamlessly with its enhanced hardware, delivering consistent and safe power gains.
Challenges and Solutions in the Modification Process
Balancing Performance and Reliability
One of the primary challenges in modifying a vehicle to this extent is maintaining a balance between performance gains and long-term reliability. Each component must be carefully selected and integrated to ensure that the increased stresses do not compromise the vehicle’s integrity.
