The 2020 Ford Explorer ST serves as a robust foundation for automotive enthusiasts aiming to merge practicality with high performance. Among the community of dedicated modifiers, the ‘Silver Sonic’ project stands out as a remarkable example of meticulous enhancement and ambitious goals. This article delves into the extensive modifications undertaken in the ‘Silver Sonic’ build, highlighting the strategic upgrades that have propelled this vehicle towards exceptional performance benchmarks.
1. Genesis of ‘Silver Sonic’
The journey began with the unfortunate demise of a 2015 3.5L Twin-Turbo Explorer Sport, which led the owner to embark on a new venture with the 2020 Explorer ST. Motivated by a passion for racing and a vision to push the vehicle into the 9-second quarter-mile bracket, the ‘Silver Sonic’ project was initiated. Early achievements included a 1.774-second 60-foot time and a quarter-mile run of 12.62 seconds at 108.89 mph, laying a solid foundation for future enhancements.
2. Performance and Off-Road Modifications
To elevate the Explorer ST’s capabilities, a series of performance-focused modifications were implemented:
-
Whipple Mega Cooler Intercooler: This upgrade enhances the cooling efficiency, ensuring optimal air intake temperatures for improved engine performance.
-
FENFABrication Performance Test Pipes/Downpipes: These components reduce exhaust backpressure, facilitating better turbo spool and increased horsepower.
-
Thermal R&D 3″ Cat-Back Exhaust System: This system improves exhaust flow and adds a more aggressive exhaust note, complementing the vehicle’s enhanced performance.
-
AFE Momentum GT Cold Air Intake System: By increasing airflow to the engine, this intake system contributes to improved throttle response and power output.
-
Turbosmart BOV Kompact Dual Port: This blow-off valve ensures reliable pressure release, enhancing turbocharger longevity and performance.
-
H&R Lowering Springs: These springs lower the vehicle’s center of gravity, improving handling and reducing body roll during cornering.
-
ID Speed Rear Differential Brace: This brace provides additional support to the rear differential, enhancing durability under high-performance conditions.
-
FENFABrication Suspension Components: Upgrades such as the Rear Subframe Lockout Kit, Vertical Links, and HP Rear Toe Links improve suspension rigidity and alignment, resulting in better handling and stability.
-
NGK Spark Plugs: High-performance spark plugs ensure efficient combustion, contributing to smoother engine operation and power delivery.
-
AED RTD+ Device & HP Credits: This tuning device allows for precise calibration of the engine control unit, optimizing performance parameters.
-
ZFG Custom Tuning with DSM Upgrade: Custom tuning maximizes the benefits of the hardware upgrades, ensuring harmonious and peak performance.
3. Exterior Modifications
Aesthetic enhancements were also a priority, with modifications aimed at achieving a sleek and aggressive appearance:
-
OEM Ford Roof Rack Delete Parts: Removing the roof rack results in a cleaner roofline, reducing drag and enhancing the vehicle’s streamlined look.
-
70% Window Tint: Applying a 70% tint all around, including the windshield, provides a uniform appearance while offering UV protection and privacy.
4. Future Aspirations
The ‘Silver Sonic’ build is an ongoing project with ambitious plans to further enhance performance:
-
Nostrum Stage 3 Fuel System with Stage 3 Injectors: Upgrading the fuel system will support higher power outputs by ensuring adequate fuel delivery.
-
CR Performance Stage 5 Turbos: These turbochargers are expected to significantly increase horsepower and torque, pushing the vehicle closer to its 9-second quarter-mile goal.
-
RSA 1060R Stage 1 Transmission: Enhancing the transmission will ensure it can handle the increased power and provide reliable performance under high-stress conditions.
-
Driveshaft Shop Rear Axles: Upgraded rear axles will provide the necessary strength to withstand the increased torque and power delivery.
5. Community Engagement and Track Performance
The ‘Silver Sonic’ project has been actively showcased within the Explorer ST community, with regular updates and track performance reports. The owner has shared insights and experiences, contributing to the collective knowledge and inspiring fellow enthusiasts. Track sessions have provided valuable data, informing further modifications and tuning adjustments to achieve optimal performance.
