The 2020 Ford Explorer ST emerges as a formidable contender in the performance SUV arena, boasting a twin-turbocharged 3.0-liter EcoBoost V6 engine that delivers 400 horsepower straight from the factory. While this power is impressive for a family-oriented SUV, some enthusiasts envision pushing these boundaries even further. One such visionary is Kevin Krupski, who has meticulously transformed his Explorer ST into a 657-wheel-horsepower (WHP) powerhouse, capable of completing the quarter-mile in just 10.94 seconds. This article delves into the comprehensive journey of modifying the Explorer ST, highlighting the challenges, innovations, and triumphs encountered along the way.
The Genesis of the Build
Kevin Krupski’s journey began with the acquisition of a 2020 Ford Explorer ST, intended primarily as a family vehicle. Initially, his modification plans were modest, focusing on aesthetic enhancements like window tinting and a cat-back exhaust system. However, the unforeseen circumstances of the COVID-19 pandemic provided Kevin with ample time to explore the burgeoning community of Explorer ST enthusiasts. Engaging with online forums and discussions, he discovered a collective ambition to unlock the untapped potential of this SUV. This communal enthusiasm ignited Kevin’s determination to elevate his Explorer ST beyond conventional expectations.
Initial Modifications: Laying the Foundation
Performance Tuning with ZFG Racing
The inaugural step in Kevin’s modification journey involved enhancing the vehicle’s engine performance through software tuning. Collaborating with ZFG Racing, he aimed to extract an additional 100 horsepower from the stock engine. The process entailed meticulous data logging and iterative adjustments to the engine control unit (ECU). The culmination of this effort was a custom tune that significantly amplified the vehicle’s power output, providing a thrilling driving experience and setting the stage for more ambitious modifications.
Custom Exhaust System by FenFabrication
Seeking to improve exhaust flow and auditory presence, Kevin turned to FenFabrication for a bespoke exhaust solution. The challenge lay in the limited aftermarket support for the Explorer ST, necessitating a custom approach. The result was an intricately designed exhaust system that not only enhanced performance but also emitted a robust and aggressive exhaust note, embodying the vehicle’s newfound vigor.
Advancing Performance: Comprehensive Upgrades
As Kevin delved deeper into the realm of high-performance modifications, he recognized the need for a holistic approach, addressing various components to achieve a harmonious balance of power, reliability, and drivability.
Upgraded Turbochargers
To substantially increase horsepower, Kevin opted for aftermarket turbochargers capable of delivering higher boost pressures. These turbos facilitated greater airflow into the engine, resulting in a remarkable surge in power output. The selection of these turbochargers was strategic, considering their potential to support power levels exceeding 1,000 horsepower, thereby future-proofing the build for subsequent enhancements.
Enhanced Fuel System
Recognizing that increased air intake necessitates a corresponding augmentation in fuel delivery, Kevin upgraded the fuel system comprehensively. This included installing high-flow fuel injectors and an upgraded high-pressure fuel pump, ensuring the engine received an optimal air-fuel mixture under elevated performance demands. This upgrade was pivotal in maintaining engine stability and efficiency during high-load conditions.
Whipple Intercooler Installation
To combat the inherent heat generated by forced induction, Kevin integrated a Whipple intercooler into the system. This component effectively reduced intake air temperatures, mitigating the risk of heat soak and preserving consistent performance during extended periods of spirited driving. The intercooler played a crucial role in enhancing the engine’s thermal efficiency and longevity.
Transmission Reinforcement
The substantial increase in power necessitated fortifying the drivetrain to handle the augmented torque. Kevin collaborated with Level 10 Transmissions to enhance the stock 10-speed automatic transmission, incorporating a Circle D torque converter. These modifications improved the transmission’s durability and responsiveness, ensuring seamless power delivery and accommodating the heightened performance demands.
Achieving the 10-Second Quarter-Mile
The culmination of these meticulously planned and executed modifications was the Explorer ST’s ability to complete the quarter-mile in 10.94 seconds, a feat traditionally reserved for dedicated sports cars and supercars. This achievement not only underscored the effectiveness of the modifications but also challenged prevailing perceptions about the performance capabilities of SUVs, positioning Kevin’s Explorer ST as a formidable contender in the high-performance automotive landscape.
Overcoming Challenges and Innovating Solutions
Kevin’s journey was fraught with challenges, primarily stemming from the limited aftermarket support for the Explorer ST platform. This scarcity necessitated innovative solutions and bespoke fabrication, particularly in developing components like the exhaust system and sourcing compatible performance parts. Kevin’s proactive engagement with the enthusiast community and collaboration with specialized fabricators were instrumental in navigating these obstacles, resulting in a build that was both unique and exemplary.
Community Engagement and Knowledge Sharing
Throughout his modification journey, Kevin remained an active participant in online forums and social media groups dedicated to the Explorer ST. He generously shared insights, experiences, and technical knowledge, fostering a collaborative environment that empowered other enthusiasts to embark on their own modification endeavors. This communal exchange of information contributed significantly to the growing interest and development within the Explorer ST enthusiast community.
Conclusion
Kevin Krupski’s transformation of his 2020 Ford Explorer ST from a standard family SUV into a 657 WHP supercar challenger epitomizes the spirit of automotive enthusiasm and innovation. His journey underscores the potential that lies within unconventional platforms and serves as an inspiring testament to the rewards of perseverance, creativity, and community engagement in the pursuit of automotive excellence. As the Explorer ST continues to gain recognition in the performance realm, Kevin’s build stands as a beacon, illuminating the boundless possibilities that await those daring enough to reimagine the capabilities of their vehicles.
