Dean Perkins, a former Kiwi touring car champion, made headlines with his 383-cube Roush Yates D3 NASCAR engine fitted into his beloved XD Falcon. The engine, despite its unassuming appearance, boasts impressive specs, delivering 850hp at 9000rpm and 550lb-ft at around 7400rpm. What sets this powerhouse apart is its simplicity – no superchargers, no turbos, no nitrous. Just raw, naturally aspirated power.
This particular engine, sourced from Roush Yates in North Carolina, found its home in Perkins’ XD Falcon for the Central Muscle Cars series in New Zealand. Perkins’ decision to opt for the D3 flat-tappet NASCAR engine proved to be a winning one, clinching victories in the series two years in a row. The engine’s success lies in its design – based on the Windsor but with a unique nine-inch deck height, offering versatility and performance unmatched by production engines.
The Roush Yates D3 engine features evolved Cleveland heads that flow 390cfm, coupled with Jesel rockers and solid lifters reminiscent of 50s technology. Despite its old-school components, the engine incorporates modern features like rollerised cam bearings and advanced oil control mechanisms to sustain high revs and power output. With a compression ratio of 12:1 and running on a 98-octane ethanol blend, the engine is optimized for high performance.
Oil control is a critical aspect of the Roush Yates D3 NASCAR engine, with meticulous sealing to prevent oil starvation at its 9000rpm redline. Perkins, not content with the engine’s current configuration, plans to upgrade to a 410-cube setup for future endeavors, including a venture to Bathurst. This expansion showcases the engine’s adaptability and performance potential, proving its worth on the racing circuit.
Scott Taylor, the journalist behind this feature, sheds light on the technical intricacies of Perkins’ NASCAR engine, emphasizing its design, power delivery, and future prospects. The narrative captures the essence of Perkins’ racing journey, marked by innovation, performance, and a relentless pursuit of excellence.
As the automotive world evolves, engines like the Roush Yates D3 continue to embody a blend of tradition and innovation, pushing boundaries and setting new standards in racing performance. Perkins’ story serves as a testament to the enduring legacy of NASCAR engines and their impact on motorsports, inspiring enthusiasts and professionals alike to strive for greatness in every lap.
