Darrell Cox started in 1995, SpeedNeeds, through passion of performance applying big horsepower to small cubic inch engines starting with carburetors and nitrous. Past mentor, Mark Riley from Turbo Tune, stirred the passion for turbocharging the Green Goblin (95 Dodge Neon). Media coverage in the Sport Compact magazines, launched the interest of Mopar to sponsor Darrell Cox in 2003. In 2003, SpeedNeeds was renamed to Darrell Cox Racing from much encouragement by Shaun Carlson. This same year, Darrell teamed with Jorgen Moller in building the engine and intake manifold for the Bonneville Salt Flats record. In 2003-04 Darrell built and was crew chief for driver, Mike Crawford in the Hot Rod class and Scott Mohler in the All Motor class for NHRA Sport Compact series. In 2004-06, long time driver Mike Crawford finished the Mopar, Dodge and SRT sponsorship for Darrell Cox Racing, setting the all time record for the Dodge SRT-4 of 7.90 e.t at 188mph in the 1/4-mph. Darrell Cox Racing in 2010 became a division of Cox Performance Inc. to promote further lines of products for other platforms than the SRT-4 Neon. We're a company that wears their heart on their sleeve. Many customers have become close friends and family just like at the track.
