Our Program

Turn 3 Motorsport is a motorsports competition team specializing in race car preparation, engineering, and driver development and currently competing in the USF Pro Championships Presented by Cooper Tires. Founded and managed by race car driver and coach Peter Dempsey, T3M is focused on professional service, team member growth, and high level performance across multiple racing series including the USF Pro 2000 and USF2000 series.
 
In 2019, the team secured the Blue Marble Cocktails Radical Cup North America championship titles in the 1340cc, 1500cc, and overall classes. Later that year, Peter and Turn 3 Motorsport achieved a record-breaking win at the NASA 25 Hours of Thunderhill endurance race, piloting the #10 Eastern Racing / Turn 3 Motorsport Radical SR3 RSX 1340 to a dominating win, leading 638 out of 672 laps, and becoming the first car under two liters to achieve the overall win.
 
In the team’s rookie season, Turn 3 Motorsport attracted attention out of the gate by winning the season opener of the 2020 Indy Pro 2000 Championship Presented by Cooper Tires in a sweeping performance with Singaporean driver Danial Frost. Frost and the team went on to achieve a pole position, six podium finishes, and third overall in the championship in 2020.
 
In 2021, T3M expanded its presence in the Road to Indy by introducing a two-car program into the Cooper Tires USF2000 Championship alongside its Indy Pro 2000 Championship campaign. In its debut USF2000 season, the team found victory at the season finale with American driver Josh Green as well as earning an additional podium and fifth overall in the championship. The team earned further accolades in the Indy Pro 2000 series with a race win at the season finale by Irish driver James Roe as well as a pole position at World Wide Technology Raceway and seventh overall in the championship.

In 2022, T3M showed its strength and teamwork by achieving a podium, win, and/or pole at 7 of the 9 events on the Road to Indy calendar with drivers Josh Green, Jonathan Browne, and Christian Weir each earning the aforementioned results across two different series (USF2000 and Indy Pro 2000).

In 2023, T3M tied for the most amount of wins in the USF Pro 2000 season with drivers Michael d’Orlando and Christian Brooks earning a total of five wins for the team. The team also earned seven pole positions, the most of any other team, and finished second overall in the Team Championship.

  • Peter Dempsey
    Peter Dempsey is an Irish race car driver, engineer and driver development leader with a lifetime of motorsport experience. ​ Peter began his career racing go-karts in Ireland at age 8. In 2004, he began racing competitively in the Formula Ford Series in Ireland and the UK as a driver for his father's racing team, Cliff Dempsey Racing. In 2005, he entered into his first full season of competitive racing in the Formula Ford Series where he won 33 out of the 43 races that he competed in. That same year, Peter was awarded the Motorsport Ireland Young Racing Driver of the Year Award. From 2006-2007, Peter continued to win numerous races and awards including third overall in the Formula Ford championship in 2006, two more nominations for the Motorsport Ireland Young Racing Driver of the Year Award, and the prestigious Walter Hayes Trophy both years in a row. In 2008, Peter boldly decided to move his racing career to the U.S.A. where he saw a major opportunity in the open-wheel development ladder. He completed his first season in the Star Mazda Championship with four wins, seven podiums, and third overall in the driver's championship. He entered the series once again in 2009 winning five races, six podiums, and finishing second in the driver's championship after a devastating DNF in the final event. In 2010, Peter broadened his racing resume further by racing an LMP2 car in the world famous 10-hour Petit Le Mans event at the Road Atlanta road course. He also made a trip back home to compete in both the Formula Ford Festival and the Walter Hayes Trophy which he won for the third time, becoming only the second driver to ever do so. From 2011-2013, Peter competed in the Firestone Indy Lights Series where he accomplished eight podium finishes and a record-breaking win that ended in a four-wide finish with a .0026-second margin of victory, going down in history as one of the most exciting finishes in the history of the Indianapolis Motor Speedway. ​ In addition to his own racing resume, Peter has enjoyed mentoring and coaching many drivers to reach their full potential as they climb the motorsports ladder. It was this gratification along with his extensive racing experience that led Peter to form Turn 3 Motorsport.
