Our Program

Turn 3 Motorsport is a full-service operation specializing in racecar preparation, engineering, and driver development. Founded and managed by racecar driver and coach Peter Dempsey, T3M is focused on professional service, team member growth, and high-level performance across multiple racing 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).
