With Porsche ending its factory support of its ALMS program at the conclusion of the 2008 ALMS season, the Dyson team was fortunate to strike up a partnership with Mazda to campaign two BP / Castrol-sponsored Lola B09/86 LMP2 cars for the 2009 season. This move rekindled the team's long standing relationship with Lola and Advanced Engine Research, who was responsible for the Mazda LMP2 MZR-R powerplant. The team claimed two class victories at Lime Rock Park and at the season ending Petit Le Mans race. The team ended the season 2nd in the team championship behind their main rivals, Fernandez Racing. Drivers Butch Leitzinger and Marino Franchitti finished 2nd in the drivers championship, while Chris Dyson and Guy Smith finished fourth.
