Dyson Racing raced a partial late season schedule in the American Le Mans Series in 2002 with the Lola EX257-MG. (Lola factory type number B0160). They raced the Lola in the LMP2 class in 2002, one step removed from the top LMP1 class, in preparation for a full season assault on the P2 championship in 2003. with four class wins, including the 12 Hours of Sebring and three additional podiums, Chris Dyson won the P2 championship. Dyson Racing also made racing history at California's Infineon Raceway in July, when James Weaver and Butch Leitzinger scored the first overall race win in ALMS history for a car in the P2 class. It was also a one, two class finish for the team.

Increasing the horsepower and weight, the team moved their two Lola EX257s up to the LMP1 class for 2004. James Weaver and Butch Leitzinger placed second in the championship with a win at Mosport and seven podium finishes in nine races.

In 2005, Dyson Racing won at Mid-Ohio, placing one-two, the first one-two for the team in ALMS and also won at Mosport. Both wins were with the #16 car with Butch Leitzinger and James Weaver. Mosport was Weaver's 100th career race win. Chris Dyson consistent competitiveness garnered him second place in the championship with six seconds and third in ten races.

2006 saw a change in their equipment as they contested the ALMS LMP1 championship with a pair of Lola's new B06/10's with AER's V8 Turbo. After some new car development vagaries in the beginning of the season, the last half of the season proved fruitful and at the end of the year, James Weaver finished second in the championship and Butch Letizinger was third. The team garnered eight race and class podiums, three poles and two fastest race laps. For 2007, the team renewed their historical relationship with Porsche and ran two of their LMP2 RS Spyders in the most competitive class in the ALMS. Butch Leitzinger and Andy Wallace finished third in the LMP2 championship, four points ahead of Chris Dyson and Guy Smith's fourth place. For 2008, the team continued with their Porsche RS Spyders, starting off the season with a second and third at the 12 Hours of Sebring. At year's end, the team finished third in the team championship and Marino Franchitti and Butch Leitzinger were fifth in the drivers standings followed by Chris Dyson and Guy Smith in sixth place.

Rob Dyson: "The Riley and Scotts were starting to reach their limits. The MG Lola prototype was the only real opposition to the wining Audis in the 2002 24 Hours of Le Mans and the 675 class looked pretty interesting in the ALMS, so we went to the Lola and won the championship in our first full year of competition.

"The Lola was a different animal than the Riley and Scott. The Lola was a very light car, all carbon fiber chassis. The aero loading was more, and there were a number of other learning areas we had to master with the Lola.

"We spent a week in the wind tunnel and that created a whole lot of things for us that made the car run better. We had to get the aero down, we were not doing a good job in that area. We got a handle on the engine and the drive train and we got the suspension stiffened up and we got that all straightened out. We ran the four cylinder AER engine which put out a goodly amount of horsepower. Our switch to Michelin tires made us even more competitive. And we were able to take the fight to the Audis at every track.

"You know, the team is always evolving. 2007 saw us back with Porsche. We ran Porsche 962's in IMSA GTP from 1985 through 1991, winning a dozen races. Understanding the techniques behind any race car is a challenge. The guys have done a great job of unlocking its secrets. We have had good support from Porsche and that has helped a lot.

"When I look back, I never thought I would reach this level. I thought I would run a little bit and see what it was like out there, see what it was like to be a race car driver. I did not have any goal in mind to win the Indy 500 or Le Mans, or the Daytona 24 Hours or anything like that. I won the first race I ever ran, a Watkins Glen Regional and I won the race over all and beat everybody. I kept on doing it with no real end game or objectives, I just enjoyed it so much.

"It is unlike any other sport because it has all the composite things that you want in a competition: it has the logistics, the team effort, camaraderie, lots of competition, hard work, speed, etc. We take our racing seriously. We are not here just to participate. We have never shown up at a race just to show up. We show up to win the race. We have always wanted to compete, at the highest levels, no matter where we were. And that has remained the same throughout all of our racing history."
