It was 104 degrees when Team Jefferies started their engine. “The temperatures inside the truck engine compartment and drivers cockpit were insane,” said Damen Jefferies. “My right foot got burned and my toes got blistered through my Nomex racing shoes.”

In the first lap, Team Jefferies had one flat tire. The team was also concerned about temperatures under the hood of the trophy truck and stopped at the main pit to try and cool it down.

“We are still learning this truck,” said Jefferies. “The engine can lose power if it runs for long periods of time in this kind of heat. We also wanted to take the time to ensure we weren’t causing any damage to the vehicle and use this opportunity to solve any problems that could pop up at a future race in this kind of heat.”

One of the constants Team Jefferies can rely on are K&N products. The No. 22 K&N Trophy Truck is equipped with a K&N designed air induction system and a K&N performance oil filter. This provides Team Jefferies with the power and protection it needs for racing in extreme conditions. “Our K&N filter is amazing,” said Jefferies. “It stops 100 percent of the dirt and silt from damaging the engine. We can’t even see where we are going through the dust and it manages to filter out the dust and debris while making horsepower. K&N filters continue to attest that they can withstand any environment.”

The second and third lap went well for Team Jefferies. They passed several other trucks that were on the side of the track due to mechanical problems from the heat. “We had the pit crew change the MAP and cam sensors before we went out on our last lap,” said Casey Jefferies, co-rider and lead mechanic of the No. 22 K&N Filters Trophy Truck. “We wanted to make sure we were not missing anything.”

The truck went out for its last lap and ran well for a while. “We started to lose power again at the top of the wash at mile 222,” said Jefferies. “We stopped on the side of the course for about three minutes to let everything cool off. Once we got going again we had full power to the finish line.”

Team Jefferies was happy with its 12th place finish. “We are very happy with this result, the vehicle is new and has a one of a kind transmission that had never raced,” said Jefferies. “The Primm 300 was a huge step in the right direction. We will do more testing and get the truck ready for the Baja 1000.

The next race for the No.22 K&N Trophy Truck will be the 4th annual M.O.R.E. (Mojave Off-Road Enthusiast) Powder Puff Race for the cure. Proceeds and donations from the event will benefit the Cedars Sinai Cancer Research Center for women. Mindy Jefferies will drive and Jenna Jefferies will co-ride.

From there, Damen and Casey Jefferies will race at the SCORE Baja 1000 on November 19th through 22nd on Mexico’s Baja California Peninsula.
