Since the rules for Super Unlimited Class do not specify engine location, the Sidewinder D-MAX Type-R crew was free to locate the Duramax 6.6L turbodiesel for optimum weight balance in the chassis. Electronic weight scales were placed at the wheel positions under the chassis. Next, appropriate weights were placed inside the chassis to represent heavy components such as the fuel cell, batteries, radiator, intercoolers, etc. The driver was also seated in position. With that done, the engine and transmission combination was moved around until a 50/50 weight balance, side-to-side and front-to-rear, was attained. This weight balance produces the best handling and traction for racing. Relevant to the front wheel location, the Duramax is set back approximately 18 inches as compared to a stock pickup, and one inch to the right of the centerline of the vehicle. The chassis is configured to accept the placement of the turbodiesel engine in the new location.

In racing trim, the Sidewinder D-Max Type-R chassis runs very close to the track. The engine also sits very close to the ground. Banks’ billet aluminum dry sump oil pan allows the engine to be placed very low in the chassis. Banks Crew Chief, Sheldon Tackett, estimates the engine in the Type-R to sit nearly 16” closer to the ground than it does in a stock production pickup.
