only work as a single-point system. In the approved system, two hoses coming from the storage tank combined at the fueling mechanism handled by the fueler. The crew member previously responsible for the operation of the vent and jack was now free to operate only the jack. Cars raced on all ovals in the same configuration introduced at the 88th Indianapolis 500 in May 2004 with minimal aerodynamic changes. The changes were limited to specified areas of the underwing and sidepods. The IRL required teams to use the same engine cover as last year without modification. Teams were allowed to change engines prior to qualifying without penalty at the following events, which were scheduled to be three-day events: Homestead, St. Petersburg, Motegi, Texas, Milwaukee, Infineon, Watkins Glen and California. The amount of methanol teams may have in their trackside tanks was changed. Teams were allowed to carry 85 gallons for 187.5-mile races, 90 gallons for 200-mile events, 100 gallons for 225-mile events, 125 gallons for 260-mile races, 135 gallons for 300-mile events, 175 gallons for 400-mile events and 225 gallons for 500-mile events. The mandatory minimum weight of cars was 1,600 pounds, 75 pounds heavier than the oval minimum weight. The additional weight was attributed to the brake system, which consisted of an aluminum brake caliper, steel rotor and pad as specified by the IRL, as well as the limited slip differential in the gearbox.
