The pumps sell for about $1,000 compared to our closest competitors at about $550, but we spend a lot more money making each part in the pump. Kinsler states its pump will live at a higher pressure than others it has tested; 200 psi for sprint car use, and 300 psi or more for drag racing. At 5 lb/hr, the Micro Motion is off just .005-pound. The essential element for surviving an accident is removing kinetic energy from the driver's body slowly. With perfectly calibrated refueling and safety procedures in place, drivers do not need to waste time turning their engines off and back on again. Kinsler continued, Some electric fuel pumps are extremely well made, and a few brands offer variable output flow controlled by the ECU, which can be very handy to obtain an exact fuel map. The engines in today's NASCAR race cars produce around 750 (and sometimes, more than 800) horsepower. endstream endobj startxref Location of fuel storage tanks and their capacities. The latest pumps have a seal design that cant leak externally and have one of the side plates loaded by outlet pressure against the side of the gears to cut the internal leakage to a minimum, which gives improved pump performance. With reduced power, the goal of designing a car for the super-speedway tracks is to minimize drag. To prevent this, NASCAR officials developed a set of flaps that are recessed into pockets on the roof of the vehicle. Do NASCAR Cars Need To Be The Same Shape?
