 In 1952, Fred Agabashian in a Cummins diesel won the pole at the Indianapolis 500 race with a turbocharged 6.6-liter diesel car, setting a record for pole position lap speed, .Don Cummins and his chief engineer Neve Reiners recognized that the low center of gravity of the flat engine configuration (designed to lie beneath the floor of a bus) plus the power advantage gained by the novel use of Elliott turbocharging would be a winning combination.At the start, a slow pace lap (reportedly less than ) apparently induced what is now referred to as "turbo lag" and badly hampered the throttle response of the Cummins Diesel.
