The in-tank fuel pump accommodates variable pressures, half-inch fuel lines, and eight injectors, each capable of delivering a flow rate of 600cc/min – enough to drain the fuel tank in around 13 minutes at full power.
The large-nosed crank drives a high-flow gerotor oil pump that feeds a lubrication circuit servicing eight high-flow piston cooling jets. A high-capacity oil/air heat exchanger, mounted in the front of the car, mitigates oil temperatures when driving conditions are harshest. The 0W-40 synthetic oil was developed for SRT by Pennzoil.
Additional cooling measures include a low-temperature circuit with two air/coolant heat exchangers integrated into the supercharger housing. This setup is designed to keep air temperatures below 140° Fahrenheit (60° Celsius) under extreme ambient conditions, while enabling air flow of up to 30,000 liters per minute. It is effective enough that engine power will not be de-rated due to cooling demands, even after 20 laps of a grueling 3.1-mile road course at an ambient temperature of 100° Fahrenheit.
