MBE 4000 SERVICE MANUAL Table 17-1 Factors Affecting Wheel Horsepower All information subject to change without notice. (Rev. 2007) 6SE412 0702 Copyright © 2007 DETROIT DIESEL CORPORATION From Bulletin 1–MBE 4000–07 17-5 Factors Considerations Winter-front Installation Improper installation or usage of a winter-front will result in extremely high intake air temperatures and reduced mass flow of air into the combustion chamber. Vehicle Application Unusual applications such as triple drive axles, PTO's, pumps, high air compressor duty cycle, etc., will have higher parasitic loses resulting in less horsepower at the wheels. Foot Pedal Make sure the foot pedal has complete travel.
The foot pedal position can be monitored on DDDL (accelerator pedal pos.)
