The horsepower of a Detroit Diesel 6-71 engine varies depending on its specific configuration, including whether it is naturally aspirated, turbocharged, or twin-turbocharged. A standard, naturally aspirated 6-71 Detroit engine typically produces between 170 and 228 horsepower.
The Detroit Diesel Series 71 engines are renowned for their durability and distinctive two-stroke operation. The "6-71" designation indicates an engine with 6 cylinders, each with a displacement of 71 cubic inches. This engine series was widely used in various applications, including marine, industrial, and heavy-duty truck sectors, leading to multiple power output variations over its production span.
Horsepower Variants of the Detroit Diesel 6-71
To provide a precise answer, it's essential to consider the different configurations of the 6-71 model. The table below outlines the common horsepower ratings for various 6-71 variants:
| Model | Configuration | Horsepower (HP) | Power (kW) | RPM |
|---|---|---|---|---|
| 6-71 | Naturally Aspirated | 170–228 | 127–170 | 2100 |
| 6-71T | Turbocharged | 275–285 | 205–213 | 2100 |
| 6-71TT | Twin-Turbocharged | 230 | 172 | 1950 |
| 6V-71 | V-Configured (6-cyl) | 228 | 170 | 2100 |
- Naturally Aspirated (6-71): This is the base model, delivering power suitable for a wide range of applications where forced induction wasn't required.
- Turbocharged (6-71T): The addition of a turbocharger significantly boosts the engine's power output, making it suitable for more demanding tasks.
- Twin-Turbocharged (6-71TT): This configuration further enhances performance, offering a different power curve for specific operational needs.
- V-Configuration (6V-71): While not a straight-six like the others, the 6V-71 is part of the same Series 71 family and shares similar cylinder displacement characteristics, offering comparable power to the naturally aspirated inline version.
Understanding these variations is crucial, as the term "671 Detroit" can refer to any of these engines, each with distinct performance capabilities. The specific horsepower of any given 6-71 engine depends on its original factory configuration and any subsequent modifications.
