FAQ
How much horsepower can the BorgWarner 179191 support?
The BorgWarner 179191 S500SX is commonly used in applications targeting approximately 900 to 1575 horsepower when paired with proper fueling, airflow, engine modifications, and tuning.
Is the 179191 a good compound turbocharger?
Yes. The 179191 is frequently used as the atmospheric (low-pressure) turbocharger in compound turbo systems due to its exceptional airflow capability and high horsepower potential.
Can this turbo be used as a single turbocharger?
Yes. Many high-horsepower competition diesel engines use the S591 as a standalone turbocharger, although spool-up characteristics typically make it best suited for dedicated performance applications.
Does the BorgWarner 179191 use ball bearings?
No. This turbocharger utilizes BorgWarner's proven twin hydrodynamic journal bearing system for durability and reliability under extreme operating conditions.
Does this turbo require a T6 manifold?
Yes. The 179191 is designed around a divided T6 turbine housing and requires a compatible T6 exhaust manifold and supporting hardware.
What supporting modifications are recommended?
Supporting modifications typically include upgraded injectors, high-flow fuel systems, custom tuning, reinforced engine components, intercooler upgrades, charge piping, exhaust modifications, and proper boost and EGT monitoring.
