Product Description
BorgWarner 179191 S500SX (S591/110/.85) is a big-frame AirWerks charger built for four-digit power. The 91mm inducer, 120.2mm comp wheel O.D., and 110mm turbine pair with a .85 A/R, divided T6 housing to deliver serious flow for high-fuel street/strip, sled pull, and drag builds. Extended-tip aero, journal bearings, and adjustable cover orientation make it a proven, durable choice when you need massive airflow with reliable spool.
Fitment / Use
- Universal performance turbocharger for custom applications. Commonly used as a high-power single or low-pressure (atmospheric) unit in compound setups on Cummins, Power Stroke, and Duramax builds. Requires T6 manifold and matching downpipe.
- Adjustable compressor/turbine cover orientation; standard BW inlets/outlets ease fabrication.

FAQs
Is 179191 a direct bolt-on?
No. This is a universal AirWerks unit for custom builds. It requires a T6 divided manifold, matching downpipe, oil feed/return, and custom charge piping/fab work.
How much power can it support?
Typical S500SX 91mm builds target roughly 900–1500+ HP with proper fueling, air, and engine setup. Actual results vary by displacement, fuel, ambient conditions, and tuning. (See the S500SX data sheet for compressor dimensions and flow context.)
Good as a big single or only for compounds?
It can be run either way. As a single, expect later spool; many users run it as the atmospheric (low-pressure) charger in a compound setup for strong top-end flow and EGT control.
CARB / emissions status?
Not CARB approved; commonly listed as Emissions Code 2 (not legal for sale or use in California on pollution-controlled vehicles).
