PULSAR Billet S488 Turbo with 96mm Turbine wheel

Turbo selection depends on engine size, boost target, rpm range and desired response. A smaller turbo spools faster; a larger turbo supports more top-end power.

Poor placement or sizing can cause boost creep or unstable boost control.

The Pulsar Billet S488 Turbo is designed to support power levels between 750 to 1400 horsepower. Its high compressor flow rating of 120 lb/min makes it suitable for high-performance applications, including drag racing and circuit racing, where maximum power output is required.

The T6 turbine housing is available in 1.32 A/R or 1.58 A/R with a 5.75" Marmon outlet, while the T4 option comes in a 1.25 A/R configuration with a 4" V-band outlet. The choice between them will depend on your engine setup and desired boost characteristics, with T6 generally supporting higher flow applications.

The Pulsar S488 Turbo requires a 1/4" NPT oil feed and a standard T6 drain flange for oil drainage. Ensure that your oil supply is adequate to maintain proper lubrication, especially under high-performance conditions.

When installing the S488 Turbo, ensure that the compressor inlet and outlet match your existing piping and that the turbine housing is compatible with your exhaust manifold. You may need to modify or fabricate custom piping to achieve optimal fitment. Always check for adequate clearance and alignment to prevent boost leaks and ensure proper operation.

The 7+7 blade billet compressor wheel with extended tip technology enhances aerodynamics, resulting in improved efficiency and reduced turbo lag. This design allows for better airflow and performance at higher boost levels, making it ideal for serious performance builds.
