ProCharger CS-1 Self-Contained Centrifugal Supercharger Head Unit - 550 HP - 900 CFM - 24 PSI Max Boost - Black Finish - PC061A-xxx-B
The ProCharger CS-1 Self-Contained Centrifugal Supercharger Head Unit offers a unique blend of compact packaging, high impeller speed, and the proven reliability ProCharger is known for. Designed for naturally aspirated engines producing approximately 125-250 horsepower, the CS-1 supports up to 550 supercharged horsepower while delivering up to 900 CFM of airflow.
Capable of producing as much as 24 PSI of boost, the CS-1 delivers serious forced induction performance from a compact 7-inch volute. Its 3.5-inch inlet, 2.75-inch inducer, 4.25-inch exducer, and 2.5-inch outlet hose connection provide the airflow needed for high-performance street, strip, marine, powersports, and custom supercharger applications.
The CS-1 features ProCharger's proven self-contained oiling system, eliminating the need to connect the head unit to the engine's lubrication system. This simplifies installation, minimizes external plumbing, and makes routine maintenance easier. Reverse-rotation capability also provides added flexibility when designing custom mounting brackets and drive-system layouts.
High Impeller Speed in a Compact C-Series Package
One of the CS-1's defining characteristics is its 8.30:1 internal step-up ratio. Combined with a maximum impeller speed of 105,000 RPM, this distinguishes the CS-1 from other head units sharing the PC061A-xxx base part number. It gives builders a dedicated C-series option configured around a different operating profile while retaining the compact footprint and self-contained architecture of the broader family.
The CS-1 is an excellent option for builders who need more airflow and boost capability than smaller compact head units can provide, but whose engine combination does not require the higher published horsepower capacity of the C-1, C-1R, or C-1X. Its 550 HP rating and 900 CFM airflow capacity allow the compressor to better match the needs of the engine without stepping into a larger head unit than necessary.
Understanding the PC061A-xxx Family
The PC061A-xxx manufacturer part number is shared by multiple ProCharger C-series head units. It identifies a family of compact, self-contained superchargers rather than a single compressor configuration. Models within this family share the same core packaging, but their published horsepower ratings, airflow capacities, maximum impeller speeds, internal step-up ratios, and intended applications vary.
The CS-1 version of the PC061A-xxx family is distinguished by its published 550 HP capacity, 900 CFM airflow rating, 105,000 RPM maximum impeller speed, and 8.30:1 internal step-up ratio. Compared with the C-1 configurations sharing the same base part number, the CS-1 carries lower published horsepower and airflow ratings while featuring a significantly higher step-up ratio and maximum impeller speed. Those published differences make selecting the correct model especially important.
Built for Efficient, Dependable Performance
The CS-1 combines compact dimensions with smooth centrifugal boost that increases with engine RPM. This progressive boost curve delivers predictable throttle response and strong upper-RPM performance when the head unit is properly matched, installed, and tuned for the engine combination.

Frequently Asked Questions
How does the CS-1 differ from other PC061A-xxx head units?
The CS-1 shares the PC061A-xxx base part number with several C-series models, but its published specifications are different. It is rated for 550 HP and 900 CFM and uses an 8.30:1 step-up ratio with a maximum impeller speed of 105,000 RPM. Those figures distinguish it from the C-1-based configurations that carry higher horsepower and airflow ratings but lower published step-up ratios and impeller-speed limits.
Does the ProCharger CS-1 require engine oil lines?
No. The CS-1 uses a self-contained oiling system with a published oil capacity of 3.2 ounces, eliminating the need for engine oil feed and return lines. Follow ProCharger's lubrication, mounting orientation, service, and maintenance requirements.
Why Buy from Beefcake Racing?
When multiple ProCharger head units share the same manufacturer part number, choosing the correct model requires more than comparing the base SKU. Beefcake Racing can help you evaluate the published airflow, horsepower range, impeller speed, step-up ratio, packaging, and intended use of each PC061A-xxx configuration so you can select the head unit that properly matches your build.
