Si-Trim Impeller

The Vortech Si-Trim Supercharger is now included in our Corvette street-legal supercharging systems as standard equipment. This new supercharger is equipped with enhanced high-performance compressor stages, allowing for greater airflow, boost pressure and power gain potential.

These new compressors are a product of Vortech’s latest research and development process. The Si-Trim is capable of operating at a peak efficiency of 78% – an impressive 6% improvement over the S-Trim’s already class-leading performance. Not only does a more efficient supercharger produce a cooler air charge, it also allows for reduced engine load which results in greater net horsepower and torque gains.

One of the key objectives in developing the Si-Trim was extending the useful performance range of the supercharger. Due to its increased efficiency and flow at higher performance levels, the Si-Trim can support applications which demand more airflow and pressure than what was considered practical with the S-Trim – particularly vehicles with modified engines. Customers with these more demanding applications will experience a more dramatic improvement in performance.
