The Si-Trim and SCi-Trim are now the standard superchargers included in most Vortech street-legal supercharging systems. Both new superchargers are equipped with the high-performance Si-Trim compressor, allowing for greater airflow, boost pressure and power gain potential.

The product of Vortech's latest research and development, the Si-Trim is capable of performing at a peak efficiency of 78% - a marked improvement over the S-Trim's class-leading 72%. Because a more efficient supercharger takes less power away from an engine and generates less heat, the overall horsepower gain on any vehicle will be greater with an Si-Trim vs the S-Trim.

One of the key objectives in developing the Si-Trim was extending the performance range of the supercharger. Due to its increased efficiency 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 drastic improvement in performance.
