VF-Engineering chose to build this kit with the most efficient Vortech unit available ? the V3 Si trim. Its super quiet helical cut gears make it super stealthy yet still remind onlookers that there is something different under the hood. The Si trim supercharger delivers a bigger mid range punch than the race ?T-trim? yet is capable of supporting over 700hp. The centrifugal supercharger compressor maps ideally match the 8300 rpm revving S65 BMW Motorsport engine.
