While this is our entry level head unit, it is also the most efficient head unit for stock engines in the 500 – 600 RWHP range. The Si is also the only head unit that can be used in our CARB compliant kits.
Standard Features:
The V-2 (ENGINE OILED) and V-3 (SELF-CONTAINED) models, with their highly advanced computer designed gears feature an optimized helical profile which allows for quieter operation while providing superior performance. All V-2 SQ units feature a 3.6:1 internal step-up ratio and are direct bolt-on replacements for our HD V-1 units. The supercharger uses the quieter helical cut gears (3.61:1 ratio). The V2 and V3 Si Supercharger is capable of up to 775HP on modified vehicles. Extraordinary 78% peak efficiency. Ideal for latest generation of improved breathing, high-power street and strip engines.
The new improved Si impeller design provides increased flow and efficiency over earlier designs.
We also have a great “Trade In” program that you should take advantage of when looking to step up to a bigger head unit.
