• Gen.2 Supports Rotrex C30 (if buying the kit together with the SC, then it will be automatically included, if buying later kindly email us or request it.  (Gen.2 Available from Fall 2026)
• Depending on the Supercharger unit and pulley used, it may see boost higher than 14PSI with an air to air intercooler, For most stock engines we suggest going with a larger Supercharger pulley to keep the boost under 10PSI for engine longevity.
• To use the full potential of the larger Superchargers, the engine must be built to hold high boost, the stock engine should not be pushed beyond 10PSI.*
