The KraftWerks Rotrex-based supercharger kit for 2013–2017 Scion FR-S features a 30mm C38 unit and includes tuning to unlock broad, usable power gains across the rev range. The proprietary traction-drive Rotrex design delivers compact, quiet operation with efficient transient response compared with other forced-induction systems. This kit is engineered for street and track use to produce significant power increases (noted up to high gains on some applications) while emphasizing drivability, packaging and engineered testing by KraftWerks.
