Stage 2 racing cams for professionally built BMW S58 engines that can deliver 800hp to 1400hp with 66-75mm turbo sizing and aftermarket intake plenums.
- The cams enable full use of Valvetronic and Dual VANOS while allowing you to lock Valvetronic when using an aftermarket throttle body. (Please check valve-to-piston clearances on full travel of VANOS and Valvetronic).
- Upgrade valve springs with Kelford Cams’ KVS58-BT.
- Ensure the clearance of the new racing cam lobe with the intake intermediate rockers and trim or deburr OEM pressed steel rockers if necessary.
