CAMSHAFT PROFILE:

292°/280° | 10.40mm/10.60mm

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.

    The 358-B has had many independent tests completed by various engine builders check out the latest cam swap dyno test.
