The Skunk Ultra BMF TLRC Camshaft System for B-Series engines is a roller valvetrain and camshaft combination that represents the latest evolution in B-Series Valvetrain and Camshaft design, and IS the ‘missing link’ required to achieve levels of engine efficiency and performance never before possible. At the core of the system are lightweight steel roller rockers and billet steel camshafts with CNC-precision-ground advanced lobe profiles. Skunk2 Ultra BMF roller camshaft profiles open and close the valves much quicker than what is possible with an OE sliding style valvetrain, which is key to improving power and efficiency. Additionally, the Skunk2 Ultra BMF TLRC was designed to be stable at 12,000rpm.  A stable, high RPM-capable valvetrain combined with improved efficiency opens up a new realm of performance not previously possible.

The Skunk2 Ultra BMF TLRC System is a requirement for any serious B-Series engine builder or racer looking to compete at the next level and can be used on both forced induction and naturally aspirated engines.

Results will obviously vary from set-up to set-up, but the real-world feedback we commonly receive includes: increases of +100hp, a broader power band that carries higher, a dramatically improved VE table, +5mph at the 1/8th track, the ability to utilize larger exhaust housings and turbines. Racers who currently use the Skunk2 Ultra BMF TLRC System have all been completely shocked by the massive gains in engine efficiency and vehicle performance.
