Summit Racing™ Pro LS Turbo Camshafts
Summit Racing™ Pro LS Turbo cams are affordable and specifically designed to optimize cam timing with turbochargers. The lobes are stable up to 7,000-plus rpm with the exhaust lobes opening softly against high cylinder pressure for reduced stress on the valvetrain. Overlap has also been reduced in order to prevent reversion, which is typically seen with higher turbine inlet pressures. They come in distinct stages that give you the idle, spool, and power characteristics that match your engine and turbocharger. Starting with American bearing steel, they are precision machined on a Landis 3LB CNC grinder with CBN diamond wheels for unmatched quality. The lobes have been designed for stability at high rpm with the spring pressures found in commonly available quality spring packs.
