K Series Sidewinder Turbo Manifold

The K-Series Sidewinder Turbo Manifold from SpeedFactory Racing was designed for quick spooling of medium to large-sized turbos, creating broad powerbands that are sustained to the top of the RPM range. Suitable for drag and road race vehicles, this manifold requires large torque and great spool with strong top end horsepower. It's constructed from premium 1.5” Schedule 40 stainless steel, and the TIG-welded, back purged design offers unbeatable quality. Our cylinder head, wastegate, and turbine inlet flanges are CNC machined from ½” plate 1018 steel and all mating surfaces are flat.
