Description

The SpeedFactory Racing SF-04-005 is a ram horn turbo manifold engineered for high-power applications demanding significant torque and rapid spool alongside substantial top-end horsepower, making it ideal for drag racing vehicles. Constructed from premium 1.5” Schedule 40 stainless steel, this manifold features an equal-length design that promotes quick spooling of larger turbos and generates broad powerbands that extend to the upper RPM range. The TIG-welded construction, complete with back purging, ensures exceptional quality and durability. Its cylinder head, wastegate, and turbine inlet flanges are precision CNC machined from ½” plate 1018 steel, with all mating surfaces machined flat for a perfect seal. This turbo manifold is compatible with D Series, B Series, and H Series engines. It is available with various wastegate flange options, including T3 (38-40mm 2-bolt and V-band, 44/46mm V-band) and T4 (open, single 44mm/46mm, and open 38-40mm 2-bolt).
