The new BTR Turbo Stage 4 V2 cam was designed for use in serious effort stock stroke applications spinning over 8000rpm with supporting valvetrain components. For you folks who may have a ~408" bottom end spinning it in the 6400-6800rpm range, this new cam will also be a very good fit.  Developed in house, we went back to the drawing board in search of more power and torque ,even with the use of less intake duration. These new BTR lobe designs were Spintron tested to help achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards.

Paired to an S400 frame (or similar size), this camshaft will help you move some serious air. Regarded as the BIG STICK of our turbo cam lineup, the Stage 4 is here to knock it out of the park.
