    Info
    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.

    Stage 1
    217/22X .616"/.616" 113 LSA
    Good for 5.3s and 6.0s with cathedral port heads and factory or aftermarket long runner intakes, it also gives great results in LS3 headed applications as well. At the end of the day, if you're hanging a smaller 62-75mm turbo on your LS-based build ,and plan on putting some street miles on it, the Turbo Stage 1 is hard to beat.
    Stage 2
    220/23X .618"/.618" 113 LSA
    The old Stage 2 had proven to be an excellent camshaft choice for cathedral port headed 5.3s and 6.0s utilizing a wide range of different turbos. 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. Whether you're putting together a budget street build with a small 7275 turbo or aiming for the fences with a Borg Warner S485, this camshaft will make sure the valve events are optimized for your pressurized application.
    Stage 3
    224/23X .618"/.618" 114 LSA
    The new BTR Turbo Stage 3 V2 cam was designed to bridge the gap between street and strip applications . The old Stage 3 had proven to be an excellent camshaft choice for cathedral port headed 5.3s and 6.0s utilizing a wide range of different turbos. 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.
    Do you have a lightweight setup with a powerglide + 5.3/6.0 that's being pressurized by an S400 (or similar size) turbocharger? If so, this cam will have you lighting the win lamps on race day.
    Stage 4
    227/24X .618"/.618" 115 LSA
    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.
