BTR "Twin-Turbo" Camshafts, LS Applications

BTR STAGE 1 TWIN TURBO CAMSHAFT V2- The new BTR Twin Turbo STG 1 V2  was developed for use in 5.3/Hi-ram/Twin turbo street and strip combinations, although it's a versatile camshaft that performs well in a wide range of applications. Good for 5.3s and 6.0s with cathedral port heads , it also will work well in LS3 headed applications. 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. At the end of the day, if you're using a pair of smaller 58mm - 66mm turbos on your LS-based build ,and plan on putting some street miles on it, the TT Stage 1 is hard to beat.  218/23X .618/.618 113 LSA

BTR STAGE 2 TWIN TURBO CAMSHAFT V2- The new BTR Twin Turbo STG 2 V2 is the one you want to go with when you have a 6.0 or a 6.2 with 58-65mm turbos. Idle will be relatively mild, but more aggressive than stock. 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.. This is a cam that is just as comfortable delivering you to work as it is pushing you down the 1320 and turning on the win lights on race day!  222/24X .618"/.618" 113 LSA

BTR STAGE 3 TWIN TURBO CAMSHAFT V2- Unlike its smaller brethren, the Stage 3 V2 twin turbo camshaft is geared towards the drag strip specific crowd. 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.  Larger twin turbos (minimum 66mm) paired with a 6.0+ combination will easily exceed four digit horsepower territory with good fuel and tuning and the extra overlap provided will let the competition know you mean business. If you're running smaller 58-65mm turbochargers, stepping down to the Stage 2 TT cam is a better option.  226/24X, .618"/.618", 115 LSA

BTR STAGE 4 TWIN TURBO CAMSHAFT V2- The new BTR Twin Turbo Stage 4 V2 cam was designed for use in serious effort stock stroke applications.  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 with larger 70+ mm turbos , this camshaft will help you move some serious air. For you folks who may have a street/strip 408" bottom end spinning large enough turbos , this new cam can also be a very good fit, although you may want to look into our 400" Twin Turbo cam lineup. 230/25X .618"/.618" 116 LSA
