This new V2 version of the BTR Twin Turbo Stage 1 camshaft 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, BTR 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 Twin Turbo Stage 1 grind is hard to beat.
