This cam is recommended for street/strip type applications looking for more power and rpm , and offers an aggressive idle. This cam uses ultra stable lobes for higher RPM potential, and was designed to be extremely durable at high rpm when combined with a lightweight valvetrain.  237/25X .619"/.619" 117 LSA

BTR 400+ MEDIUM TWIN TURBO CAMSHAFT- The new BTR MEDIUM Twin Turbo cam was designed for use with twin 76-80 mm setups or up to a single 102mm turbo in 388-427 cubic inch combos. This cam is recommended for more serious street/strip type applications looking for maximum power and rpm , and offers an aggressive idle. This cam uses ultra stable lobes designed in house and Spintron tested for higher RPM potential, and was designed to be extremely durable at high rpm when combined with a lightweight valvetrain.  241/26X .619"/.619" 116 LSA

 BTR 400+ BIG TWIN TURBO CAMSHAFT- 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. The new BTR Big Twin Turbo cam was designed for use on 82mm or larger twin turbo setups or single 102-106mm turbos in 400-427 cubic inch combos. This cam was designed for use in high horsepower,max effort applications looking for more power at higher rpm , and offers an ultra-aggressive idle. This cam has the potential to push a 400" engine well over 2000 rwhp and into the 6 second range in the quarter mile. This cam uses ultra stable lobes designed in house and Spintron tested for higher RPM potential, and was designed to be extremely durable at high rpm when combined with a lightweight valvetrain. 246/26X .619"/.619" 115 LSA

Due to higher rpm potential combined with greater cylinder pressure from boost BTR recommenda the use of our SK703 spring kits, larger diameter hardened pushrods, and a quality lifter such as a Johnson ST2116LSR or ST2126LSR.
