BTR LSA/LS9/Roots Supercharged Camshafts, LS Applications

BTR PDS STAGE 1 TORQUE CAMSHAFT- This new version of our Stage 1 PDS camshaft makes more power and torque everywhere in the curve compared to our legendary PDS cams. Developed in house, we went back to the drawing board and found more power and torque even with the use of less intake duration.These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards. 217/23X, .619/.607, 114 LSA

BTR PDS STAGE 2 TORQUE CAMSHAFT- This new version of our Stage 2 PDS camshaft makes more power and torque everywhere in the curve compared to our legendary PDS cams. Developed in house, we went back to the drawing board and found more power and torque even with the use of less intake duration.These new BTR lobe designs were Spintron and Engine Dyno tested to achieve the highest overall power curve while also maintaining strict valvetrain stability and durability standards. 221/24X, .619/.617, 113 LSA

BTR PDS STAGE 3 TORQUE CAMSHAFT FOR 1.8 ROCKER- The PDS Stage 3 Torque camshaft for 1.8 rocker arm applications was designed for those customers wanting good low to mid rpm range torque, without sacrificing top end horsepower. This cam has a slightly more aggressive idle than before, yet still provides good drivability. This cam works well with stock long blocks and stock or ported blowers, and also works well using up to a 150 shot of nitrous. 226/25X .644"/.644" 112.5 LSA

BTR PDS STAGE 4 CAMSHAFT FOR 1.8 ROCKER- The most aggressive camshaft Brian Tooley Racing offers for GM LSA & LS9 engines. This cam is recommended when looking for more power than our Stage III application offers and has an ultra-aggressive idle. It is perfect for use in high rpm, Max Effort stock displacement, or 4" stroker applications when paired with a Magnuson 2650 or Whipple 3.0 PDS superchargers. We recommend the use of aftermarket or ported OEM cylinder heads and larger throttle bodies when used with higher boost levels. 229/25X .644"/.644" 116 LSA

BTR RED HOT CAMSHAFT- BTR is proud to introduce our newest camshaft offering for 5.7, 6.0, and 6.2 LS engines. Affectionately dubbed The Red Hot Cam, we have put this camshaft in a wide variety of engine combos, and it was spicy enough to make excellent power in both boosted and N/A applications. Things really heated up once it was installed and running on the engine dyno. It showed excellent power gains over our existing Stage 2 PDS and LS3 Centrifugal cam profiles even with less intake duration. Using BTR lobes designed in house, this cam had just the right amount of kick that combined both great stability and durability during Spintron testing. Scoring a 1.5m SHU (Think Carolina Reaper and Pepper Spray) on the Scoville Scale, this cam is sure to add some heat to your build! 221/24X, .619/.617, 113 LSA
