BTR BTR-PDSSTAGE4 PDS Stage 4 Camshaft V2, LSA/LS9, 3-Bolt

Stage 2- This new version of BTR's Stage 2 PDS Camshaft makes more power and torque everywhere in the curve compared to their 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. Hydraulic Roller. Cam Bolt Style: Three Bolt. Gen III/ Gen IV LS. Increased Power. Increased Torque. Stage 3- The V2 PDS Stage 3 Torque camshaft 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. 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. E85 fuel is highly recommended. Hydraulic Roller. Cam Bolt Style: Three Bolt. LSA/LS9. Low to mid rpm torque. More aggressive idle. Stage 4- 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. This cam uses ultra stable lobes for higher RPM potential, and has proven to be extremely durable in testing. Hydraulic Roller. Cam Bolt Style: Three Bolt. GM LSA/LS9. Ultra-aggressive idle. 229/25X, .636"/.636", 116 LSA.
