INTAKE LOBE LIFT @ TDC: 0.05129
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.
OR IF YOU WANT TO RUN A CENTRIFUGAL SUPERCHARGER
BTR CENTRIFUGAL STAGE 2 CAMSHAFT
221/24X, .619/.617, 113 LSA
INTAKE LOBE LIFT @ TDC: 0.04730
This new version of our Stage 2 Centrifugal camshaft makes excellent power and torque everywhere in the curve. 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.
E85 fuel is highly recommended. The dyno sheet below was with a LS3 short block, GMPP ported LS3 heads, BTR Trinity intake manifold, Procharger F1A supercharger. 24.5psi boost @ 7300rpm, E85 fuel. Tested in house on BTR’s Superflow dyno.

Description
Cylinder Heads are resurfaced to assure a proper sealing surface with the block and a finish compatible with today’s new gasket materials. New valves, springs, rockers, retainers, locks, seals, and if needed seats and guides, are installed. Valve height is miked and every head is vacuum tested to assure correct valve seating. Every cylinder head recieves a premium 3-angle valve job. |
Cylinder Blocks are magnetic particle inspected for cracks or imperfections. Cylinders are bored and honed and inspected to precise tolerances. Torque plate honing is performed on specific engines to eliminate cylinder head distortion after the head is bolted and torqued to the block. This process eliminates a major cause of engine blow-by. Block surfaces are machined and then inspected to ensure proper finish. |
Camshafts are inspected and precisely machined to provide correct lift. We only use new camshafts, lifters, and camshaft bearings in all our assemblies. |
Connecting Rods are machined to O.E.M. specifications and honed to the standard diameter of original equipment for even distribution of stress on the bearings. New bushings are installed and machined in all bushed rods. Every rod is carefully inspected for bend and twist as are all remanufactured parts. |
