When you pull up in the staging lanes and want to turn conversation into confrontation, you better have the BTR Stage 3 turbo cam making your valves talk! This cam is one of the most historically victorious camshafts in our turbo offerings. It has seen Drag Week, KOTS, Lights Out, No Mercy, and a myriad of other highly competitive environments, all while being a shelf offering. It offers cam events that will give the end user a bit more RPM range than the Stage 2 grind can offer. Do you have a lightweight setup with a powerglide + 5.3/6.0 that's being pressurized by an S400 (or similar size) turbocharger? If so, this cam will have you lighting win lamps quicker than you can say "BTR Sasquatch banner."
