Important Considerations

  • All stall ranges are dependent on your specific vehicle setup and tuning. Please contact us for personalized advice regarding expected stalls.
  • Considering a build? We recommend upgrading to our "Street Bandit Series" if you have modified two or more drivetrain components (such as intake, heads, headers, exhaust, cam, or gearing). For extreme power applications including Nitrous Oxide, Turbochargers, or Superchargers, the "Out Law Racing Series" is advised.
