Our Engine Dyno Capabilities

 

  • Complete Engine Break‑In: Controlled load cycling for new engines, ensuring ideal ring seating and oil pressure verification.
  • Full Power & Torque Testing: Measure output across the RPM range to evaluate engine performance and efficiency.
  • Fuel & Timing Calibration: Fine‑tuning carbureted, EFI, or standalone systems for optimal air/fuel and ignition curves.
  • Data Acquisition & Analysis: Real‑time monitoring of torque, horsepower, AFR, EGT, and other vital parameters.
  • Carburetor & Injection System Setup: Optimized jetting or fuel mapping to suit your engine’s displacement and cam profile.
  • Baseline & Comparison Testing: See before/after results from cam, intake, or software changes.
  • Break‑In Oil & Fluid Monitoring: We track pressure, temperature, and contamination to confirm your engine’s health during testing.

 

Why Use an Engine Dyno

Unlike chassis dynos that measure power at the wheels, our engine dyno measures true crankshaft horsepower and torque.
It eliminates drivetrain losses, giving you precise data on the engine itself. We can dial in timing, fueling, and operating ranges in a controlled environment before installation — reducing risk and saving time on final tuning.
