Why Use an Engine Dyno Simulation?

  1. Camshaft specifications are too confusing!
  2. A real dyno test is too expensive or inaccessible.
  3. Eliminate the guesswork and find the best combination of performance parts.
  4. Know exactly what kind of horsepower and torque you’re going to get.
  5. Highly accurate results at low cost.
