Engine Dyno Tuning & Testing




There’s a reason why Golen Engine draws gear heads from as far away as Boston to check out our dyno tuning services. We’re simply the best, most capable source or this type of testing to get the absolute highest levels of performance out of your engine. Not only do we use advanced equipment and techniques, but also we provide you with real-time data about how well your engine performs. Our reports include data on torque and horsepower as well as air-fuel mixtures, gas mileage and more. You’ll also learn about the differences at steady and changing speeds, which is crucial to monitor before performing full RPM testing.
Here at Golen Engine we offer complete performance dyno tuning and break-in services for both street and full race engines. Our dyno tuning in Hudson, NH, can handle up to 1600hp with our two in house Superflow SF-902 Dynamometers. We offer local dyno tuning services for a number of aftermarket EFI systems such as the Holley Dominator and Fast EFI Systems to name a few and specialize in LSx dynamometer testing but can tune aftermarket EFI on just about any domestic V-8 engine. For all you old school carb guys if we can’t convince you to convert to EFI then we have everything needed to tune your Holley to run properly and make max power.

Questions? Give us a call at 1-800-591-9171 or Contact Us and we’ll get in touch with you right away.

Benefits of having your engine broken in and tuned on the dyno:

  • Seat Piston rings
  • Retorque all fasteners
  • Check for leaks
  • Inspection of oil and filters
  • Tune fuel and ignition systems for optimal performance


We will run your engine for a complete break in cycle monitoring all engine vitals over the course of a few hours. Once the break in cycle is complete will change the oil, inspect the oil filter and re torque all fasteners. At this point we will run the engine between 10-15 full rpm runs while recording all engine vitals and looking for consistent power readings from run to run. We will provide you with a video of your engine dyno testing and accompany it with printed copies of the dyno readings for your records. Customers are always welcome to visit our shop for dyno testing in New Hampshire and see their engines run on the dyno and take them home the same day, However in-person dyno services are by appointment only.
