DYNO BREAK IN SERVICE

We offer an extensive  dyno break in service for our Jeep 4.0 engines to ensure that it is running properly before you install it into your Jeep. Using our two brand new Superflow SF-902 Dynamometers 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, we 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 pulls 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 running on the dyno and accompany it with copies of the dyno readings for your records. Customers are always welcome to visit our shop and see their Jeep engines run on the dyno and take them home the same day, this service is by appointment only.
