Superior COE specialty machining tool

Superior crankshaft

Dynamometer and Load Tests​

At the Superior engine COE, we try to implement ideas that benefit our customers while also saving them money. One of these is our three (3) water brake dynamometers that allow us to test run Superior engines under operating load. It is standard practice to load test all of our overhauled Superior engines. The Superior COE has performed load tests for various customers who want to make any necessary engine adjustments before their unit is installed at its final location.

Proven Results

COOPER CASE STUDY: A west Texas customer recently suffered a substantial crankshaft failure on their Superior high-speed separable 16SGTB engine. They were in a deep bind and needed to have their engine back online as soon as possible. The Deer Park shop was able to build an engine from scratch, test it, and paint it within a week, and then exchange and install it the following week. The customer was down for less than two weeks. There is no other company that has the parts on-hand and the experienced personnel to carry out such a task within this time period.
