Engines are mounted on massive test stands built to handle extreme heat, high-pressure exhaust, and volatile fuels. When fired, engineers measure thrust, fuel efficiency, combustion stability, and durability under real launch-like conditions. Different engines—liquid, solid, or hybrid—are tested in their own ways. For liquid engines, super-cold fuels like liquid hydrogen and oxygen are pumped in and ignited to produce controlled thrust. Hundreds of sensors monitor pressure, temperature, vibratio

Equipped with a host of parts from Holley Performance Products, we utilized a PRW Industries Inc. engine test stand for the Spark Plug Wire Challenge portion of the 10K Drag Shootout. The test stand has a collapsible design with all the wiring and gauges you need to run an engine in your shop. You can save time and money with the ability to fire up an engine before bolting it into your car or truck. | Horsepower Wars | Facebook
