All of RAMPTECH® Complete Drop-In Engines are 100% dyno tested prior to shipment. Computer controls ensure that each engine dyno test is conducted under standard, repeatable settings. Every engine is run through a warm up cycle; three separate cruise segments simulating light, medium and heavy throttle conditions; maximum torque and horsepower tests; both high and low idle tests; and a black light leak detection test with dyed oil, coolant, and fuel.
WITH NEW OEM HEUI INJECTORS
Remanufactured injectors are one of the most common causes for fuel system failures in this engine throughout the industry. As a quality enhancement, RAMPTECH® engine builders install new HEUI injectors on all 7.3L DI Long Block Supreme and Complete Drop-In engines. These new injectors, from the OE manufacturer, have tungsten coated plungers, which is an improvement over some earlier OE injectors.
