REVIVA’S DYNO TEST
All of Reviva’s 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; and a black light leak detection test with dyed oil, coolant, and fuel.
