Dyno Test:

All of Revivas 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 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. Reviva also tests oil and coolant temperature; monitors crankcase pressure, oil and turbo boost pressures; and tests fuel consumption.
