When an engine sits, the oil film slowly drains off the internal component contact surfaces and out of the oil passages, back into the oil pan. Without pre-luberication, your engine will be running with little to no oil pressure for the first few seconds as the oil pump refills the passages. This can be further pronounced on Vipers where they are not used as daily driven vehicles. It is during this time that most damage can occur.
Did you know that the Viper V10 has no camshaft bearings and the cam rides directly in the aluminum block? Our '94 RT/10 with 11,000 street miles and no track time had a scored camshaft bore, requiring it to be bored out and a service cam with larger journals had to be installed.
This system is designed to simulate the oil pump by introducing pressurized oil into the oil galleys before the engine is started, prefilling them and prelubricating your engine.
This is a complete kit with all the components and instructions needed for installation. Wiring and installation is straight-forward. There's an electric oil control valve at the tank activated by a LED lighted switch mounted in an out of the way location inside the car. I put my switch inside the center vent under the steering wheel. The oil line T's into the stock oil cooler line.
Regarding how long it will hold a charge, there's no place for it to leak pressure with the new design except the valve, which is rated for hundreds of thousands of cycles. If the valve did seep pressure over years, the oil would slowly go from the tank back into the engine. That's worst case senario.
