If you have been around any form of racing for any length of time you have surely seen Moroso oil accumulators bolted to cars and trucks of all shapes and sizes. Those silver looking aluminum tubes have saved more engines over the years, preserved more engines over the years, and kept more racers from crying in piles of destroyed parts than nearly anything else ever made. That being said, what’s it actually doing and how does it actually work? It is one of those products that seems so stone simple on its face but in reality there’s a lot going on that is far more interesting to watch than it is for us to tell you about. Knowing this full well, Moroso built a clear version of the product to demonstrate exactly what it does under different circumstances. We’re talking about times when there’s a dip in your oil pressure because of high cornering loads, a drop in oil pressure when you lift at the end of the track and all of the sauce goes forward in the pan or there’s a loss of pressure because the engine is consuming itself.
Scott walks you through the premise behind the product, how to properly set it up, and then on their custom made test rig they put the accumulator through a variety of situations. As Scott says, this thing can be valuable for racers, hot rodders, and classic car owners. On the classic car side, it is a way to pre-lube an engine that does not see much use or has long periods of down time between uses. We saw the “director’s cut” of this at PRI and we’re happy that Moroso got it up on their YouTube page to share it with everyone else because it really is cool. It isn’t often we get to see inside parts and components to actually watch them work.
Here’s what an Moroso Oil Accumulator does and how it does it!
