Ep 93. It's the Oil Pump Pump-Off!!

In the latest episode of Engine Masters season 6, titled "It's the Oil Pump Pump-Off!!", the team is taking on the task of comparing various oil pump designs to see which one comes out on top.

The episode begins with the team discussing the importance of oil flow and pressure in an engine. They explain that oil is necessary to lubricate the moving parts of the engine and prevent them from wearing down or seizing up. However, too much or too little oil pressure can cause problems and even damage the engine.

To test out different oil pumps, the team sets up a dyno test using a 427-cubic-inch small-block Chevy engine. They install four different oil pumps, each with a different design, and compare the results.

First up is a standard volume pump with a stock pickup. This pump is a common choice for street and mild racing engines. The team explains that a stock pickup is designed to work with the stock oil pan and oil level, so it's important to use the correct combination.

Next, they test a high-volume pump with a stock pickup. This pump is designed for use in high-performance engines that require more oil flow. The team notes that it's important to balance the oil system to prevent excessive pressure.

The third pump they test is a Milodon oil pump with a custom pickup. This pump is designed for use in drag racing engines and features a larger oil flow capacity. The custom pickup is designed to work with a custom oil pan, which allows for better oil control.

Finally, they test a Melling oil pump with a custom pickup. This pump is a popular choice among engine builders and features a high-volume and high-pressure design. The custom pickup is designed to work with a custom oil pan with increased capacity.

Throughout the episode, the team discusses the advantages and disadvantages of each pump design. They note that while a high-volume pump can provide more oil flow, it can also create excessive pressure that can damage the engine. They also discuss the importance of using the correct pickup design and oil pan to ensure proper oil control.

After running each pump on the dyno, the team analyzes the results. They look at the horsepower and torque curves to see how each pump affected the engine's performance. They also monitor the oil pressure and flow rates to determine which pump provided the best oil control.

Throughout the testing, the team provides helpful tips and insights for engine builders looking to improve their oil system. They emphasize the importance of balancing the oil system to prevent excessive pressure and ensure proper oil flow.

Overall, "It's the Oil Pump Pump-Off!!" is a valuable episode for anyone looking to improve the oil system in their engine. The team provides detailed information on oil pump design and testing, making it an informative and engaging episode for gearheads of all levels.
