When it comes to a vacuum pump, people often overlook the simple yet useful function it can provide. This component is a simple add-on to the high performance or racing engine in your vehicle that will increase horsepower. Sounds amazing, right?
The vacuum pump replaces open element breathers and valve cover-to-exhaust hoses and crankcase evacuation systems in order to remove gases in high-horsepower applications. One of the most popular manufacturers of vacuum pumps is Aerospace Components. The crankshaft operates the Aerospace pump, which generates vacuum to alleviate pressures more successfully while assisting the engine to produce additional horsepower. On a very big engine with a small oil pan, you might notice a large power gain just with an added engine vacuum pump.
In this article, you’ll find out about vacuum pump car applications, what they are, and the benefits of installing an Aerospace vacuum pump in your car.
What Is An Aerospace Vacuum Pump?
An Aerospace vacuum pump is a US-made component meant to enable the engine to produce additional power by improving its operating process. The primary purpose of an engine vacuum pump is to release crankcase pressure. The piston ring seal is negatively impacted by crankcase strain, which could also result in drag and windage and limit the piston's ability to move freely inside the engine cylinders.
A piston's up and down movement is restricted when the crankcase is under pressure, whereas a crankcase that is not under pressure can move up and down more smoothly. The Aerospace vacuum pump lessens windage, improving overall engine performance.
Because the vacuum pump eliminates the loss brought on by drag, horsepower is released as a result. Running lower tension piston rings to reduce friction is a benefit of adding a vacuum pump, which also adds horsepower.
Across many engine types, neglecting significant windage can result in problems with the piston ring seal, including seal loss, blow-by, and excessive oil intake because the oil is kept in suspension by a "roping effect" which will not flow back to the pan. As a result of the valvetrain oil drainage being forced back up the very same route that the crankcase is already using to release pressure, too much oil is being discharged from the breathers. With the help of those components, a vacuum pump kit will help maintain a healthy piston ring, seal, and engine.
Benefits of Aerospace Vacuum Pumps
One of the key benefits of a vacuum pump car application is more horsepower. One of the things that need to be remembered is that this is a bolt-on part that allows a vehicle to produce extra horsepower without excessively modifying your car.
An Aerospace vacuum pump has several key success gains such as:
- Better ring seal because of lower crankcase stress beneath the rings
- Lower friction due to the use of lighter tension rings
- Lower windage surrounding the crankshaft
- Reduced oil leakage
- Lowered parasitic pumping waste
- Reduced cavitation and upgraded oil filtering
- Improved power due to less mixture contamination
- Reduced gas port contamination
One of the most important things to any car component is the quality with which it is made which will only add to the benefits of the given component. The high-quality 6061-T6 billet aluminum is used in all the Aerospace vacuum pump components, ensuring its safety but also market standard.
The single-piece shaft has no run-out and rolls on double-sealed ball bearings. What's important is that carbon fiber is used to make the vanes so they would be strong and have a low spinning weight. Aerospace Components provides gaskets to accommodate every vacuum pump car application, and every engine vacuum pump from this manufacturer comes with a pulley that is the right size. Low-tension rings can be used since they don't have to swipe that much oil off of the cylinder walls as well as the crankcase vacuum helps ring the seal.
Although the engine vacuum pump kit from Aerospace is applicable to passenger car engines, the most benefits are seen in high-performance and racing engines.
Increased Horsepower
A vacuum pump can increase an engine's horsepower in addition to removing oil spatter. Gains of between 15 and 25 horsepower are feasible in a common street/strip performance engine combination thanks to an enhanced ring seal. Vacuum pumps remove pressure from the crankcase. As a result, and by improving the ring seal, more combustion energy is directed to the crankshaft. Increased horsepower is achievable because of the vacuum pump's ability to improve ring sealing and enable the use of a lighter pressure oil ring for increased power.
On both motorsport and high-performance street cars, adding a crankcase vacuum pump will produce significant horsepower. When used correctly and backed by non-restrictive piping, a bigger pump may move more air and produce a higher vacuum. A single -10AN or -12AN input line is used in the majority of these cases, although on bigger engines, there may be times when two -10A input lines are used. The best result comes when the engine's optimal vacuum is reached early in the power band and kept constant throughout, and to do that, the correct pump is selected and run at the specified speed.
When it comes to V-belts, pulleys, valves, oil systems, crankcases, or any other component associated with the Aerospace vacuum pump, you should always be on the lookout to see whether it needs to be replaced. The pump can be fitted almost anywhere, but the most popular option is to attach it to the cylinder heads or the motor plate.
If the idea of adding additional power to your car with an Aerospace vacuum pump seems like a good one, JEGS is the supplier to check out. You’ll find a wide array of engine vacuum pump kits as well as individual parts from this US-based manufacturer. Aside from vacuum pumps and vacuum pump kits, other components such as disc brakes, brake lines, nitrous bottle brackets, brake pads, and more are available from the online JEGS catalog.
