Review MOROSO Vacuum Pump Vane High performance Engine Crankcase Racing Component

The **Moroso 22640 Vane High-Performance Engine Crankcase Racing Vacuum Pump** is a meticulously engineered, high-reliability component designed to deliver superior performance and precision in high-stress automotive applications, particularly in racing and performance engine builds. Built to exacting standards, this vacuum pump leverages a robust vane-type design, ensuring consistent and efficient air evacuation from the crankcase while minimizing internal friction and wear. Its compact yet durable construction incorporates high-grade materials, including precision-machined aluminum housing and reinforced vanes, which are engineered to withstand the extreme demands of forced induction, high RPM operation, and prolonged use under intense thermal and mechanical loads. The pump s internal sealing system utilizes advanced elastomers and labyrinth seals to maintain optimal vacuum levels while preventing oil migration and contamination, a critical feature for maintaining engine longevity and performance in aggressive driving conditions.

Ideal for a wide range of high-performance engines, from naturally aspirated powerplants to turbocharged and supercharged setups, the Moroso 22640 excels in applications where reliable crankcase ventilation is essential for preventing oil dilution, reducing blow-by, and ensuring smooth operation under extreme conditions. Its high-flow design allows for rapid and efficient crankcase pressure regulation, which is particularly beneficial in engines running at elevated RPMs or under heavy loads, where traditional vacuum pumps may struggle to keep up. The pump s compatibility with Moroso s extensive line of performance accessories, such as oil catch cans and PCV systems, makes it a seamless fit for comprehensive engine management solutions, allowing tuners and racers to optimize airflow and minimize emissions without sacrificing power or reliability.

Beyond its technical prowess, the Moroso 22640 is celebrated for its ease of installation and integration into existing engine bay layouts. Its standardized mounting pattern and straightforward connection points ensure quick and hassle-free installation, even in tight or confined engine compartments. Whether retrofitting an older high-performance engine or building a fresh race engine from the ground up, this vacuum pump provides a dependable foundation for maintaining crankcase integrity and supporting overall engine health. With a reputation for durability and performance, the Moroso 22640 is a trusted choice among professional racers, tuners, and enthusiasts who demand nothing less than peak efficiency and longevity from their engine components.

### **Moroso 22640 Vane High-Performance Engine Crankcase Racing Vacuum Pump: Pros and Cons**

1. **High Performance and Efficiency** Designed for high-flow applications, this vacuum pump delivers strong suction, making it ideal for engine dynos, carburetor tuning, and performance testing. Its vane design ensures consistent airflow and minimal pulsation.

2. **Durability and Build Quality** Moroso is a well-known brand in automotive performance, and this pump is built to withstand heavy-duty use. The crankcase construction is robust, reducing the risk of oil leaks or mechanical failure under high loads.

3. **Compatibility with Racing and High-Performance Engines** Suitable for use with forced induction setups (turbocharged or supercharged engines), nitrous oxide (NOx) systems, and engine brake (E-brake) applications. Works well with Moroso s other performance products, such as fuel pumps and pressure regulators.

4. **Adjustable and Reliable** Features an adjustable suction control, allowing users to fine-tune performance based on specific engine needs. The pump is also known for its reliability in long-term use, especially in racing environments where consistency is critical.

5. **Easy Installation and Maintenance** Designed for straightforward integration into engine bay setups. Requires minimal maintenance regular oil changes (using recommended oil) are sufficient to keep it running smoothly.

6. **Widely Available Support** Moroso has a strong reputation in the performance automotive community, meaning parts, replacements, and technical support are readily accessible.

7. **Versatile Applications** Beyond engine dynos, it can be used for carburetor testing, fuel system diagnostics, and even some air brake systems in racing vehicles.

1. **Noise Levels** Like most high-performance vacuum pumps, this model can be quite loud during operation. While not excessively so, it may require soundproofing or placement away from driver/passenger areas in a vehicle.

2. **Oil Consumption** Vane pumps require periodic oil changes (typically every 50 100 hours of use, depending on conditions). Neglecting this can lead to reduced performance or premature wear. The pump does not self-lubricate indefinitely.

3. **Power Draw** Running continuously, especially on high-performance engines, can draw significant electrical power. Ensure your vehicle s electrical system (or external power source) can handle the load to avoid voltage drops or fuse failures.

4. **Cost Relative to Basic Models** While not excessively expensive, it is more costly than basic vacuum pumps (e.g., those used for simple carburetor testing). The price reflects its high-performance capabilities, which may not be necessary for casual use.

5. **Potential for Oil Leaks** If not properly installed or if seals degrade over time, oil leaks can occur. Regular inspections of connections and gaskets are recommended to prevent contamination of the engine bay.

6. **Limited Lifespan Under Extreme Conditions** While durable, prolonged use under extreme temperatures or with contaminated air (e.g., dusty environments) can shorten its lifespan. Proper filtration and maintenance are essential.

7. **Not Ideal for Low-Volume Applications** If you only need a vacuum pump for minor tasks (e.g., occasional carburetor cleaning), a simpler, less expensive model may suffice. This pump is best suited for heavy-duty, frequent use.

### **Conclusion**

The **Moroso 22640 vane vacuum pump** is a high-quality, reliable choice for serious racers, tuners, and performance enthusiasts who require a robust, high-flow vacuum solution. Its strengths lie in durability, adjustability, and compatibility with demanding applications like forced induction and nitrous setups. However, it is not without drawbacks primarily noise, maintenance requirements, and higher power consumption which may be less of a concern for casual users.

If you are running a **high-performance engine, turbocharged/supercharged setup, or a nitrous system**, this pump is an excellent investment. For **basic carburetor testing or infrequent use**, a more affordable alternative might be preferable.
