AMR300 Supercharger: Compact Performance for Small Engines

Introduction

The AMR300 supercharger is a compact, mechanical Roots-type supercharger designed for small engine applications. Manufactured by AISIN, this supercharger is ideal for enhancing the performance of engines with displacements ranging from 0.5 to 1.3 liters. Whether you're working on a go-kart, ATV, snowmobile, or a small car, the AMR300 offers a reliable and efficient solution to boost engine power.

Design and Specifications

The AMR300 features a lightweight and compact design, making it suitable for tight engine bays. Its key specifications include:

• Type: Roots-type positive displacement supercharger
  
• Displacement Capacity: Suitable for engines between 0.5L and 1.3L
  
• Weight: Approximately 5 kg (11 lbs)
  
• Dimensions: 17.5 cm wide and 10.5 cm tall
  
• Pulley Options: Available with various pulley configurations (e.g., 4PK, 5PK, 6PK) to suit different setups
  
• Lubrication: Requires periodic oil changes; some models come pre-filled with oil, while others may need to be filled before use
  

Performance and Efficiency

The AMR300 is known for its simplicity and reliability in small-scale applications. However, it's important to note that, like many Roots-type superchargers, it operates with lower efficiency compared to other types such as twin-screw or centrifugal superchargers. This lower efficiency can lead to higher intake air temperatures, which might necessitate additional cooling solutions like intercoolers to maintain optimal engine performance.

Installation Considerations

Installing the AMR300 supercharger requires careful attention to several factors:

• Pulley Ratio: The supercharger's pulley size and the engine's crank pulley size determine the boost pressure. For instance, a 1:1 pulley ratio typically yields around 11.9 psi of boost.
  
• Air Intake and Exhaust: Proper routing of the intake and exhaust systems is crucial to ensure efficient airflow and prevent heat buildup.
  
• Mounting: Custom brackets or mounts may be necessary to securely attach the supercharger to the engine.
  
• Belt Alignment: Ensuring that the drive belt is properly aligned and tensioned is essential to prevent slippage and wear.
  

Applications

The AMR300 supercharger is versatile and can be used in a variety of applications:

• Go-Karts and ATVs: Provides a significant power boost, enhancing performance for racing or recreational use.
  
• Snowmobiles: Improves acceleration and top speed, making rides more thrilling.
  
• Small Cars: Ideal for engine swaps or custom builds, offering increased horsepower and torque.
  
• Custom Projects: Perfect for DIY enthusiasts looking to add forced induction to their small engines.
  

Purchasing Options

The AMR300 supercharger is available from various online retailers:

• Amazon: Offers new and refurbished units with different pulley configurations.
  
• eBay: Provides a range of options, including OEM and aftermarket units, with varying prices and conditions.
