Review HOLLEY/QFT Pair Of Double Pumper Roots Type Blower Lightweight Aluminum fits 650

The Holley/QFT SHP650 650 Double Pumper Roots Blower is a high-performance, fuel-injected supercharger system designed for serious automotive enthusiasts seeking to boost the power output of their engines. This roots blower, manufactured by Holley Performance Products in collaboration with QFT (Quad Force Induction Technology), is an advanced engineering solution for delivering exceptional power gains and improved engine response.

The SHP650 is a 650 cfm (cubic feet per minute) double pumper roots blower, which means it features two independent, parallel-running rotor groups. This design allows the blower to generate more vacuum and pressure than a single pumper, ultimately resulting in increased power and torque across the entire RPM range. The large 650 cfm size ensures that the engine receives an ample supply of air for efficient combustion, leading to significant power gains.

The Holley/QFT SHP650 is compatible with various fuel systems, including EFI (Electronic Fuel Injection) and carbureted applications. It comes equipped with a Holley 255LB EFI fuel pump to ensure a consistent fuel supply for the increased airflow. The system also includes a Holley 3-bar MAP sensor, making it a complete fuel-injected supercharger kit.

One of the most impressive features of the SHP650 is its Quad Force Induction Technology (QFIT). This innovative design involves four intake runners, which are arranged in a unique "square" configuration, allowing for better flow distribution and increased efficiency. The roots blower's rotor housing is also CNC-machined from billet aluminum for improved durability and precision.

Installation of the Holley/QFT SHP650 is made easier with its modular design, which includes pre-assembled components and clear installation instructions. The blower comes with a polished aluminum drive pulley, pulley spacer, and all necessary hardware for a straightforward installation process. Additionally, the kit includes a belt tensioning system to ensure optimal belt tension for optimal performance.

The Holley/QFT SHP650 650 Double Pumper Roots Blower is a powerful and efficient supercharger system designed for serious power gains and improved engine response. Its unique features, such as the double pumper design, Quad Force Induction Technology, and compatibility with various fuel systems, make it a top choice for automotive enthusiasts looking to take their engine performance to the next level.

The Holley/QFT SHP650 650 Double Pumper Roots Blower is a popular choice for automotive enthusiasts looking to enhance the performance of their vehicles. This supercharger offers several advantages and disadvantages that are essential to consider before making a purchase.

Advantages:

1. Increased Power: The Holley/QFT SHP650 supercharger can significantly boost power output, providing a noticeable improvement in engine performance. This is ideal for those seeking to enhance the acceleration and overall power of their vehicle.

2. Self-Contained Design: The self-contained design of the Holley/QFT SHP650 supercharger makes it easier to install as it requires no external oil or water lines. This can save time and money during installation.

3. Durability: The roots blower design is known for its robustness and reliability, making it a popular choice for high-performance applications. The Holley/QFT SHP650 supercharger is no exception, as it is constructed from high-quality materials that can withstand the demands of increased power output.

4. Air-to-Air Intercooling: The included air-to-air intercooler helps to reduce the temperature of the intake air, which can improve combustion efficiency and power output.

Disadvantages:

1. Size: The Holley/QFT SHP650 supercharger is relatively large and may require modifications to fit certain vehicle applications. This could result in additional installation time and costs.

2. Noise Level: Roots-type superchargers are known for their loud operation. The Holley/QFT SHP650 supercharger is no exception, and users may need to invest in sound deadening materials or custom exhaust work to reduce the noise level.

3. Expense: The Holley/QFT SHP650 supercharger is a high-performance component and comes with a corresponding price tag. This may be a significant investment for some automotive enthusiasts.

Conclusion:

The Holley/QFT SHP650 650 Double Pumper Roots Blower offers several advantages, including increased power, self-contained design, durability, and air-to-air intercooling. However, it also has some disadvantages, such as size, noise level, and expense. Ultimately, the decision to purchase this supercharger depends on the individual's priorities and budget. If power output and reliability are the primary concerns, the Holley/QFT SHP650 supercharger is an excellent choice. However, if size and noise level are major considerations, alternatives such as centrifugal superchargers may be a better option.

Recommendation:

For those seeking a powerful, self-contained, and reliable supercharger for their high-performance vehicle application, the Holley/QFT SHP650 650 Double Pumper Roots Blower is a strong recommendation. However, it is essential to consider the potential size and noise level implications and weigh them against the benefits before making a purchase. Additionally, carefully assessing the installation requirements and costs is crucial to ensure a successful installation process.

Details:

They are NOT for Blow-Through Supercharger or Turbocharger use. No more fumbling with sight plugs. This is one of my custom builds. Holley polished lightweight aluminum HP main body with.

These ARE for Draw-Through, Roots Supercharger use only. Lightweight aluminum racing fuel bowls with sight windows that will not yellow. Teflon coated throttle shafts. The jetting is 70 up front with a 5.5 Hg high-flow power valve, and 78 in the rear valve circuit blocked.

This is NOT the cheap Chinese knock-off junk sold under brand name Pro Comp. They will easily support 500-900 horsepower on a draw-through Roots blower. Performance aluminum metering blocks that are custom calibrated for maximum performance. Heavy duty clear anodized billet aluminum base plate that is much stronger than a cast Holley piece.

Heres a list of features;. Externally referenced power valve. The 3/16 vacuum port on the passenger side of main body must be connected to a source BELOW blower base manifold using common tubing. Thanks, Steve.

The mounting gaskets are included as shown. They have been assembled with high-flow .110 needle seat assemblies, 30cc pumps, #31 squirts pink pump cams, non-stick bowl and block gaskets, nylon screw gaskets.
