Paxton Superchargers Universal PowerHat Carburetor Hat Assembly - Polished 8PM106-018
Polished Universal Blow-Through Carburetor PowerHat for 4150-Style Carburetors
The Paxton Superchargers Universal PowerHat Carburetor Hat Assembly (PN 8PM106-018) is a cast aluminum, low-profile carb hat engineered for blow-through supercharged carburetor applications. Designed to work with Holley 4150-style 4-barrel carburetors with mechanical secondaries, this polished PowerHat delivers improved airflow stability and consistent fuel control under boost.
This assembly is compatible with popular carburetors from Quick Fuel, Demon, and Holley. Depending on boost level and engine configuration, minor carburetor modification or rejetting may be required. For most applications, Paxton recommends the Quick Fuel Q-750-BAN carburetor for reliable performance.
Diffusion Technology & Airflow Control
Traditional carb hats can create turbulence and uneven pressure distribution. The Paxton PowerHat incorporates integrated diffusion technology that conditions incoming air before it reaches the carburetor. This helps reduce common blow-through issues such as jetting instability and inconsistent fuel delivery, resulting in smoother throttle response and more predictable tuning.
Low-Profile Universal Design
With an overall height of just 3.2 inches, this PowerHat is ideal for tight engine bay and hood clearance situations. Its near-360-degree rotational capability allows flexible inlet orientation, simplifying custom supercharger ducting and plumbing layouts.
