4150 750CFM SC XP Carb Draw Thru Design

The Holley 4150 750 CFM Carburetor with Draw-Through Design is a high-performance 4-barrel carburetor specifically engineered for high-displacement supercharged and turbocharged engine applications. This carburetor is ideal for serious engine builders and hot-rod enthusiasts looking to maximize fuel delivery and atomization in their setups.

Designed for forced-induction powerplants, this 750 CFM unit features a square-bore compatibility and dual inlet configuration, ensuring optimal flow capacity. The draw-through design allows the supercharger or turbo to pull the air-fuel charge through the carburetor, necessitating robust internal construction to withstand pressure differentials and sustained boost conditions.

With a mechanical secondary system that provides progressive fuel delivery, this carburetor prevents bogging and maintains combustion efficiency across the RPM range. The no-choke design eliminates cold-start complications, making it a reliable choice for high-performance applications in both small-block and big-block platforms.
