Magnuson 2650 Holley Throttle Body Adapter by TooHighPsi

Description The TooHighPsi Engineering Throttle Body Adapter is designed for builders who demand maximum airflow and perfect fitment when upgrading their LS engine with a Magnuson 2650-based supercharger. This precision-machined adapter allows seamless installation of the Holley Pro Stock Throttle Body, part #112-123 onto the inlet of the Magnuson Hot Rod 2650 or Mag Drag 2650 supercharger. Whether you are building a high horsepower street car, drag setup, or competitive race program, this adapter ensures your supercharger receives the unrestricted airflow it needs to perform at its peak. Crafted in the USA from high-quality billet 6061 aluminum, the TooHighPsi adapter provides exceptional strength and durability while maintaining optimal internal airflow characteristics. The smooth CNC-machined surfaces promote laminar flow and reduce turbulence, helping the Magnuson 2650 supercharger respond faster and produce more consistent power throughout the RPM range. If you’re chasing every last bit of performance from your LS platform, this adapter delivers the precision engineering and reliability needed to support serious boost. This throttle body adapter also works with the COPO Camaro 2650 systems, giving racers and performance enthusiasts a versatile solution that fits multiple configurations. The bolt-on design ensures a clean, secure seal between the throttle body and the supercharger inlet, preventing boost leaks and maintaining stable manifold pressure under heavy load. Installation is straightforward, making it a practical upgrade whether you’re assembling a new engine package or enhancing an existing Magnuson setup. TooHighPsi Engineering designed this adapter to support the airflow demands of today’s high performance LS builds. By pairing the proven Holley 112-123 throttle body with the efficient Magnuson 2650 rotor pack, you’re able to take full advantage of increased inlet area, improved throttle response, and enhanced volumetric efficiency. For builders looking to maximize horsepower, torque, and tuning flexibility, this adapter provides a simple but critical improvement to any Magnuson Jackshaft 2650 equipped LS engine.
