Goliath High Pressure Fuel Pump & XDI 50% Injector Bundle

Introducing the ultimate power upgrade bundle from Katech. Featuring XDI 50% Injectors and the Stanadyne/Katech Goliath High Pressure Fuel Pump. This bundle is designed to enhance fuel delivery and optimize performance for high horsepower applications, offering reliability and precision engineered fueling solutions.

XDI 50% Injectors: XDI 50% Injectors, specifically designed for GM's Gen V LT series engines. These injectors deliver a substantial 50% increase in flow over stock LT4 injectors, ensuring ample fuel delivery capacity for high horsepower demands without the need for additional fuel systems. Built upon the foundation of the original GM LT4 injector, they provide a straightforward drop-in installation with minimal adjustments to existing ECU injector characteristics. Each injector undergoes meticulous testing at 100bar and 200bar on OEM equipment at XDI, ensuring precise flow matching within ±0.5% for consistent performance. Tested on fully instrumented engines for superior cylinder distribution and stability at pressures up to 3200psi, these injectors are fully E85 compatible, making them a versatile choice for performance enthusiasts.

Stanadyne/Katech Goliath High Pressure Fuel Pump: Developed in collaboration with Stanadyne, the Goliath High Pressure Fuel Pump is the cornerstone of this bundle, addressing the fuel flow limitations of the stock Gen V LT mechanical fuel pump. Engineered for power outputs exceeding 1500hp on gasoline and 1300hp on E85, this pump features a 12mm bore size and is capable of operating at up to 220bar pressure. It boasts improved volumetric efficiency and high RPM stability with an enhanced spring design, validated through rigorous testing on Katech's in-house engine dyno. With support for cam lifts exceeding 8.00mm, it ensures reliable and consistent fuel delivery under extreme conditions.
