Holley Terminator X Platform

Holley has announced it has expanded the popular Terminator X platform to allow compatibility with even more applications.


Holley’s new Stealth 4150 models resemble a Holley XP carburetor but have four 100lb./hr. injectors hidden inside the throttle body. The external ECU can be fully programmed with four inputs and four outputs as well as the ability to handle a single stage of nitrous, or integrated boost control. Following that up, Terminator X MAX systems have been announced for both Gen III Hemi Drive-By-Wire and Ford Modular 2V/4V platforms.
