Designed for factory and aftermarket GM blower applications upgraded to a 112mm throttle body, this system supports 50–200 horsepower out of the box and flows over 400 horsepower with additional jetting. Single Plate Design for Maximum Distribution This system utilizes a single billet 112mm nitrous plate featuring six nitrous discharge ports and six fuel discharge ports. The multi-port design ensures complete saturation of the intake charge and promotes consistent cylinder-to-cylinder fuel and nitrous distribution — critical for reliability and performance at elevated power levels. Blower-Specific Engineering The injection plate bolts directly to GM LT1, LT4, and LT5 blower inlets that have been modified from the factory 87mm opening to a 112mm opening using the OEM 104mm x 70mm bolt pattern. The plate then allows any 112mm throttle body using the 126mm x 70mm bolt pattern to bolt directly to the nitrous plate. The system is also compatible with aftermarket blowers designed for direct-mount 112mm throttle bodies, including Kong and Whipple applications. This eliminates the need for throttle body adapter spacers while integrating a high-flow nitrous injection solution into a single compact assembly. High-Quality Construction The injection plate is CNC-machined from T6061 billet aluminum, finished in a durable black anodize, and CNC engraved for long-lasting appearance and easy identification. Every Nitrous Outlet plate is flow-tested to verify proper operation and consistent flow characteristics prior to shipping. Jetting Included The system includes jetting for 50, 100, 150, and 200 horsepower levels. While capable of flowing over 400 horsepower, additional jetting options are available separately. The system is fully compatible with gasoline or E85 with appropriate jet changes. Application GM LT1, LT4, and LT5 supercharged engines OEM GM blower inlets modified to 112mm Aftermarket 112mm throttle bodies Aftermarket 112mm direct-mount blower inlets Gasoline or E85 applications (with proper jetting) Additional InformationWhenever nitrous oxide is added to a vehicle, it is recommended to use colder spark plugs and a method of ignition timing retard.
