A straightforward solution to solving fueling issues in GM GenV LT engines is to incorporate Port Fuel Injection. TooHighPsi's LP (low profile) Plates are designed to add secondary port injection to your LT1/LT4 Gen V engine fitted with a Magnuson TVS2650 with the minimum amount of vertical height increase of the supercharger or intake manifold.

LP-Plates are a direct bolt on for the LT4 CTSV and LT1 Camaro SS with Magnuson TVS 2650 with no other modification required. C7 Z06 Corvette and ZL1 Camaro require the use of our Billet 2650 supercharger lid to provide adequate hood clearance, or the hood needs to be modified for fitment. They can also be used with the stock LT4 TVS1740 supercharger provided the valve cover requirements below are met.

Valve Cover Requirements - Our LP-Plates are designed to work with our THP 2-pc Billet Valve Covers or stock GM valve covers that have been modified to fit a Magnuson TVS2650R (ignition coils relocated). If you have aftermarket valve covers, please call us to verify fitment.

Injector Type: The LP-Plates require the use of LS1-style 60mm "LONG" injectors that have the coil connector at the top of the injector. Injector options can be found here: FUEL INJECTORS – TooHighPsi Engineering

All kits include 2 sets of plates, brackets, fuel rails with your choice of -6AN or -8AN end fittings, O-ring gaskets and all necessary hardware to install under your supercharger (injectors not included). LT4 options adds PCV spacer connector for under supercharger.

Mounting hardware options: In early 2022, Magnuson changed the design of the 2650 supercharger housing casting. The original design was produced with 3 pieces (center rotor housing section and 2 intercooler pod castings bolted to the sides of the center) The later 2022+ housings are all one piece and have a slightly thicker flange, please select the correct housing style to ensure we provide the correct length bolt for your application.

Please call or email us with questions about your specific application!
