Weapon-X Chevy Camaro 2016-2022 GEN 6 LT1 LT4 Secondary Port Injection Kit

There are many options available for Weapon-X SPI kits. If you have any questions please email [email protected] or call 760-586-5617.

Let's start off with the basics; port injection is the way engines were fueled since the 80s with an electronic ignition based fuel supply. The fuel injector is located in the intake manifold or on a positive displacement supercharger. When the signal is supplied, the injector opens and the amount of fuel sprayed depends on a plethora of parameters (ultimately by the Gen IV LS engines), but to dumb it down, the milliseconds the injector is open, the size of the injector in lbs/hr or cc's, and the fuel line pressure supplying fuel to the injector from the tank to the fuel rails. The fuel sprays through the ports in the cylinder head and travels by air entering the engine and travels through the valves into the cylinder where it is ignited and you have your robust combustion. It was always relatively easy to make big power numbers then, larger pump to supply the fuel to the engine and larger injectors to spray that fuel into the ports was about all it took as long as you had the capabilities to program the added fuel. Now, what is Direct Injection? As the technology evolved and emissions regulations became more and more stringent, direct injection hit the automotive world stage. Direct injection is very similar to port injection until the fuel supply reaches the engine, then it goes through a second "high pressure" fuel pump, driven off of the camshaft, which increases the fuel pressure from 70 PSI to nearly 3,000 PSI! The lack of pumps and injectors capable of reaching those pressures made it extremely difficult to achieve big power numbers safely or running ethanol-based fuels which are very inexpensive higher octane fuel right out of the pump. 

The Solution: Weapon-X Secondary Port Injection Kit.

This is a complete fuel solution from the tank to injector tip including the secondary controller and tuning software as well as support. Not everyone needs port injection for moderate power of course and they use all of the other options on customer builds as well, but for big power gains/goals, the WEAPON-X SPI Kit is a great bang for the buck and allows for future growth.

DETAILS
Plug and Play Harness for your vehicle
Low Side Kit with Pump, lines, fittings, etc
Flex Fuel Sensor
Fuel System for your specific application with rails for Whipple/Procharger/LT4 Eaton blower, lines, fittings, regulator
FIC Fuel Injectors
Optional supercharger manifold port injector bung modification
Weapon-X also has patents pending on the port injection kit itself as well as port bung modifications for the Edelbrock 2650, Magnuson 2650, Whipple 2.9L and Procharger manifolds, as well as the way they're doing it with the 1740 Eaton supercharger and Magnuson 2300. So as a result, they offer port injection bung modifications to your existing Whipples and Procharger manifolds!
