The first step of this process was to carefully measure the intake manifold and the various components of the fuel injection. By performing these calculations, Richard and Mike found that if they placed three injectors per side vertically and one at a slight angle, and by using specially designed fuel rails and a military spec electrical connector, they could likely accomplish their goal of hidden electronic port injection. Follow along and we'll show you how they turned this theory into reality.
Since there will be wiring...
Since there will be wiring inside the intake, a connector had to be found that would withstand the heat and manifold vacuum created by this application. While researching this issue, Richard found a military style connector that utilizes an O-ring for vacuum seal. Even nicer, the connector fit right into one of the factory core plug locations in the intake.
With the injectors and IAC...
With the injectors and IAC installed and the plumbing complete, it's starting to look a little busy. Next the injectors must be wired to the connector.
With the plumbing and wiring...
With the plumbing and wiring complete, you can see the fuel injection components fit nicely into the cross-ram. Although they do take up space, these intakes offer plenty of plenum volume so performance shouldn't be compromised.
To hold the fuel rails in...
To hold the fuel rails in place, the intake manifold covers were modified on the bottom. The covers will later be bolted in place using the Mopar gaskets and stainless hardware.
Standard cross-ram throttle...
Standard cross-ram throttle linkage is modified for the throttle bodies, and is compatible with standard Mopar throttle cables.
Looking like a factory cross-ram,...
Looking like a factory cross-ram, this intake is clearly a master of disguise. As a unit, it will simply bolt in place and plug into the EFI wiring harness. When installed, improved drivability, reliability, and economy will be dead giveaways that this cross-ram is port injected, not carbureted.
Dual four-barrel throttle...
Dual four-barrel throttle bodies are used to top this system, but only the passenger side has a Throttle Position Sensor (TPS) that's connected to the EFI computer.
From this angle (passenger...
From this angle (passenger side), you can clearly see all the fuel injection provisions exit at the rear of the intake. Once in a car with air cleaners installed, this system is virtually invisible to all but the well-trained eye.
