Radium Engineering Releases Port Fuel Injection Kit for the Ford EcoBoost Engines


EcoBoost power is no longer limited by the direct injection system!


Radium Engineering has released a port fuel injection kit for the Ford Focus ST, Focus RS and Mustang 4-cylinder EcoBoost engines. This kit supplements the direction injection system, allowing more fuel to be fed to the engine and more power to be created.





Radium's Port Injection Kit (PIK) is comprised of two main components, the spacer plate and the fuel rail. Each of these components is CNC machined from aluminum and anodized for an attractive finish that resists E85.

The 25mm thick spacer plate is precisely designed to not interrupt the air flow as it transitions from the intake manifold runners to the intake ports. The passages in the spacer plate (shown in green) are carefully machined to port match the intake port and the intake manifold, eliminating any air flow disruptions. A 'knife-edged" port divider is also machined into the spacer plate, improving on the blunt divider machined in the cylinder head.



The spacer plate features fuel injector ports that are strategically located and angled to ensure the best fuel delivery into the intake ports.

The other critical component of the PIK is the fuel rail. Radium Engineering specializes in fuel rail design and created this custom one specifically for this application. Like other Radium fuel rails, this one features a large internal bore and is threaded at each end for -8AN ORB. Phenolic mounting spacers provide insulation from heat conduction. The fuel rail is compatible with common "34mm" aftermarket injectors with 14mm upper and lower O-rings.



The PIK installs next to the valve cover as shown and does not disrupt the surrounding components.



The port injection kit includes all the hardware and pieces shown above. The green brackets are used to relocate the mounting brackets for the plastic engine cover, allowing it to be reused.
Injectors, plumbing and fittings sold separately.

MSRP: $379.95

Neat. Would be nice to see another article showing it in use.

Thats one way around GDI limitations... I'm assuming this requires a standalone ecu to run? or are some of the reflashing software capable of running this?

You can run a piggy back or extra injector controller. Typically in these situations you are just adding a given amount of fuel to compensate for a lack of fueling in certain high loads. WOT at full boost where you may run lean on just the GDI, adding 10-20% fuel will just bring the lambdas back into target. in lower boost levels where fueling may not be an issue secondaries wont be necessary. if you staged in the secondaries where fueling is not an issue, the factory ecu will want to trim the lambdas back which will result in poor fuel trims and more issues.

It gets really trick when having dual ecus control the engine, keeping the secondary controller as simple and trouble free as possible keeps the primary ecu from having to fight or try to account for inconsistencies in the secondaries.
