Fuel has, is, and always will be the most limiting factor of any direct injection platform. Some OEM’s have resorted to using a combination of direct injection (DI) and port injection (PI) in order to meet the demands of higher horsepower. Most people resort to using water/methanol injection systems which can be un-reliable, inaccurate, and costly to refill on a regular basis. For those looking to push their car past 350whp with a reliable fueling solution then this kit is for you.
Our fueling kit is designed to work with the stock intake manifold and includes an injector boss that has been fitted with injectors in each individual runner. By using a standard fuel injector, you are able to precisely inject an exact amount of fuel as opposed to a W/M injection kit which just sprays pressurized water through a fixed orifice. Included in the kit is an Auxillary Injector Controller which provides you with a 3D table in which you can reference MAP voltage (Boost Pressure) and RPM in order to inject fuel exactly when you need it.
The stock fuel pump is good for up to ~600-620 WHP on E50 which we have tested and confirmed countless amounts of times on our builds. If you are looking to push your engine beyond ~600 WHP you will need to purchase our Surge Tank Port Injection System which includes a much larger LPFP and is capable of supporting 750+ WHP in fuel flow on FULL E85. Please contact us at sales@speedperf6rmanc3.com to inquire for this system as we only build them on a case by case basis.
This kit also includes 4 Bosch high impedance 630cc injector’s. These are not modified 300cc injectors that flow 630cc’s, but actual factory Bosch 630cc injectors. They have a 30 degree cone shaped spray pattern which provides instant atomization as the fuel exits the tip of the injector. If your trying to make more than 650whp on a 50/50 e85 or more mixture, please choose the 1000cc injector option. If you have any questions please contact us before ordering.
Our kit also comes with 4 bungs for meth nozzles on the bottom of the spacer to allow you to run both water/methanol for octane/cooling and the additional injectors for added fueling. If you dont want to ultilize this at all or right away, we include 4 plugs for these holes as well.
We added a Plug-N-Play harness option for the coil packs so that you dont have to cut and splice your coil pack harness to wire in the Aux Injector Controller for an RPM Signal. Just plug in the harness to all 4 coil packs and then plug the controller into the harness and thats it! This is only available with our kit and each Aux Injector Controller is specifically made for us to accommodate this.
There has been much debate about the type of hose to use for applications that require resistance to corrosive fuel such as ethanol, methanol, and certain types of race gas. Our kit utilizes a synthetic rubber hose from Aeroquip that has a rating of “excellent” which means that ethanol has little to no effect on the degradation of this hose. Most other manufacturers will tell you their hose is “compatible” with ethanol but should be checked regularly for signs of wear. You can be sure that we went the extra mile to bring you a product that will last for years to come.
