I'm not really as active on the forum as I have been in the past, but I thought I'd pop on and show everyone what I've been up to with my car and let you know about another potential fuel system coming out for the EB.
I have been running a TB aux system since my car was finished in January. As I've followed various other builds, the writing was on the wall as far as running high power and E85 on TB injection. You have to put so much fuel through the system that you don't get good distribution. This led me to check what options were out there for other Aux systems. I wasn't thrilled with any of the off the shelf port injection kits due to the way the injectors are placed. It's not ideal to have fuel injected into only one runner and that's how all the current setups are run. During my search I started looking into what the Focus ST guys are doing and that's when I ran across the Speed Perf6rmanc3 port injection kit.
Speed Perf6rmanc3 has quite the reputation in the Mazdaspeed world and has also been pretty active in the Focus ST community. They haven't really done much with the Mustang EB yet, but I figured I'd reach out to them and see if their Focus kit would work on the Mustang.
I only needed the spacer and fuel rail because I decided to reuse the fuel lines and Split Second controller from my original Aux kit. I inquired with the guys over there about just purchasing those parts and we worked out a deal for me to test fit everything on the Mustang.
They also sent over their plug and play coil harness for me to test. This simplifies installation of the Split Second because you don't need to cut into your coil harness. The harness fits well and has plenty of slack for you to be able to mount your controller. But lets move on to some pictures and then I'll wrap things up.
Here is everything that I received from Speed Perf6rmanc3. You have the spacer, fuel rail, and the coil pack harness as well. In the Focus ST kit the fuel injectors, Split Second controller, fuel lines, and fittings are also included. I'm reusing everything from my previous Aux kit, and bought new ASNU 1050cc injectors used for R35 GTRs.
Here you can see that the injectors sit in the middle of the runner and are angled to fire down at the valves and not just perpendicular to the airflow.
Here is another nice feature. If you don't have access to race gas or E85 the spacer has ports on the bottom for water/meth injection. The could also be used for direct port nitrous as well.
Sorry this next pic came out blurry, I didn't notice until later. But here I have the plate installed. The longer studs to mount the plate were included as well. You'll notice the sensor on the right that normally runs to the front of the manifold. The bracket that is mounted to interferes with the fuel rail when installed so I had to remount it.
Here's what I did to remount that sensor. Removed the bracket and put a little piece of rubber on the manifold, then used the stock bolt to secure the sensor where the bracket used to attach.
Quick overview of the whole engine bay just after I finished.
Closer look at the rail. I've hidden the wiring under the factory harness as well as I could. Could always go back and use some harness tape to make it look factory.
So there's a quick overview of my new fuel system. I made the necessary adjustments to my 93 octane maps for my Tune+ and FFTEC tunes and the car runs happily on both. I still need a more reliable supply of E85 to really turn things up, there are only two stations within an hour of my house and they both constantly run out.
Let me know if you guys have any questions. Things I can't answer: When will a kit be available, how much it will cost, etc. SpeedPerf6manc3 isn't a vendor on here yet, but I'm sure when they get ready to release something they'll be here. In the meantime you can look them up on Google and you'll get a good idea of what to expect by looking at their Focus ST kit. Anyway, more options coming and we all like options.
