Boomba Racing's Auxiliary Fuel Rail System - Released

[Sirsinclair]

See my edit.

Ah okay. Well that's a bummer.

There is the possibility of making a cam that has four HPFP lobes instead of three but we are let down by the timing belt. If we had a chain, we could do the Focus RS four lobe cam trick without issue.

Hopefully a company with money will try it out and engineer a solution. Maybe we can run a wider timing belt?

The injectors are a separate problem, you really need the OEM to develop an upgrade part but they are busy designing stuff for MY2020 now.

Is there a possibility injectors from another car would work? FoST injectors possibly?

Thanks for sharing this info.

The Focus ST 2.0 and 2.3 use a first generation style direct injector. I think Bosch makes an upgraded injector for that style. It might be the same as the 3.5 injector too. The 1.6 uses the newer style direct injector which flows pretty good but has no upgrade as far as I can tell.

With only the Fiesta ST and Fusion using the 1.6, it might take a while for that upgrade unless they use that style of injector in another engine. If the Nano V6 uses a similar injector (It might), when that Nano powered Fusion comes out it might create a big enough market for upgraded injectors. The 1.6 in the Fusion does not create a market because the people buying a Fusion who want performance would get a 2.0 instead.

It will take a while before the direct injector design become as standardized as port fuel injectors have become. We are probably on the too early side of that.

I'm not sold on "more pressure" being a real solution either honestly, combustion stability with only the stock injectors can get a little hairy sometimes, add meth, and all it well

Sooooo... What's better, this or the DHM option?

Sooooo... What's better, this or the DHM option?

well, there's only one that works right now, so winner is DHM.
also, just an FYI... Russ hinted of a multiport solution in the near future.

Just to make sure our intentions are known with this kit, I’d like to break a couple of things down. This system is going to be as budget and user friendly as possible, with that said we are using only four injectors in four ports, because if you center the injector between the two, there lies less chance for the fuel to flow into the air stream smoothly, because it will be injected directly onto bridge which is an inefficiency in the delivery process. There is no need to have fuel on both valves, this is NOT a primary fueling system; this is a supplementary fueling system (like a water/meth system) that will only need to be used at RPM and boost where the factory HPFP cannot keep up. Next, the reason for using a twin rail system is to utilize a dual feed to create as close to constant pressure on the injectors as possible, to alleviate inconsistencies in fuel delivery, though earlier said already this will be supplementary fuel it is still going to need to be as consistent as the factory fuel system because the factory system will be dependent on this system while in use. We will be selling these systems without the fittings or injectors so you will be able to use your own preference of fitting style to set the unit up how you would like.

The goal here is to allow the end user to build their own set-up at a lesser price than a fully assembled alternative. Plus, ours will allow for a lot more customization.

Where do I sign up for one of these kits and how much? Or if you need a demo car I'm always available. I personally feel this is the best option for auxiliary fueling coming to market at this time. Thanks again for your continued development of our platform.

These will officially be for sale by later today! We appreciate the continued support!

Introducing our Auxiliary Fuel Rail System for the 2014 + Fiesta ST

This auxiliary fuel system is meant to work in conjunction with the OEM fuel system on your car in order to support higher horsepower builds and to assist in the cleaning of your intake valves. This system is based off of our intake manifold spacer [horsepower and torque gains from that] with provision for a dual rail fuel set-up to promote even pressure of fuel. A port injection set-up like this is much safer than a throttle body injector due to the fact that no fuel can pool and ignite in the manifold when spraying directly into the cylinder.

Included is the following:

Intake manifold spacer with four 1/8” NPT ports and four fuel injector ports

Dual fuel rail threaded for AN6 plugs or fittings

Two plugs with o-rings

All necessary mounting hardware

O-rings and receptacles made to accept a 50mm tall injector with a Bosch style plug

The goal here is to allow the end user to build their own set-up that will cater to a variety of set-ups. NOT included in the kit are injectors or a controller.

As always this product is designed and manufactured 100% in-house in the USA.

Available in your choice of color: Onyx Black, Royal Blue, Race Red, or Pure Aluminum

I went back and edited my original posts as I meant to but forgot about doing.

The parts are beautifully made to say the least and will help on fueling I am sure.

I agree one injector per cyl firing into a divider, not a good thing, 8 injectors is the only way I can think of to clean all the valves but that sure raises the cost and complexity but sure much less headache than having 4 dirty valves that have to be cleaned periodically.

Another thing that comes to mind is filling the cylinders evenly with only using one valve out of the two intake valves, not an easy thing to verify but something to consider.

Perhaps there is enough interest in an 8 injector version to make that an option, all the hard work is done, just move some things around, a bit of redesign but with your abilities should be relatively simple. Of course there would have to be injectors small enough to work well with it.

Most sincerely,
Rick

It can be added if someone already has the spacer, correct?

 

[Perfblue15]

Order placed. Thanks again.

Unfortunately not. The machining on these is a lot different to be able to accommodate that injectors and the rail.

There are out now!

I have a jet mill. Lmk what you can sell me the other parts for
