My first FI build.

[Bob Lob Law]

As the title says, this is my first FI build. Been in and around many, but, my first to own. Gonna update this thread moving forward with all mods.
The parts have started arriving. So far, the ESS kit, UPR dual catch can, plugs and thermostat have arrived with 2 more packages expected today.

I went with a G2/G3 refurbished kit. Ordered Saturday night and arrived today.

What’s the end goal for power? Will you be switching to a return fuel system?

 

[SheepDog]

@Bob Lob Law , Don't bother with a return Fuel system. Go with @engineermike 's solution, or wait for the Kit that @Wengerd Performance is working on which is similar.

Goal for now is just a fast fun street car(somewhat reliable) for a daily. Shooting for 600whp on 91 to start with room to grow a little on a 93 only tune and pully. In a couple of years I'll make it a toy and put a fuel system on it as E85 is everywhere around here. Using a BAP for now, but, will probably go with a fuel system like EngineerMike, Wengerd or a KPM. I'm not going to be doing a return fuel system. I think that 600-680whp will hold me over for a while. I was trying to explain it to the wife last night that I'm looking for a lot more acceleration, more like my old ZX14. That this stage is NOT it! But, the E85 stage is getting closer.

The ESS will be very reliable for a daily. You will love it. I love mine. Although I do love it a bit more with e85.
Your power goals, 91/93 - just need a BAP.

Have you thought about keeping the IMRCs or locking them out?
Are you installing this yourself?
A bunch of us have the ESS kit in here so dont hesitate to ask us stuff.

Keeping the IMRCs for now. Car is stock A10 3.55 except for a H pipe, wheels and tires and tint. A buddy and I are installing it in his shop on a lift. I will be driving this everyday rain, ice, snow or shine. Already warming the wife to the idea that I'll be getting at least a second set of rear wheels for stickier tires. I'm kind of bummed about giving up acc to be honest! LOL

Nice! The install is very easy.

Not to hijack the thread but what kit is wengerd working on?

From what I gather it’s a dual fpdm setup sourced from Lawn Racimg, using either a gt500 bucket or radium, not sure on that. But his dual fpdm setup has some shortcomings. And both of the buckets have their own problems as well. Basically every aftermarket fuel system has some serious flaws except the one I built but no one seems to be interested in manufacturing or marketing it.

What does yours consist of?

 

[engineermike]

What does yours consist of?

• Gt500 bucket, modified venturi
• Oem Gt500 filter, under-hood mount, plug-n-play
• Dual FPDM, FPM integrator circuit, plug-n-play
• Custom tuning
  • Gt500 Feedforward table
  • System voltage boost during high fuel demand
  • Engine protection when fuel system limits are reached
  • Tightened limits to trigger P008a fault

This system will support roughly 1100 crank hp on e85, maximizes the use of oem components, full PWM pressure control complete with PID closed loop and KAM learning, oem filter, full oem diagnostics of both FPDMs and pumps, and achieves 600+ lph of bucket-filling rate even when the fuel level is very low. Plus if you do hit the limit of any part of the fuel system (or even run out of fuel) it will modulate the throttle to achieved desired a/f ratio.

I thought KPM was on the right track with their own bucket and venturi design? (Aren't the Dark Horse Track Attack cars switching to their system?) Wengerd seems to be addressing capacity concerns with his pending system but I don't see any bucket/venturi improvements for people experiencing starvation issues during high-g force left turns? Can't trust my recalled OEM pump, especially with no disclosed solution ford is willing to divulge, for even street use so I'm planning to upgrade my fuel sytstem (thanks EngineerMike for your contributions) this winter for road course and possible ESS power-adder using E85 fuel. Looking forward to following this thread.

So how much are you selling your kit for? im sure we can organize a group kickstarter

KPM is definitely my top choice if a) I didn't do what I did and b) a good ole BAP/DW400 isn't enough. However, they still don't have a filter setup...though you can easily use my design. Also, the KPM1500 is reasonably priced but also just runs both pumps full-on with no PWM/feedback pressure control. Both pumps are full-on all the time and pressure is regulated with an internal relief valve at 80-85 psi. You're back into the fuel heating and wasted energy problem. The next step up is their $3000 system that includes their PWM controller. It adds back the functionality of the stock FPDM but I'm not sure that it does OEM-style diagnostics in the case of a pump or wiring failure. But they do appear to be the only aftermarket option that actually understands how the stock venturi system works and even improved upon it.

Wengerd seems to be addressing capacity concerns with his pending system but I don't see any bucket/venturi improvements for people experiencing starvation issues during high-g force left turns?

I've been told he's using the Radium bucket or the GT500 bucket. If it's the Radium bucket, it has a filling issue. The Radium bucket only uses a venturi to draw fuel from the passenger's side, but relies on gravity to get fuel in from the driver's side. Gravity, of course, can't do much if the tank level is low, and certainly can't keep up with a high demand over 400 lph. The GT500 bucket, stock could be worse. The GT500 bucket venturi system is different from GT so you have to remove the venturi nozzle and drill out a venturi hole for it to even partially work. Otherwise, it has no way to pull fuel over from the passenger's side.

The guy who designed the FPM integrator and dual-FPDM harness doesn't want to make harnesses. We contacted 3 aftermarket companies, and none have shown interest in buying just the FPM integrator to build into harnesses.

The second issue is the venturi modifications. It's best to start with a gen3 bucket bottom, enlarge some existing holes, and snap onto the GT500 assembly. This means we would need sacrificial gen3 buckets or the end-user would have to drill some very specific and tiny holes in their old venturi and install themselves. Not ideal either way.

Thirdly is the tuning...I'm not really interested in getting into the tuning business but the above WILL NOT work without tuning. And basically none of the commercial tuners seem to want to associate with anything I touch. I have worked with DRP Motorsports on some stuff and we could probably come up with an arrangement, but you'd most likely have to switch to his entire tune even if you're happy with what you have.
