Well while tuning the car on E85 with an FP RED, ID 1000s and a single modded Walbro, I am at 98% IDC at 24 psi, and the injectors go static at 25 PSI.

I need to figure out what I need to do to get the fuel under control...

I am looking at the High-Z FIC 1100s, but don't know if that is going to get me to where I need as they only flow 20% more than the ID1000s...

I know the injectors are maxed out, but don't know how close I am to maxing out the fuel pump... VDR says I am at 445 hp dynojet settings...

So I need experienced no crap answers on what I can do, in the cheapest way to get the fuel under control and actually use the FP Red at around 27-28 PSI on E85.

Option 1- Purchase the FIC 1100s (will they be enough with a single walbro with fuel pump wiring kit/relay?)
Option 2- Purchase the FIC 2150s (will they be enough with a single walbro with fuel pump wiring kit/relay?)
Option 3- Purchase a double pumper and Low-z injectors (more than I am looking to spend and I like the High-z injectors)
Option 4- Purchase an inline walbro and Low-z injectors (doable but I love the High-z injectors)
Option 5- Purchase a double pumper and FIC 2150s (ballin)
Option 6- Purchse an inline and FIC 2150s (still money)

 

you still running stock base FP? You can run decently high fuel pressure. Me personally would i would still be looking for a second pump. either internal or external. What about getting a second pump and raising your fp?

 

The FIC and ID injectors are the same. They just have different naming conventions.

I would start with bumping up your base fuel pressure. You should bump it to 50psi and see if that gives you the head room, if not go to 60psi. Just make sure you do not go byond the limits of the Fuel pressure regulator. Most are rated from 0-100psi. So you should be able to run a base of 60psi with out a problem.

I woudl also just do the double pumper, and call it good.

 

Option 7- Purchase an inline and High-Z FIC 1100s (still money)... I'd consider an aftermarket FPR as well.

Here's what I did... didn't have much luck with the double pumper setup the first go around. Don't think you need to go this elaborate, but for the $$$ an inline vs double pumper is pretty close.

Might want to consider a Bosch 044 Universal Inline Fuel Pump. These usually go for less than $200. AMS has a pretty good "In Line Fuel Pump Instruction Guide" that you could tailor accordingly for your budget. Also, I would not recommend using the stock fuel return line. IMO it is too small for both an in line and double pumper set up. You'll run into back pressure issues.

Charlie, yeah I am still stock base FP... I would have to buy an external FPR and install kit...

The FIC 1100s are a different injector than the ID1000s/FIC900s... again, I am going for the frugal solution, and don't want to do anything else power wise to the car, I just wanna run E85...

 

I've dialed in both the ID1000s and the FIC1100s on my Evo. The FIC1100s scale 21% higher than the ID1000s, so they give you your 20%. Doubt a single Wally is going to be able to feed them to 100% duty though.

 

I have no clue then... my buddy Cary's car has most of the same mods as me except an FP black and he has FIC 1050s (low-z) he is at 85% IDC at 25 psi (single unmodded Walbro) and about 500 hp on Dynojet VDR on E85 that is why I am asking...

Mychailo what IDC are you seeing at your HP level?

 

Bryan's dyno posts indicate that a single Wally can sustain no more than 440 whp on his Mustang Dyno. That corresponds to about 500 DJ whp. If that's all you want, you should be able to get there on a single Wally.

 

Thanks for the info, I was actually searching through his posts when you posted that!

 

Bryan's dyno data has been great for figuring out fueling for E85. With my FIC1100s, I'm hitting about 73-75% IDC at about 360 GST-MD whp based on the VDR calibration (70F weather).

 

Do me a favor, can you run the log through VDR dynojet, with the following... so I can get an idea... I know it is not very scientific, but for IDC calcs it will be close, Thanks

wheels- 255-35-18
2005 5 speed
vehicle weight 3260
driver 180
dynojet average

 

All the vehicle and weight parameters are vehicle specific, so I shouldn't be using yours. If I use the DJ average on VDR, I get 396 whp in 70 F weather. I'm about to roll on ER's dyno, and will post that up this evening.

 

I can tell you from real life with the same combo you are now at 456/356 at 24.5psi +/- That was with 102-104% IDC and not going static (as in zero fuel control) at that level. Single Walbro/1100s/unknown fuel filter life/just switched to E85 today.

Correct Aaron, pretty much exactly the same... my injectors went static at 107% IDC at 25.5 psi...

And from our textversation last night, looks as if the FIC 1100 (high-z) have pretty much the same characteristics...

 

I hit 410 whp on ER's dyno, 73% IDC (thanks Aaron for your time!) with my FIC1100s. 100% duty should be enough for 560 whp on ER's dyno if the fuel pump can sustain the pressure/flow.
