Hi guys,

I have an FP Red turbo about to go on my car and I plan on giving it the juice it needs to be happy..E-85. I'm new to the E-85 scene, read through a bunch of E-85 threads and have many questions if you guys could help answer...

1. For a turbo like the FP Red, would 1200CC injectors be the ideal size injector for running E-85? I will be running lots of boost. Should I upgrade my fuel rail or is the stocker good enough?

2. Should I get Dual Walbro fuel pumps or would one suffice? I already have one Walbro... can I just buy & add a second or is additional hardware required?

3. I'll be running this on stock ECU and all the other supporting mods... this car is my year-round daily driver here in NY. For those of you that live far away from a good tuner and are not good at solving problems with your car... what do you do and where do you take your car when it breaks down? How are the cold starts with E-85? Any freezing issues?

4. Corrosion. I've seen on the news before and have been told that running E-85 in cars not specifically designed for E-85 can accelerate corrosion. Others have said that it doesnt if you change some parts. Is there a definitive answer to this and does this concern you guys?

5. One topic not often discussed enough is passing car inspection... I live in New York where they hook your car up to a sniffer and plug into the car... If I am running E-85 with the huge injectors do I stand any chance in hell of passing inspection? What do you guys do to get around inspection in states that are tough on emissions?

6. Notice I didnt ask any "How many ****** powers do you think my car will be?" questions

I'm sure some of these questions have been asked before.. I did some searches but the search engine on these forums isnt top notch. I'd like to have all these noobish questions answered in one thread for dummy's like me

Thanks for any help guys.

 

I too want to hear some of those answers.....suscribed

 

****** power... LOL

 

4. No one has ran E85 long enough to know the long term affects on the Evo. I think 1 guy on here has ran it for 2 years and no problems. I've personally ran it for 8 months and no problems and my tuner has ran it for 1.5 years and no problems. Since E85 releases a lot of water vapor, my exhaust components could rust out faster...

5. I've passed CA emissions on E85 using 660cc injectors, but i am now running 1000cc's, but i haven't done an emissions test with the 1000's. Note, do not tell the emissions guy you're running E85 since its technically illegal to do E85 conversions per the EPA.

 

I have ran it for two years over 25,000 miles in my IX and no issues so far. Haven't even needed to change the spark plugs.

I have also ran E85 in my Talon for almost 4 years and have not had to replace anything.

Many turbo/supercharged cars around Minnesota have been running e85 with zero effects. I have yet to see one issue with E85 from the local car clubs around here.


We don't have inspections or emissions testing here in Minnesota.

 

Thats something I'm surious about... Do I need to run a specific type of plug? How often do people running E-85 check and/or change their plugs?

 

FIC1050s would be enough for a Red. Not sure about RC1000s. Might need the next size up offered by RC.

Most everyone is using the stock fuel rail. It actually have a very large cross section, ... larger than most aftermarket fuel rails. Some might say that the strongly rectangular cross section of the stock rail is not the best for flow though.

 

Its all relative to the amount of power you want to make.

480whp on E85 is about the limit for 1200s and a single pump

506+ is possible with duals.

Above that are 1600's and I dont see them being for everyone. Mine have intermittent drivability issues and realistically need a second pump to work right since the seem to aggravate fuel pressure drop at higher boost level.

 

My setup is close to what you are looking at...

I'm going to be running E85, I chose 1200cc injectors with dual pumps so I don't believe fuel will be an issue with my goal of 30 psi on the Red. I've heard that one walbro on E-85 tops out at about 400 -450 max.

As for your *****'s power... that's going to depend on your supporting mods but I'd guess no less than 450, but a guess isn't worth anything at this point

 

good questions...subscribed...

 

After doing some more research it seems like 30PSI on E-85 with 1200CC Injectors and dual Walbro's is ideal for an FR Red on a stock block.

My questions that are still unanswered...

If I already have a Walbro installed, can I just buy another to run a dual setup or is additional hardware required?

Corrosion? Cold startup problems? If not living near the shop who installed/tuned your car... who do you go to to have work done on the car if it breaks down?

Anyone have trouble/workaround with passing inspection in strict emission states while on big injectors & E-85?

 

DB Performance has run e85 on a single Walbro up to 450-460whp safely in their experience in DSMs, thats on a DynoDynamics dyno too which reads real low. But every setup is different so its tough to know for sure. I would try a single pump first and see where it gets you.

Their daily driver E85 4g63 runs on a signle walbro 255 and it makes 480whp on a 61mm turbo.

Again, not Evos but somewhat similar. I'm going to try for mid 400's on a single pump.

 

I was watching lucas' IDC on 1200's and duals last night and it was exactly at 80% on E98 (figure 5% less on E85) and this is making 506+whp. In these type of situations I almost think motor type is immaterial when dealing with fuel requirement to fuel vs. power.

Quick recap-

1200's and single made 440whp at 83% IDC on E85
1200's and dual makes 506+ at 80% on E98 (about 73-75% if it where E85)

 

You will need additional hardware. Buschur offers a core exchange with the stock unit, and Full Blown offers a completely new setup.

My car starts on the first try in the winter, but I usually have to hold the revs for a few seconds before the idle steadies out. I have been running E85 for about a year without any troubles from corrosion.

Fortunately, I only have to worry about OBD-2 inspection. I don't know about the whole tail pipe sniffer.

 

Does Lucas use the Full Blown unit or something else? Is Lucas still using the OEM ECU?
