So, no-one's commented on this, so I assume it's not an issue, but is our fuel system fully compatible with E85? The high concentration of ethanol will not cause any seal or other problems down the road?

Yea 40 has big plans for his sky... he wants to turbo swap that thing and run it on E. We are going to be experimenting with fuel pumps and stuff. I am just going to be helping him whenever I can... I have a new project coming up this summer I'm saving for so the balt is going to stay the way it is for now.

But back on topic, E85 is very worth it if it is near you. Withing about 15 minutes for me so its not too big of a deal. It really is worth the PITA to pump/mix fuel twice and the lower fuel economy for the cheaper fuel and more hp because of E85.

Nice thing here is 100 octane is readily available. I've been adding about 2 gallons at every fill up because the premium in Vegas is only 91 octane. Unfortunately the place I get the 100 octane doesn't sale e85 so it would be a bit more of a hassle having to make two stops. But for the power it provides I think I could deal with it! I will have to ponder this a bit more...

Also nice to see there are a few more of us in the western half of the country!

Every fuel system after 2004 (dont recall the year exactly) is compatible with E85. It actually keeps your fuel system cleaner than regular dino fuel. You have to be cautious about one thing though... It is a hydrophilic solution (attracts water) so it shouldn't just sit around.

The problem with our DI fueling is that the injection window is to short to get enough fuel into the cylinder... when you lengthen the injection window fuel rail pressure drops, it's a catch 22 really. We need a better flowing HPFP essentially.

If it's not E85 Flex Fuel compatible from GM it WILL VOID YOUR WARRANTY. And GM can detect it if they send broken fuel components back to GM. The fuel pump guy I've mentioned inspects them for warranty re-imbursement

one thing to consider for people who are worried about voiding their warranty.......

I wonder how they test for this could you maybe get more info? I have never heard of this before and I personally don't care because I'm going to continue running E... It may, however have some effect on someone else's decision.

kennysabarese · « **Reply #59 on:** June 01, 2011, 11:26:33 PM »

I assume they can test the fuel that would be on the parts or can see corrosion from too much E.

The guy I am referring to who works for GM is "JET WS6" on Skyroadster.com if you want to try to contact him.

Ryridesmotox · « **Reply #60 on:** June 01, 2011, 11:43:45 PM »

Ok well I was just wondering cuz I never heard of that before. The new fuel systems are supposed to be fine with E no matter what. The only difference between flex and non flex motors is the computer's ability to recognize the difference between E and normal fuel. I think the reason why they would want to know if you are running E85 is cuz you would want it for performance in these cars which requires tuning... something GM doesn't want you to do.

snaponbob · « **Reply #61 on:** June 02, 2011, 07:50:18 AM »

Oil can be tested, and it WILL have lots of evidence of fuel type.

The kappa fuel system may be perfectly fine. But in the owners manual GM says gasoline only and that's that.

SKY888 · « **Reply #63 on:** June 02, 2011, 01:12:44 PM »

i believe I read somewhere that the lines, seals, etc of these new flex fuel engines were upgraded by GM to be compatible for E85........

need to research about this again.....

Brazen17 · « **Reply #64 on:** June 02, 2011, 01:16:25 PM »

I guess you could always call or email GM and see what they say. Email would be better 'cuz if they say it is ok then you have proof.

SKY888 · « **Reply #65 on:** June 02, 2011, 01:33:06 PM »

customer service of GM....is the worst, unfortunately

I'll be lucky, if I get an email acknowledgement that they received my inquiry.

but I'll try

What about emailing that person on SkyRoadster who works for GM

She posted in someone's thread with a dead car.

At least IF you get a positive response you have proof GM said it was ok to run e85. But, yah, they are sometimes lacking in the customer service department.

SOB received the Walbro pump unit that I sent him.

We'll all soon find out.......if it solves his fuel starvation issues at high rpm.

snaponbob · « **Reply #69 on:** June 02, 2011, 06:57:18 PM »

Yup. Got it. And promptly MOWED 2.5 acres!!

Gonna drive the car as it is tomorrow and see if it cackles at 6K. If so, I'll scan it for Vince, then load an alternative "dry" tune and drive some more to see what happens above 6K. Regardless, the new pump will go in as will the original tune, and we will see how it goes.
