I'm afraid to blow the motor at my power level so I'm taking precautions by running Torco in the tank, topping the meth and rarely running the car hard but once a week maybe...

BUT, I keep seeing these E85 cars living at well above my HP (720+) for a while now and now I'm seriously considering that route.

I know its a gamble when we do what were doing, but I've spent a lot of time, money and stress so far and want to enjoy the power without the buzzkill of anxiety lol.

I'd love to hear from those that have switched to ethanol and what your experience and opinions are.

I would be much more worried about methanol than any E85 setup out there. Once you start spraying a ton of methanol the cylinder distribution starts to get really unequal....good way to blow your motor. AFAIK Doug @ ECS is the only one to actually hook up individual sensors and explore that on this platform but it's widely documented outside the LSx community.

No cons of E85 other than the cost of a fuel system to support it and making sure you actually are getting E85. States like Arizona only get E51

Was 780rwhp on pump/meth now 933rwhp on e85/meth. May have some new numbers in a day or two.

E85 and meth is definitely a must at that power level. What the limit is on a stock bottom end is hard to quantify. From personal experience, mine didn't last long at 900whp.

Dimewise

many suggestions of which vendor E85 kit to use?

Dimewise

Stock bottom end?

Dimewise

were you on e85 when it broke? And if so for how long and how often did you run it hard?

NeedaC6

Yes, on E85/meth and lasted for 1k miles. I ran it hard a handful of times, can't really say how many exactly, but not every time I drove it.

It did let go (wrist pin gave up, snapped rod) on a WOT run. My car is a 2013 dry sump and had milled stock heads (over 11:1 compression) and a LG G6X3 cam.

Detoxx03

Yep

My car has had over 800 whp for 3 years, over 900 for 2, and over 950 whp for 1. Stock bottom end LS6

Dimewise

Good info y'all. Just to specify, I'm running a wet sump ls3.

Ant-Man

I'll let you know, finished a flex/meth sbe ls2 build should be around ~900 if it doesn't pop.

E85 is awesome. Do it. DSX makes a kit that connects to the factory line/rails very easily but if you aren't running those then I'd just buy a flex fuel sensor and some fittings and plumb it in. You can find the pin # on the ECM via google easy enough

I don't really know what I'm making and I doubt I'm THAT high, but with a 3.25" pulley on a base ECS kit, long tubes, meth, E85, blah blah blah it should be doing pretty well.

Dimewise

interesting, so you're spraying meth while running E85?

why is it a lot of people in the 750+ range are E85 only and no meth?

darkknight91

I'm making close to 700whp on boost only no cam or heads on E85. Keep up with all the oil changes every like 2500 miles, its my daily driver even though i work like 1.5 miles away from my work..

I'm looking to spray a 125 shot on top for third and fourth.. should put me at 800 or so at least.

Cause you don't need meth on e85 nor a flex fuel kit if you know you best use only e85.

No reason to add a flex fuel kit if you can't run gas so why spend the money or have that extra mess there.

What I do have and recommend is an e85 test kit Have 5 gas sta withing a 3/4 mile from my house with e85 I tested only two so far, one has consistent e84 the other tested the same 3 times -e90 the engine loves it sounds noticeably better and crisper too.

so I guess if he gets a batch of E60, I guess he will need to tow it and get it retuned before he drives it?

schpenxel

yeah I'm running both.. I already had the meth kit from before I had a fuel system that would handle E85 so I just left it on when I did flex fuel. Also helps with octane in case I'm not running E85 and I don't think cooling things down some will ever hurt anything so I just left it on

I know someone that ran 18-19psi on straight E85 and drove the absolute **** out of it, stock LS3 and it survived.. no meth, so I don't think it's a necessity if you're running E85 all the time. Just my opinion.

schpenxel

Just run a sensor and you don't have to test anything. Tune can compensate. Also can display alcohol % with dash logic right on the HUD or DIC if you want (won't work on 2005's but will for years after that)

I have not found anything like it, were is the batch e60 and why go there and if and when you find it just call local authorities number to report it is listed on the gas pump, but fyi if you have a wide band you will know cause will read reach.

I'm yet to find a single time I felt the flex fuel kit was needed.
