An aftermarket EFI system with a flex fuel sensor controlling boost, fuel, and timing is where pump E85 shines. Also, they make E85 rated fuel pumps... most of his "cons" are folklore from anti ethanol people.

E85 makes a significant difference with boost rather the NA. It will pick up a little bit with NA, add boost and watch the numbers significantly change.

E85 is so common now and easy to run compared to when this video came out

Really great guys went to places I needed to hear.

The sweet spot for optimum air/fuel ratio is much wider for E85 vs gasoline making tuning easier.

E85 with a flex fuel sensor and a terminatorX. Let the tune compensate for varying E85 content.

Btw, they do make oil you can add to E85 to increase its lubricity and reduce its corrosion. It's also supposed to help upper ring lubrication. They say it's designed to burn so I think it even plays nice with catalytic converters.

I understand these guys don't work with the same engines as we do (forced induction) but here in Australia pump e85 has been a game changer, we thankfully have really reliable ratio's now (didn't used to be) but tbh most tuners will say past 60% ethanol you're not seeing a huge difference so varying mixtures isn't as much of any issue as people like to say. Even back in the day when mixtures changed with the season we weren't having issues. Power, yes, we get a bit more, actually a reasonable amount more but that's not why most of us go it. More importantly the EGT's, cooling and knock resistance when you're more interested in reliability is huge, you can run E85 lean and be way less worried about blowing up an engine, it's just a huge buffer for the tune and improving conditions in the cylinder. You'll struggle to find anyone running a straight Petrol based fuel at any Drift event in Australia, and same goes for club level track stuff, roll racing etc. Basically unless you're getting it in a drum, anyone that takes motorsport half serious but still wants to just go to the pump is running E85.

Once again, never go against Brule lol

DrivingforAnswers explains the math on why e85 makes more power. It has less energy per gallon but you use more gallons. It turns out the more fuel used adds up to more energy going through the engine at the same air fuel ratio.

In the name of testing, don't forget to try LESS ignition timing. You might be surprised

i have ran e-85 for years. never had any water or corrosion issues. i also leave it in all winter.

Well Freiburger, you can anodize your intake and inside your intake port after it gets polished. Those E85 carburetors look like they have some kind of anodized surface for the E85. I don’t know about the exhaust side, if it needs anodizing.

Boost would have made more of a difference not to mention lower air charge temps, lower cost and more octane than PUMP gas, not race gas.😮

I love the smell of pump e85 its sort of pleasant and wonderful smelling compared to gasoline.

E85 here in utah isn't E85. Idk how they come up with this shit. Its what happens when companies are allowed to subvert their customers

Ethanol will increase VE up until about E40 in an NA application. After that, VE falls off compared to gasoline

Does your air fuel ratio bounce around about 3 numbers when it idles on a wide band o2? My 427 small chevy with e85 and a gross 680 lift big duration camshaft bounces around at idle? Trying to get it dialed in any ideas?
EricSerbouski
Is it just me or does Brule only make wisecracks towards Dulcich, never Freiburger?

E85 isn't displacing air like that, otherwise we'd see a power loss across the board. I think it's performing better down low and in the mid RPMs because we're carbureted and E85 takes more fuel to burn stoich. Vaporizing that added fuel further reduces the intake charge temperature allowing denser air into the engine. That's where the extra torque and power is coming from. This effect falls off at higher RPMs because the fuel has less time to vaporize before getting sucked into the engine.
