E85 Flex Fuel: Power Boost For Your Ride?

E85 flex fuel is known for being more eco-friendly than regular gasoline, but it can also increase your engine’s power. If your engine is tuned right, it can gain up to 20% with flex fuel. E85 is popular in racing because the engine runs cooler with E85 than with gasoline. However, a stock Toyota Camry won't see any performance benefits from running flex fuel.

E85 fuel has a faster ignition time and flame propagation when compared to gasoline

The vehicle ECU used together with eFlexFuel does not need to retard ignition or lower the boost pressure in any circumstances. This means more performance – just when you need it.

E85 is popular in racing because the engine runs cooler with E85 than with gasoline. Ethanol has a cooling effect in an engine due to its high latent heat of vaporisation. This means that ethanol absorbs more heat from its surroundings when it changes from a liquid to a gas compared to petrol. When E85 fuel is injected into the combustion chamber, the ethanol absorbs a significant amount of heat as it vaporises, effectively lowering the intake air temperature.

E85 fuel can actually clean the engine for you. Ethanol is an effective cleaner that can remove deposits in the fuel injectors and throughout the cylinder head.

The higher ethanol content makes E85 more volatile and allows it to evaporate faster than petrol. This can increase the risk of vapour buildup, especially in confined spaces, making it crucial to handle E85 in well-ventilated areas. While the flash point of ethanol is lower than that of petrol, (meaning it can ignite at lower temperatures), it is also more conductive than petrol, which can pose a risk of static electricity build-up during fueling operations. To ensure safety, handle E85 away from open flames, sparks, or sources of ignition. In case of spills, clean them up immediately using absorbent materials and dispose of them according to local regulations.

E85 is up to 85% ethanol, which increases the engine's power by up to 20%

E85 is up to 85% ethanol, which increases the engines power by up to 20%. This is because E85 has a faster ignition time and flame propagation when compared to gasoline. This leads to higher cylinder pressure, as well as increased engine torque and power. The increased exhaust gas flow allows turbos to spool quicker.

Alcohol is effective in creating more power because it offers high octane content. E85 is the highest octane fuel on the market.

Professional racers prefer alcohol-based fuel because the engine runs cooler with E85 than with gasoline.

Alcohol has been used in drag racing, NASCAR, IRL, and so on.

Simply switching to E85 flex fuel won’t instantly increase your engine’s horsepower. Your engine needs to be tuned right to gain the benefits of flex fuel.

E85 flex fuel is known for being more eco-friendly than regular gasoline. There’s another benefit of flex fuel that only a few people know about. It can increase your engine’s power! If your engine is tuned right, it can gain up to 20% with flex fuel. Here’s why: There’s a reason professional racers prefer alcohol-based fuel. For decades, alcohol has been used in drag racing, NASCAR, IRL, and so on. Alcohol is effective in creating more power because it offers high octane content. E85 is up to 85% ethanol, aka ethyl alcohol. So naturally, E85’s high alcohol content makes it the highest octane fuel on the market.

Your engine needs: Our eFlexPlus or eFlexPro kits help you achieve both goals in the easiest way possible. All you need to do is install one of our kits and then select an engine tune that will increase your engine’s power up to 20%.

Octane number represents the resistance of a spark ignition engine to knock (unwanted detonation which can damage the engine). The high intrinsic octane numbers of ethanol and methanol are well known. However, a much greater effective octane number can be effectively realized through the knock resistance provided by the high level of vaporization.

One advantage shared by the four major alcohol fuels is their high octane rating. This tends to increase their fuel efficiency and largely offsets the lower energy density of vehicular alcohol fuels (as compared to petrol/gasoline and diesel fuels), thus resulting in comparable "fuel economy" in terms of distance per volume metrics, such as kilometers per liter, or miles per gallon.

E85 is popular in racing because the engine runs cooler with E85 than with gasoline

E85 is a fuel that is made of 85% ethanol and 15% gasoline. Ethanol has over 1/3rd of oxygen by mass, which is higher than in oxygenated race fuels, where the levels are below 15% of oxygen by mass. When oxygen is introduced as part of the fuel to the engine; the heat energy is used to change the state of fuel from liquid to gas. Alcohol has nearly ten times the cooling effect when comparing to gasoline. Cooler temperatures mean there's less risk of heat build-up in the motor. Heat build-up can cause all kinds of problems in racing: everything from reduced power output to engine failure.

E85 is a specialized fuel that boosts huge power to the engine? It’s popular because the cost is a fraction compared to commercial race fuels. Non-toxic ethanol cuts greenhouse emissions by almost 59%. E85 has a lot of the cooling properties that you also find with Water Meth Injection. It is great at lowering intake temperatures, lowering engine block and head temperatures, and basically doing everything that can help suppress detonation.
