Why E85 is a Great Fuel for Beginners in Racing and Performance Tuning
If you’re new to modifying your car for performance or racing, you’ve probably heard people talking about E85. This fuel blend—made of 85% ethanol and 15% gasoline—isn’t just for pros. It’s a fantastic option for newcomers who want to get more power out of their engines without breaking the bank. Here’s why E85 is worth considering and how you can start using it in your build.
1. E85 Gives You More Power Without Breaking Your Engine
One of the biggest reasons racers love E85 is its high octane rating—around 100 to 105. Octane is what keeps your engine from knocking when you push it hard, like when adding turbochargers or superchargers or running higher compression. With E85, you can tune your engine more aggressively and unlock more horsepower safely.
Even if you’re just starting out, switching to E85 and adjusting your car’s tuning can lead to noticeable performance gains compared to regular gasoline. It’s like giving your car a power boost just by changing what’s in the tank.
2. Keeps Your Engine Cooler
Ethanol-based fuels like E85 have a unique trick up their sleeve: they cool things down. When E85 enters your engine and evaporates, it absorbs heat. This “cooling effect” lowers the temperature of the air-fuel mixture, which leads to denser air and better combustion. In simple terms, cooler air equals more power.
This is particularly helpful if you’re running your car hard at the track, as it reduces the chances of overheating and keeps everything running smoothly.
3. It’s Budget-Friendly for Racing
For new enthusiasts, cost is always a factor. E85 is typically much cheaper than high-octane racing fuels. Sure, it does burn more quickly than gasoline, but the lower price offsets that for most people. You can enjoy the performance benefits of a racing-grade fuel without having to spend hundreds on specialized blends.
Plus, you can find E85 at many regular gas stations (especially in the U.S.), making it more accessible than you might think.
4. It’s Better for the Environment
If you care about reducing your environmental impact while still enjoying racing, E85 is a good choice. Ethanol comes from renewable sources like corn or sugarcane, so it’s more sustainable than traditional gasoline. It also burns cleaner, producing fewer harmful emissions.
For beginner tuners, this means you can feel good about your fuel choice while still having fun with your car.
5. Modifications Needed for E85
Switching to E85 does require a few changes to your car, but don’t worry—they’re manageable even if you’re new to modifying. Ethanol contains less energy than gasoline, so your car needs to burn more of it to get the same power. Here’s what you’ll need:
• Bigger Fuel Injectors: These help deliver the larger amounts of fuel your engine will require.
• Upgraded Fuel Pump: Your stock fuel pump might not be able to keep up with the higher flow rates of E85.
• Tuning Software or ECU Update: To maximize the benefits of E85, you’ll need to adjust your engine’s settings, which is usually done with a tuning program or by visiting a professional tuner.
Many beginners start with “flex-fuel” setups, which allow the car to run on both E85 and regular gasoline. This gives you flexibility while you’re learning and figuring out what works best.
6. A Few Things to Watch Out For
E85 is great, but there are a couple of things to keep in mind:
• Water Absorption: Ethanol absorbs water from the air, which can lead to corrosion in your fuel system if you leave it sitting for a long time. To avoid this, try not to let E85 sit in your tank for months.
• More Frequent Fill-Ups: Since E85 burns faster than gasoline, you’ll need to refuel more often. For daily driving, this might be a minor inconvenience.
How to Get Started with E85
If you’re ready to dive in, here’s a simple roadmap:
1. Research Compatibility: Check if your car’s fuel system can handle ethanol-based fuels. Older vehicles may need additional upgrades to fuel lines and seals to avoid damage.
2. Upgrade Key Components: Invest in larger injectors, a higher-flow fuel pump, and tuning software. These upgrades are common for anyone modifying a car, so you’re learning valuable skills along the way.
3. Find a Trusted Tuner: A professional tuner can help you adjust your car’s ECU for E85. This ensures you’re getting the most power and running safely.
4. Locate E85 Stations: Apps like GasBuddy can help you find nearby stations that sell E85, so you’re never left searching when it’s time to refuel.
Conclusion
E85 is one of the easiest and most affordable ways to boost your car’s performance, making it perfect for newcomers to the racing and tuning world. It offers more power, cooler engine temperatures, and an environmentally friendly edge—all while being budget-friendly. With some basic modifications and a bit of learning, you can transform your car into a more powerful, track-ready machine.
If you’re just starting your journey into performance tuning, E85 is a great fuel to explore. It’s the perfect combination of accessible and high-performance, giving you a competitive edge without overwhelming complexity.
