How Much Power Does the Fueltech E85 System Gain You? Real Dyno Results

by

The FuelTech E85 system has gained popularity among automotive enthusiasts and tuners alike, primarily due to its potential for increased power output. This article delves into the real dyno results of vehicles equipped with the FuelTech E85 system, exploring how much power can actually be gained.

Understanding E85 Fuel

E85 is a blend of 85% ethanol and 15% gasoline. It has a higher octane rating compared to regular gasoline, which allows for more aggressive tuning and potentially higher power outputs. Here are some key characteristics of E85 fuel:

  • Higher Octane Rating: Typically around 105-110, which reduces the chances of knock.
  • Increased Cooling Properties: Ethanol has a higher latent heat of vaporization, which can help cool the intake charge.
  • Environmental Benefits: E85 produces fewer greenhouse gases compared to traditional gasoline.

The FuelTech E85 System Explained

The FuelTech E85 system is designed to optimize engine performance while running on E85 fuel. It includes a range of components and features that enhance tuning capabilities, such as:

  • Advanced Tuning Software: Allows for precise adjustments to fuel maps and ignition timing.
  • Flex Fuel Sensor: Detects the ethanol content in real-time, enabling automatic tuning adjustments.
  • High-Performance Injectors: Designed to deliver the necessary fuel volume for high power applications.

Real Dyno Results: Power Gains

To understand the actual power gains from the FuelTech E85 system, we analyzed several dyno tests conducted on different vehicles. The results varied based on engine setup and tuning, but common trends emerged:

  • Turbocharged Engines: Many turbocharged setups saw gains of 50-100 horsepower when switching to E85.
  • NA (Naturally Aspirated) Engines: Typically experienced gains of around 20-40 horsepower.
  • Overall Torque Increase: Torque also increased significantly, often by 10-20% across various setups.

Factors Influencing Power Gains

Several factors can influence the amount of power gained from the FuelTech E85 system. These include:

  • Engine Modifications: Heavily modified engines tend to benefit more from E85 due to higher boost levels.
  • Tuning Quality: The expertise of the tuner plays a critical role in achieving optimal power gains.
  • Fuel Quality: The quality and consistency of the E85 fuel can impact performance results.

Case Studies: Vehicle Performance

Here are some specific case studies highlighting the performance of vehicles using the FuelTech E85 system:

  • Case Study 1: A 2015 Ford Mustang GT equipped with a supercharger gained 85 horsepower and 70 lb-ft of torque after switching to E85.
  • Case Study 2: A 2010 Chevrolet Camaro SS with a stock engine saw a 40 horsepower increase on the dyno.
  • Case Study 3: A turbocharged Subaru WRX STI reported gains of 95 horsepower after tuning for E85.

Conclusion: Is the FuelTech E85 System Worth It?

In conclusion, the FuelTech E85 system offers significant power gains for both turbocharged and naturally aspirated engines. While the exact gains can vary based on multiple factors, many users report impressive results that justify the investment. For enthusiasts looking to maximize their vehicle’s performance, switching to E85 with the FuelTech system is a compelling option.
