Boosted vehicles are super easy to make more power with. You simply turn up the boost! However there is a limit to what you can do on this for the safety of your engine. This is why most tuners will suggest running 109 octane or if tuned for it, running C16 leaded race gas. The cooler burner fuel helps your vehicle run the increase horsepower and torque from the upped boost levels. At $10 per gallon though, full time race gas cars can get expensive. This is where E85 comes into play.
E85 is an alcohol based fuel that is 85% Ethanol and 15% Gasoline. Having a higher octane rating, slows down the burn rate of the combustion cycle. This means that it is possible to increase the boost level, compression ratio, and/or timing advance and return the mixture to a burn rate similar to that of gasoline, having a comparable level of ’safety’ in the cylinder, a similar mixture volatility, but albeit at a much higher power level.
On average it is not uncommon to see power increases of more than 30% in a turbocharged vehicle over “pump” fuel and more than 10% power increases are not uncommon over a comparable unleaded race fuel but again every application is different and there is no golden rule. The bottom line is though is it is unlikely you will ever see a car go backwards by making the switch, they will always make more power on E85. Because of the properties that make up E85, in most vehicles, it is necessary to change out certain fuel components such as the fuel pump or injectors.
The AEM E85 Fuel Pump is designed for in-tank installation on high performance naturally aspirated and forced induction vehicles. It flows 320 lph (84 gph) at 43 PSI (please refer to the chart for fuel pump horsepower versus pressure for various applications and fuel types). AEM’s E85 Fuel Pump features robust internal construction that is designed to withstand the low lubricity characteristics of ethanol and methanol fuels, and has been tested to work with ethanol fuels up to E100, methanol fuels up to M100 and all types of gasoline.
