How much HP does E85 add horsepower?
The benefits of E85 really come from the higher octane (up to 110, depending on ethanol content and quality). This allows some of the same benefits you see when using methanol injection, meaning you can run more spark (if needed) or boost. This normally translates to 25-50 or more horsepower on a forced-induction car.
How much HP can you gain from E85 and tune?
E85 fuel 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, gaining up to 20%.
What do I need to run E85 on STI?
At minimum to run E85 you will need upgraded fuel injectors, upgraded fuel pump, and tune on the EJ engine 2002-2014 WRX, 04-current STI, 05-12 LGT/OBXT, and 04-13 FXT. On the FA engine (2015+ WRX) you will need an upgraded in-tank fuel pump and a tune.
Does E85 ruin your engine?

How much power does E85 Add WRX?
364.18whp

How much compression can you run on E85?
According to Wusz, even given the cooling effect of E85, his recommendation would be to limit the static compression ratio to 13:1 on a 4.00-inch bore small block and slightly lower in a larger bore engine like a big block Chevy.
Does E85 get better MPG?
MPG. Due to ethanol’s lower energy content, FFVs operating on E85 get roughly 15% to 27% fewer miles per gallon than when operating on regular gasoline, depending on the ethanol content. Regular gasoline typically contains about 10% ethanol.
Can you run E85 on stock turbo?
Yes, you can run 100% ethanol as long as you have the fueling to support it. Back in 2014 my HPFP and LPFP were very strong and I had no issues running full e85 on DI only on stock turbos. To be honest, you wont gain much by anything after e60 IMHO.
Is E85 better than 91?
E85 has higher octane than regular gasoline. This means that E85 is a lot better for your car’s engine than regular gasoline. It is also a cleaner fuel with lesser harmful emissions. On the downside, E85 burns faster and produces lesser energy than gasoline.
Can you run E85 all the time?
Because ethanol attracts water it can create rust and seal breakage over time, and if E85 is left in the fuel tank for long periods it can attract more water vapor and potentially cause engine damage.
