CJM Report: Effects of E85 after 3 years?

SgtGoldy

to be honest I didn't know it had anything to do with safety. I use it cause its higher octane and cooling properties. Paired with my tune it's amazing how much of a difference it makes. It also allows me to boost at 22psi

but to answer the NA question:
This brings up the idea that just like adding high octane race gas to a stock motor on stock timing, you will see little to no gains, the same is true with running E85 with no tune. In fact, you can actually lose power not to mention it takes 20%-30% more E85 to reach stoich so I would doubt the car would idle much less run on E85 without a change to the cars ECU to tune for it. E85, like race gas, is for those of us who are pushing cylinder pressures to the limit of detonation. What “potentially” makes it better than race gas is the price. Currently E85 sells for around $2.75 a gallon.
