[QUOTE="Voltwings, post: 14453615, member: 155561"] E85 actually has an effective octane of about 160 in DI applications ;) most other platforms don't even use 100% E85 when doing so to save injector headroom. The common blend with the Mazdaspeed platform was 25% E85 per tank, I took my own car down to 2 gallons per tank (16 gallon tank) before I started seeing any knock, and was still significantly above where I was knock limited on 93 alone. DI really does have some amazing perks, it just sucks when you run out. Would make no difference if its pure E85, winter blend, or watered down other than fueling trims, you'll still be able to run right past MBT with very little E85 in the tank. The problem in this case is people get greedy and either pass MBT, or just keep adding timing and end up with blistering low end torque that leads to bent rods and windowed blocks. [/QUOTE]
