I believe Brian in MN has been working on that for a while. From Brian's and Shiv's research, about 50% ethanol is where you get some really high power/torque numbers, but I think Shiv also said stock turbos won't see much if any benefit over 60%. The original FF thread logs and dyno runs were done with a 50/50 E85/93pump (E10) that measured 60% ethanol via the fuel comp sensor.
