The E85 went well. I have it on a flex tune so I can swap to normal fuel if I choose. I used dedicated E85 race fuel for the runway event and had no issues what so ever. The only benchmark I have for improvement is the top speed against one other S550. It was an auto, same year and on unleaded. I out paced hime over 1000 metres by 4 km/hr and I have a manual.
Where I live E85 is actually more expensive than 98 ULP so economically it doesn't add up, and being winter here at the moment starting is a little harder, but not a show stopper.
All in all if I know I'm doing an event I'll run the car down and use E85, and unleaded for day to day. Hope that helps.
