What is the best et/highest horsepower on E85 and stock fuel lines?

[The_Six]

Talked to one of my supra friends to day and he runs e85 in both his cars he said the track only car had trouble but his daily driver didn't . His race only car sets a lot and must give the fuel more time to react with the air
