||I was a Chicago dyno attendee, and am also thrilled with the results.
I went from ~430 to ~480whp with my Sport 500s.
93 octane highway mpg ~21
93 octane fuel cost ~3.70
E85 highway mpg ~17.5
E85 fuel cost ~2.15
The fuel is ~44% cheaper, yet nets only a 17% reduction in highway MPG while delivering 11% more horsepower and 50% more driving enjoyment. I'm so glad I made the switch
