Hey Guys,,I came across this excellent tech article in the new DSport magazine,, Aug. 2013...Great reading if you ever wondered about different fuels ..
It covers all aspects of tuning,,fuel systems and dyno results with 91oct,100oct and E85 fuels in depth..Even though it is a GT-R, its close enough to show effects and results of each on it..
Yes I know some know it all already but others may not and want to learn or confirm, as I like to educate myself with as many examples and facts as possible...
This is the best article I have saw/read on this topic with a car as close to ours in HP and being twin turbo on a true street car..

 

Thanks for sharing that! Good stuff!
