That system will do great with E85. I run the same system on my 03 cobra and on our 2010 GT500. The cobra hasn't been tuned yet but the GT500 made 1040rwhp on E85 and the fuel system worked like a charm. No need to upgrade the lines as the Fragola 8000 series pushlite hose works very wel with E85.
I am basically running the same setup for my E85. I am just modding the Fore hat and running -10ans all around. Also running the best E85 lines on the market.
