I'm just surprised. Not more cars have done it. My personal car on stock internals with no cams no forged Pistons or rods ect. Completely stock with 102k on the clock. 661whp and 602 trq were its best numbers. Did 656 the run before. I didn't think I was the only over 650. I'm sure it's short lived to be the only and realistically I see 7 coming from others in the future. I think you are absolutely right. E85 and tuning is key. We made my numbers on e85 on 25psi from the sport 700s I ordered from you guys.
