So my car has 426whp/470wtq on 93 octane and I was talking to my good buddy Brendan from BrenTuning and we decided to toy around with the E85. My car was on empty, so at the Shell I put in 7 gallons of E85 and filled the rest with 93 V-Power.
Our results...WTF! 450whp/510wtq!
***I know some people talk about the different dynos and I look at the gains. Try me if you want to...LOL.
