Your still in Germany arent you? Which is cheaper over there? Cause here in NC E85 is about $2.99 a gal. where 93oct is somewhere in the $4.25ish range. (not right now tho cause there isnt any gas in western NC lol).

If the E85 is cheaper, just run that. No need to mix. Other than that what would be your reasoning for mixing the two?

 

gas is still $4+ a gallon here.
E85 is in euros and the euro is kicking the dollars ***. but the cost 1 euro a liter for E85 after the conversion it still cost more per liter for e85 compared to a liter of gas. esso is the only station that support us here, and they don't sell e85. reason why gas is cheaper than e85 for me is that we don't pay tax on stuff bought through the army, but since the army don't sell e85 I have to buy from the germans.
reason why I wanna run e85 is that I blew my motor while street tuning on pump gas, detonate at 23psi melt a piston. AFR 11.5 timing 12 degrees

ran 20 psi on a trash can stock motor using e85 the motor is still in excellent condintion. note t67 turbo.

I wanna make 600whp I don't think 1000cc injectors will support that using 100% e85 . I also use methanol injection. I am also setup for a 75 shot of nitrous which I will use.
