    Started running 25% E85 mix a while back and of course it ripped ass right away. We know that to be true. I then started using methanol as an aux fuel source. More kicking of the ass. Now that the motor is almost built, I`ll be running even more methanol. The question is would the amount of methanol I`m running (19gph) be just as effective with 93 as it was with E25? Will I be able to go back to 93 and pick up the fuel headroom and keep the benefits of alcohol, or is the E85 still playing a role despite the crapload of methanol being sprayed on top of it? The short version: will the car make the same power on 93 w/ 19gph of methanol as it would with E25 and the same amount of methanol?

    Yes

    Yes, and yes. Keep in mind if you remove alcohol alltogether but keep the timing benefits that come with it, she gonna let go. Basically, if your aux fuel tanks for any reason, you're done. With E25 in the tank, you *might* be able to survive such an occasion (look back on why mine let go and how many times, for instance).

    It can, yes. It could also make more or less, depending.

    Excellent point. I suppose I will just spring for two maps.
