    e85 fuel injector chart , per lbs/min boost

    i found this info the other day, and if its right on, its a good starting point for people looking into using e85:

    info originally posted by dark horse from dsmtuners:

    I'm posting this because I keep seeing so many questions about running E85. "Will _____ size injectors allow me to run ______ turbo on E85?" Here is a guide that will answer all of your questions.

    This guide takes the following into account.

    1. All injectors flow exactly what they say they will. IE: 720cc injectors flow exactly 720cc.
    2. All injectors flow exactly the same. IE: All injectors are perfectly matched (which is impossible in the real world)
    3. Specific gravity of E85 is 0.79.
    4. All calculations use a gasoline AFR of 12:1 - this equates to 8.05:1 in E85 #'s. Meaning - your wideband will read 12:1, but your actual AFR will be 8.05:1. Your wideband doesn't care what type of fuel you use, and will display numbers based on gasoline stohic (14.7:1).

    With that in mind, on to the numbers.
