    E85/Flex fuel for the win!

    This was E50-E60 fuel in a VT with stock engine, stock turbo, and stock catback still on the car!

    Pulls cut early but look at the boost to make these numbers..... 257-265 whp SAE cf.

    Those NGK race plugs looking good as well!

That is a success in my book considering 93 will not get close to this before misfires and diminishing power.

    Now, some cons at the moment are hard starting in cold ambient, occasional hesitation in low rpm and load when cold, and beginnings of spark blow out at high load/boost and high rpm. These are partially due to needing new coils but are mostly due to the nature of the fuel in cold conditions on our motor.

    I know how to resolve these issues so now just a matter of doing it with an ecu not designed to run on Higher E blends.

    Here is a screenshot of absolute load on E85 at 5k rpm and 0 misfires. Boost reading is max of map sensor but also show what gauge reading is for boost during the data log.Attachment 97018Attachment 97026
    Nice work!!! Question, do you have a log of the commanded fuel pressure at the rail? I'm curious to see how the pump is behaving on e85.

    Rail pressure stays pretty close to commanded pressure
