FI Tech is compatible with E85, I asked them that prior to purchase. They said deduct 30% of the advertised HP level for that injection unit and that is the power it will run on E85. So that should put me at max 840 HP on the injection system.

Andy - thanks for the math! So the smaller pump should be fine as I believe the injection system doesn't need that high of a PSI. I will double check with everything will be OK with the E85. I did read that I will need to remove the foam from the cell as the E85 will eat it. I am not sure if they have compatible foam now or not.

**Just read that the big pump is compatible with E85, the small is not **

I remember the PSI requirement being around 51PSI, I am trying to find the number....
