With corn, that i am unsure of but i would guess its up over 700whp. It all depends on the size of the line and pressure you run. I have heard/seen 750+whp posted on twin walbros and E85. keep in mind, awd drivetrain loss and on a dynojet it would be dam close to 800 hp at the wheels PLUS, remember this is with a stock fuel pressure + 39 psi of boost. walbros fuel flow is not very linear at all, the flow curve of a 255 is almost exponential as it drops off past 75 psi I keep getting all these evos confused there are too many! --- _[View the full topic](https://forums.speedlife.net/t/first-700whp-tune/205049)._
