613hp on E85 and pump was at like 93% efficiency so they stopped at 613. That's about the limit on that pump. I have the single 450 E85 Walbro. Others have said they made over 700 on this pump with a rewire. Start reading from ETS Michael's comment and into the third page from my dyno results thread: https://www.evolutionm.net/forums/ev...5-2-4lr-2.html

I know over 750 WHP on C16 or E98 I think the famous 9 second Evo X owned by Colo Performance had a 450 only but they took it off.

Ive seen single walbro 255 do 600 WHP on C16......
