Whats the max you can get out of a walbro 450?
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
