What do I need fuel wise to make around 650whp on boost I have a walbro fuel pump what else do I need like injectors and stuff

What walbro? A single 255 wont be enough. Im also trying to figure out if a single dw300 will be enough for that power level.

Anyone else got an opinion

Ive heard alot of guys on here say they can run 650rwhp w a dw301, theres other options like the racetronix 340 but it requires drastic wiring changes to be safe and a different regulator, or u can go w a double pump set up. Either way without knowing more specifics it wld be hard 2 guess on injectors if i had 2 i wld say that 60# should be enuf. At that hp rating fuel system will be a very small part of what needs to be changed.

Dual walbros, 80# injectors, stock rails and lines, and a FPR is what I am using with E85. I am shooting for 700+ this spring (made 606/570 last fall through unlocked 80e), so you will be fine with 93 octane on that setup.
