Looking to see what you guys fuel system consist of at 800ish hp level. Will dual walbros with 80lb injectors get it done??

Walbro 255's seem about maxed out at that level, there's the aem 320's for an in take option, I used the squash in tank 450's for my car they should be good to 1000 or more. I'd upgrade your feed/return lines too if you are in there. it seems like 80's are the min injector to use, I have some Bosch 1000cc I got used, but lots like around a 127#/hr injector for much more than 800ish.

I'm running lonnies dual 340 setup, -8 feed, -6 return & FIC 2000s. I recommend going with those injectors and the 450s if u can swing it, if not the 340s and 127s would work but you wouldn't have much room to grow.

Dual 450's here with -10 feed and fic 2000. It's a big system but allows e85 and plenty of room to grow.

Dual AEM 320's, -8 feed, -6 return and 127lbs bosch injectors. Should start turning it this week shoot for around 800.

I suggest properly sized injectors and staying away from the 2000cc craze lately. They are too big for 800whp. Fic 1000 or the 127lb injectors are a good choice IMO.

80lb injectors are fine with enough pressure. Been discussed 1000 times. As well as what pumps to use and why.

For 800+ whp on 80lb injectors. Base pressure starts around 65. 3 255 walbros will do it. 3 044 bosch pumps if you want more reliability and a much better pump.

2000cc injectors are extreme overkill IMO.

I'm still a gen1 355 but I have a magnafuel mp4303 (protuner 750), holley 120lb hr injectors with 50lb base pressure. Dynod 720whp at 15lbs and was starting to spin, have it on 18lbs now and am around %90 duty cycle, going to raise the base pressure this year. E85, no meth or water injection, idles and cruises great.
