Hey guys i have been searching on here trying to figure out what the largest injector i can use with my fuel set up. I have twin walboro, 255's in tank 8an feed 6an return and nasty performance rails I currently have 60lb injectors and im afraid they wont be enough for my HP goals of 800 on pump and possibly running e85 if im going to upgrade my injectors I only want to do it once and have room to grow. I know I may be limited by my fuel pumps but am looking for suggestions. Thanks.

pump to 85 is a good difference. you may not be able to only do it once

for sure 60s wont be enough on E85. It could be done on gas with enough fuel pressure.

If I upgrade my injectors how big could I go with the dual walboro 255 before running into issues. Would the Siemens 83 lb injectors be a good fit?
