Building a forged bottom end 5.7 with twin 61mm turbos. Looking for 800rwhp but should I be good on 80lbs injectors and if so, will my stock fuel rail be ok? Or should I upgrade to a bigger one?

Set up:
Iron 5.7
CP forged postons
Lunati forged pro mod rods
317 heads 3 angle valve job
Tick Performance Cam
LS6 intake
twin 61mm turbos
15-18lbs boost

 

I think the stock rails can support those 80s at full tilt.

 

Ok cool Thank you! Next question, which I should have asked first ... will the 80s be enough? Or should I go 100lbs injectors?

 

what fuel? e85 from what ive read would be getting close to 100% DC at 800 if not maxed but honestly dont have much hands on experience yet

 

93 pump gas.

 

should be okay on injectors, im sure someone with more experience will chime in though, but depending on fuel psi they should be able to take you pretty far..

 

Way more then enough injector for 800rwhp on gas.
