Im thinking about making around 400 rwhp on a stock motor, ditching the FMU

thinking about either running 6 or 8 # out of an strim, stock cam, and maybe some ported budget blower heads (hogged CCs)

what size injectors would i need to run, and would an inline booster do the job ? or should i get rid of the inline pump for a high volume intank pump ...

how much power could you expect with 6 and 8#s with stock heads and headers .. basically a stock motor

(damn im starting to sound like a noob but i guess i am a noob when it comes to boost)

 

When my engine was stock I dyno'd 370 rwhp with a 6# Vortech S Trim and JBA headers (M6). If you go any higher than 6# you need an aftercooler to stay out of pre-detonation. I ditched the FMU and went with 36# SVO injectors and custom programming. The stock fuel pump with the TRex in-line supplied enough fuel. If you plan to keep adding power (heads, cam, pulleying up) you'll run out of fuel. I stepped up to a 255 lph Walbro in-tank pump and it's supplying my 527 rwhp (blower) and 580 rwhp (blower/nitrous) setup. I'm still running the 36# injectors and haven't maxed out my injector yet. If I had to do it over again, I'd have bought 42# injectors for more room for growth.
