I have a fully built ZC that will be boosting about 20 psi, 25 max. Horsepower should be well into the 300's. I was thinkin 550's but after reading a few threads im starting to think otherwise. I'd like some info on what injector is equivalent to what hp range. Also, can i use my stock fuel rail with that much flow? Thanks

 

injector size is not in what you will boost but in hp rate
do a search im sure you will find something

 

i did a search and didn't find what i wanted to know that's why i posted
