Default Fuel system for 800 rwhp

I'm getting close to finishing my project and I want to make sure my fuel system is up to par. I have a bosch 420L pump with 8an feed and 6an return. I'm planning on doing apx 550 on motor and the other 250 on nitrous. Will this setup be enough? Should I do a bigger pump or run a seperate system for spray? Thanks for ideas and suggestions.

A 420L is good for roughly 750 engine hp. I'm running two 420's and it holds steady pressure at 700rwhp. Add a second pump for the n2o.

Do you just run the pumps in series to each other?

Series won't add the volume that you need. Parallel is the way. Don't run both pumps at the same time while cruising or it will heat the gas. Have the second pump activate with the n2o. Harris Speed Works can set you up.
