I am building a motor and puting twins on it. I'm hopeing for about 700 -800 hp. I was wondering if i should put dual cp3 or if a mod cp3 with the dual feed line will work.

I'd do the dual cp3

Let's take this one to Fuel Systems for continued discussion.

most will probably say duals.

Duals... as long as you only need/want 1 alt.

what is alt.

what is alt.

altenator

Righto. Most people have little to no use for dual alternators, but the value in it if you don't need the extra amperage is the backup factor... one alt dies, you've still got the other one to run on instead of being dead in the water.

Duals.

Stock pumps are reliable. Modded ones can be less reliable.

Dual stockers will push all the fuel you need to hit 8-1000RWHP.

It will be more $$$ initially, but if one ever craps out, you just slide another stocker in :)
