Decided on the 8474 for my next upgrade. Now it's time to sort my supporting mods to ensure I have enough. My lil beater is full flexfuel. So I have to ensure I have enough fuel for E85. Currently running 1k/1650 combo being fed by -6 from an E85 Walbro.
My thoughts are to upgrade my feed to -8 from pump to rail. Upgrade to an Elite intake and run four secondaries (batching two injectors per injector driver on ECU).
Now the fun part, Injectors. Keeping the 1k EV14's should keep me safe for idle (whether gas or E85). But how big should I go on the secondaries and be safe?
Second thing is the pump. I'd prefer to stay single, but don't want something that's louder than my radio. The Walbro has been one of my favorite updates because it's crazy quiet, even though the pump is literally within arms reach.

Suggestions?

You will need twin 450s for anything above 430rwhp on pure e85. You will also want the ID fuel filter as e85 is pretty dirty and proper filtration is very important. IdX brand injectors should be used because of their stainless internals. Id1350 primaries and 4x id1750 secondaries.
