with the 28s you can get away with it, you will be maxxed out but it will work. I did it for 2 years this way with boltons
Stock fuel pump, I think so but you would have to find out

not recommended. if you are truly using E85 you will be beyond maxed out. I'll put it this way, the car in stock form, if you put exhaust and intake they will beyond the accepted maximum.

I put my car on e85 last week. I have headers, exhaust, no cats, and the car came with some sort of cam installed, and i just put a ractronic fuel pump kit in. I'm at 4500 feet elevation so i can get away with more as we are down around 18% power. At the top of the gears i was hitting 100% duty cycle. a/f didn't lean out and was actually slightly rich. so for right now i'm ok, however running injectors this hard is bad.

at sea level with the same mods, no way would the stock fuel injectors keep up.

the SAE standard for injectors being beyond "maxed" out is 80% DC

My header/ls6 intake/lid car leans out at 5600 on e85 and brand new stock pump. That's with 37# injectors last month and again today with 60#ers.

stock pump is a 190 liter per hour, this is the equivalent of 8 x 38LB injectors.

255 liter per hour racetronix/walbro equates to 8 x 51LB injectors.

This fuel sticky is here for a reason.

E85 requires (I think) 50% or greater upsized components. refer to Runns posts: HERE

I'm still running on gasoline so I can't give exact details, but I know you have to WAY upsize components. doubl 340s or greater... A1000s and 200 LB injectors...etc
