How Much Pump Gas Powa???
Thank you to everyone for the feedback and I will post pics of fresh plugs in a couple weeks once I get back home.
Really quick, what is everyone's thoughts on anti-seize on the plugs?
NGK says not to use anti-seize on the threads because it makes over torquing and thread damage easier.
I'm just thinking it would make reading the heat range easier.

So, let's talk E85 now since there are several E85 stations close to where I'm looking at moving.
Current pump gas fuel system consists of the following:
Stock tank, modified bucket with twin 450's, both on hotwire circuits, one on a Hobbs.
-08AN Feed / -06AN Return into stock feed line.
FIC 1000cc Injectors, aftermarket fuel rails with Aeromotive BRFPR -06AN design.
Thinking I want to build a fuel system for 1,200whp which would cover any future mods.
Here's what I'm thinking but would love some input from the E85 guys.
Stock tank: Triple in tank 450's (on the fence about this)
Single in tank 450 and a Weldon D2035-A (Pricey plus I'd have to sump the stock tank somehow)
Single in tank 450 feeding a surge tank with triple 450's (Looking at Radium, still kinda pricey)
-10AN Feed / -08AN return or -10AN return?
Bosch 210's, same rails, Aeromotive BRFPR for -08AN lines?.

Couple options the way I see it.
#1 I’d buy a flex sensor and see how far you can get on a 50-60% E mix. You already have a pretty capable fuel system.
Next instead of removing and replacing things. Why not Just run another inline pump of some sort like an Aem400 and plumb it to the regulator with -8. Most regulators have multiple inputs.
They will pull from a fuel tank, but a sump would be better. That way you could use what you have and just add to it pump and fuel line wise as needed. Guess you could buy the big dollar hangers and just run 3 intank pumps. But that seems like it would cost more and require more work. Since you’d be replacing the current lines.
Another (possibly stupid) idea. Just add a 5 gallon cell with its own AEM400 pump and regulator. AEM400’s already have a check valve so that wouldn’t be needed. Have it come on with your 2nd boost pump.

I built a 5 gallon cell with provisions for three 525's into a 10an out and 10 return, also has a 10 vent. I went this route to have more options later on. Once I swap rails its 10 to reg, 8 in/out with 10 return.
Either way if you can 10 feed and return, make sure you have large enough vent. Looks like your cheapest option is triple intank if you can fit a third and fuel line swap.

I wouldn't call that stupid. However I would "just a suggestion" is if you did the cell with the additional pump like a 525 and check valve then route it into a Y with a 10 out to feed everything and "possibly" use you existing 8 as your return. I would either way use a 10 to feed especially if your buying hose.

I had been told that I'd have to swap to a newer 00-02 F-Body ECU to accommodate that.
Forgive me but if I'm running E85, what would I need the additional fuel cell for, would it be acting as a surge tank?
I assume since I'd be running a pump/E mix that it wouldn't require me to run dedicated E85 fuel line?
My other concern is where I'd put the fuel cell, it'd have to go in the back hatch area of the car in the same space as the driver which I'm not to keen on.
I had the same reservation about the meth fuel cell being back there, it at least the tank for it would have a heavy-duty screw on lid.

Chris1313 sells a triple tank hanger that isn't to crazy expensive, guess I could go that route reusing my twin 450's and maybe add a 525 as well.
Then see where the rest of the system taps out.
I’ve never used a factory ecu for anything. I believe sloppy mechnics did a video on this though. Obviously, the flex fuel ecu’s can. But I swore he had a video out that shows how to do it with an older “non flex” ECU. You had to give up some sort of input/output. But he def. did it. As far as how many “early” ECU’s there are and which can run flex and which can’t… I couldn’t tell you off the top of my head. It’s worthwhile though. Even if you had to have your ECU modified or trade your ECU in for a “flex unit”
With your current setup a surge tank wouldn’t be ideal as your main fuel supply is in your existing tank. Generally you use something like a factory in-tank pump to fill a surge tank. Then feed your “big” pump(s) from the surge. You’d have to rework everything to do that.
You would basically be adding another fuel pump for simplicity. Have you seen how the factory C5 AA corvette blower kits do this? They just drill and tap the poly fuel tank. Run an inline pump directly to the service port on the factory rail. Works pretty slick.

A single AEM400 is good for 500-600ish WHP on E depending on how its plumbed and supply voltage. Could simply plumb one to your regulator with some small easy to run -8 line. I wouldn’t go larger as its dedicated to a single pump and -8 can easily flow what that pump can handle. Once you start adding multiple pumps to a single line is when you need to bump up the line size IMO.

We don't have E around here or I would have used the stock tank with one 525 main pump inside and dual externals off the sump for a total of 3.

Only reason I didnt is because when I went to install the new tank it was completely rusted inside, so I grabbed some 6061 plate i had and whipped up a cell.
For a street car simplicity over complexity will keep you off the side of the road waiting for a tow. Kind of why I like the multiple pumps in same tank, Something goes wrong swap connectors and get home. With a surge tank if your uplift pump fails your dead in the water.

Verdad Gallardo As of right now, no it will be used as a primary only. When i reinstall the factory tank options are run as a large surge or keep as a secondary.

He states that with his hat and twin 450's is good for 1,200whp on E85 so I could just go with that pump hat, and upgrade my lines to E85 compatibility, see how far these 1000cc injectors will go and upgrade those once tapped out so really it wouldn't take as much as I thought it would.
Now its just gonna depend how close I can get to living next to an E85 station.
1000cc injectors aren't going to go far with e85. I've got Chris's setup in my car with 2 450s, and no major complaints. Unless you want to drill the tank and add a sump/pickup, or run a surge tank it's the best bet. They aren't overly loud but since the tank isn't baffled, and they don't have the stock fuel bucket - I don't let it get much lower than half a tank. I've heard of guys having issues when under half a tank but, I've always had steady fuel pressure on my logs. I race with it full, which is the opposite of how I ran it N/A.
As far as the ECU - many ways to do it, depending on the budget, and what you want. It's easier to make that decision when you are the one tuning it.

I could mount the pump/s to the bottom of the t-top well and it'd be below the pickup then.
If the twin 450's proved to be insufficient, a single AEM400 looks perfect and holds flow way better at like voltage/pressure compared to the Walbro 450.
@nocooler I always keep the tank full as well, I don't want to risk starvation plus I need the extra weight over the axle to help plant the tires lol.
