I plan on switching over to e85 and getting the atp turbos. What I am wondering is what all will I need to make this happen. I assume bigger injectors(please offer suggestions). Do I need an aftermarket intercooler for the bigger turbos? (I have a non PP). Who is the best e85 tuner? And any other questions I should be asking that I dont know to ask please answer, I just want to know what I am getting myself in to.
E85 larger turbos etc

E85 you will likely need an auxiliary intank LPFP to supplement volume, and a highflow HPFP as well. Injectors were not needed in the last setup I saw, but then it was PFI supplementing the OEM GTDI setup. So I would plan on Deatschwerks injectors as well.
Says Injector Dynamics guy LOL! What is your recommendation for GDI injector then?
ecopowerparts.com can sell you the aux in-tank pump (not to be confused with BoostAPump).
HPFP, I would go all out with LMS of course! XDI has their own line, but I have no data on how well they perform. StealBlue has already reported positive results with the lower level upgrade from them. I am sure the LMS pumps are tuneable by other vendors as well, but probably not to as refined a level as LMS can (being an inhouse product).
I could not say for the DI stuff. However, I've had most of my DW stuff fail, and at least half of every customer cars I've worked on and tuned. Had one stick open and flood until it dropped out of the uppipe.
I stay away from DW completely
Any recommendations then?
you can run e85 yes, with the fuel pump/fuel lines upgraded. I am not sure how much of the volume was handled by the PFI portion of the custom intake manifold you can find at ecopowerparts.com, but the injectors were stock. So I believe the stock injectors can handled e85 to dole out the max safe power levels a stock block can handle, and then some. For longevity reasons, I would build out the block if I were going beyond the DD levels of 400+AWHP/500+AWTQ. Yes, you can run the 600+AWHP levels with stock injectors and proper tuning, but ...

You cannot run 600+ AWHP with stock injectors unless your running NOS.
You will not only need larger turbos but auxiliary fueling, I don't believe any of the guys running HPFP have hit that and I know of one specifically that upgraded injectors and HPFP and used boost pump and now goes through in tank pumps like oil changes.... Call LMS and ask them what is peak power. I'm guessing 530 ish… There are other options, Myself and one other are currently running the intake from ECO that Mike has, same build ish with some different parts and we are in the 580 - 600 Awhp range.
I know LMS recommends injectors to run e85. Do you definitely need forged internals to get 500+ whp? I'm sure a full e85 tune and bigger turbos would equate to more than 500 hp and LMS didn't tell me I needed to have forged internals for that?
^^^ exactly this. My point was more about longterm reliability than anything.
In the days of yore, engineers would overspec products by 30% and people would be amazed by how long things lasted without unusual amounts of maintenance. For 500 awhp you dont have to get into aux fueling IF the tuner says you dont need it. But adding the higher spec fueling components ENSURES you have headroom in high demand situations. StealBlue can tell you how much of a difference he feels with the entry level HPFP while running merely E30. E85 gets you even more octane, but also pushes pumping volume needs that much more. Try with stock components, then make your decision. Pretty easy to drop in an HPFP.

I really want to push the drive train to the max power I can realistically believe I won't have problems all the time (racing a few days a year at the track) 500 whp is just what was said here that s why I said 500 whp, I would prefer to be 580-600 or around there.
Bpd runs 500+ tune file for "DD" purposes, but he also has a built block with bigger turbos. I would say 450 is a hard barrier for stock blocks. IIRC, it was suggested at a minimum to tighten down the heads with ARP studs if you wanted to go further. Big turbos help with lowering the psi neeed to achieve that level of power, so that would be a must.
