Need HELP! Injector choice for E85 850-900 RWHP

[Limon_Svt]

been going back and forth between injector choices, will be running on e85 and 91 octane
Current build is almost finished and I just need to order my injectors but I don't want to end up buying the wrong ones
04 cobra Built motor 9.1:1 compression
Whipple 3.4 crusher 3.1 RR upper for e85 & 4.0 upper for 91 octane. Stock lower
Should be around 27 psi on e85

Fuel system consists of lethal return style fuel system with -10AN feed and -8AN return with dual Walbro 465 pumps.

I'm guessing car will make 850-875 on e85

The real question is what injectors would be good for this setup?

Was looking at the Bosch 105# injectors or the id1000s but I've been reading everywhere I might be maxing them out will I need ID1300s? If so I better start saving because they are hella pricey lol. Thanks in advance guys! First post on SVTP

I didn't now you could get a 3.4l to turn slow enough to work on 91 octane.

I suggest ID's, they have a calculator on their website.

4.0 upper and longtubes should put me around 17 psi. Also 4000+ feet above sea level lol

And which ID's? There's a big price difference between the 1000s and 1300s
I've seen a couple people on here post about making high 800s on the Bosch 105s, just need someone to chime in

First, welcome to SVTP.

Second, both your choices will make 900 RWHP with the proper pump/fuel pressure on E85. I prefer the ID's myself but I have tuned both.

Thanks for the warm welcome. Lol and I might just go ahead and get the 1300s, room to grow for later and won't be maxing out the injector duty cycle.

They are a great choice! Can't go wrong with them. Yes, they will leave you more room to grow.

ID1300 is also stainless internals, less worry with E85.

Can't believe I dropped 1400 on a set of injectors lol, I'll keep you guys updated on the dyno day! Any Guesses on the hp I'll make?
