Injector size recommendation for NA E85 coversion

I'm looking for recommendations for injectors that will effectively run E85 in my 2017 392. I am considering a lower output supercharger later this year as well, so I'd like to make 1 purchase with that goal in mind also.

I would like the ability to run an E85 tune on the track, and a 91 octane around town (E85 is about 1.5 hours away, so my cans will be filled periodically).

Are there any other considerations that I should think about?

Thanks!

2017 Challenger R/T 392 (Scat Pack Trim)
Redline Pearl
6 Speed

Current Mods:
  • Barton Shifter
  • UPR Catch Can
  • Speedlogix Skip Shift Eliminator
  • Hellcat Air Box and Filter
  • TAZER

Look for a thread by @chizzle1 , he is making considerable power and switched to E85 which not only required bigger injectors but a bigger fuel pump. In fact, I think he ran a return style set-up.

Here is the thread I was referring to.

BTW I don't think the PCM can be set-up to run gas...then E85 without re-flashing. I know a lot of guys want to run flex fuel and HP tuners has a patch for it but it is not as simple as..."just install the patch".
