This will be interesting. He is one of a few guys tearing into them already.

Changed injectors and tuned the car for E already.

What all is involved getting a regular hellcat on e85? From what I understood it requires the PCM to be sent to HPT to have them modify it to accept a write from the editor. Otherwise is it just a matter of changing the stoich afr and installing larger injectors to start before upping boost and timing?

No shit, last video I seen they couldnt get the stock pulley off.
Very curious to see what it does with the smaller pulley.

It's on....

The Demon in stock form makes 14.5psi, which is what a hellcat makes with a smaller upper on pump gas. They use the same pullies stock, but the 2.7 vs 2.4 is the key.

Depends on whether or not you use Diablo or Hptuners software. Some tuners prefer one vs another. Barth for instance uses Diablo, which I'm new to, but have already figured out how to data log with the handheld and laptop if needed. The nice thing about Diablo is you can change tunes fairly quick with the handheld.

For E85 you need bigger injectors, boost a pump or twin drop in pumps and a tune. Some have done this just to their stock cars with great gains.
