Here I am putting around at 370whp like it's a good time. The bar is very high!

Awesome what these cars can do these days. Impressive as it is. The stupid A$$ fender flares ruin it for me. I would rather put that drive train in my 2012 R/T. I like the 08-14's better than then 15's & up.

laugh2 Always a negative nancy no matter what... if it wasn't the flares, it'd be something else.

I'm sure they are built to handle even more power, just detuned so they last.

I like the flares. Amazing that there is that much power left as low hanging fruit! Jeez---someone is going to get 1000 rwhp without NO2 out of one of these soon.

Amazing! The Ford boys are all butthurt over the Demon, even the Chevy boys are laughing at them and giving Mopar thumbs up!

That’s what suprised me as well, usually you need a pulley change for that kind of hp. Seems like this was all timing and fuel changes

That has to be touching on 1000 horse power at the crank ....when is the crate engine out?

The thing I think a lot of people miss, is the Hellcat engine is not breaking at these power levels(some supercharger bearing issues)
The Demon so far seems to be able to handle 1000hp@ the crank and their not breaking pieces.
I love my old G2 hemi, but lets face it folks in stock form they wouldn't hold it together like these G3s are.

If they offer a Demon crate engine, I would have to think seriously about selling off the old toys and dripping one in the Scatpack.

I’d guess they do come out with one within the next year or so

How different are the engines? Cam, different blower?

Demon uses a 2.7L blower at 14.5 psi, Hellcat 2.4L @ 11.7 psi. Cams, I’m not sure. I think everything else is pretty much the same
Edit:apparently the cam is different. .561/.551. 224/240@.050, 109/137 lobe centers for the Demon.
Here’s an Allpar article with the differences:

I'll have my eyes open for the release.

According to that link, 62% has been changed from the hellcat to demon engine... way more than I figured.

Looks like better rods, better built crank etc.

I think the 62% figure relates to 62% of the parts value are different not that 62% of the components are different

Block, heads,front cover, crappy timing gear is the same ,
Rods, Pistons, Supercharger, cam are different


Truth has no agenda, but those with an agenda make their own truth.
Some of us are so open minded they only see their View

"This was achieved by introducing a new version 6.2-liter supercharged Hemi, with 62% of the content changed from the original Hellcat Hemi — including a new block, crankshaft, connecting rods, pistons, and supercharger assembly."

This is from the article... Looks like a redesigned shortblock, not just rods/pistons, cam etc. To me this means block, crank and so on.

I believe the only real difference with the block is its honed with a torque plate.

The other real power producing changes are camshaft, larger supercharger and intake.
