I’ve been wondering for a while now what the difference is between a hellcat and hellcat redeye. Beside the 90 hp difference And a few cosmetics like the hood, what in depth differences are there? Any that stand out specifically?

Challenger or Charger?

And you really should repost this in the correct section of the forum.

There's a lot of info on line you could check out before asking the forum that kind of question. If you have to ask you may not deserve the answer. So, you have a Hellcat and don't know the difference?

I have neither. I am looking to buy one shortly and would like to know the difference. Calm down

Also, from 2019 and up it's 717 horses for the standard Hellcat. 2015-2018 had 707 horses.
On Challenger only. Charger goes to 717 standard on all Hellcats 2021, I think.

Demon engine with stronger internals and bigger blower was enough to sway me. The extra hp is just a bonus. The stronger axles, driveshaft, etc was just a bonus bonus. The dual fuel pump set up is also nice.
Also dont forget they just released a RedEye dealer install hp upgrade with 885 available hp.

One of the best articles on the engine. It has so many facts in it some of us forgot all the reasons we have purchased a Redeye. A Look Inside The Dodge Demon’s 840HP Hemi

As per above, soon we can get factory power upgrades from Dodge for the RE that may make them even more desirable with the strong internals.

IIRC, stouter driveshaft and half shafts, better connecting rods that are actually forged not sintered, and MAYBE heads from T56 aluminum heat treated to T6 (or maybe all Hellcats have that feature) This just off the top of my head, as I do remember kind of envying the list of modifications that, to me, were not just marketing fluff but actual engineering improvements.

I don't think it ends at "slap a 2.7L IHI blower in it to replace the Hellcat's 2.3" by any means. They (Dodge) don't want warranty grenades.

Specifically…
The crankshaft, connecting rods and pistons are all completely unique. The crankshaft is a forged alloy unit that received revised balancing and induction hardened bearing journals. The connecting rods are powder-forged units with upgraded shanks, big ends, tapered small ends to reduce weight, and ultra-high tensile strength ARP 2000 fasteners. The pistons are also forged and feature an inclined box well design for additional wrist pin support. Piston to wall clearance was increased 30 microns to accommodate both piston alloy and the heat expansion associated with the horsepower power level. At peak power there is a compressive loading of 11 tons on the piston and connecting rod.

The cylinder heads are cast from A356-T6 aluminum for its strength and heat-shedding properties.
