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?

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.

Don’t throw out the Hellcat! It is still a monster.

So let me understand please. The Helcat Redeye I ordered and will be receiving in a couple of weeks has the same engine as the Demon? It can be upgraded to the 840HP?

Be cool. Could be a guy who honestly came here for the info, he is blessed and for a change can be someone who traveled down a good road! How many of the opposite stuff have we been treated to over the years?

@Xtra Octane Merry Christmas! Tell us about yourself, obviously some are surprised on this forum that is full of passionate AND very informed Dodge fans that you admitted you did did not know a very fundamentally good thing about your new car.
