Demon Performance is offering complete 2018 Demon engines

by Patrick Rall on

Getting parts for a 2018 Dodge Challenger SRT Demon is difficult and if you don’t actually have a new Demon, it is impossible to walk into a Dodge dealership and buy parts for the legendary muscle car. Every component made specifically for the Demon is placed on order restriction that requires the dealership to gather proof of ownership before selling any parts for the 840-horsepower Challenger. Since the Redeye shares many components with the Demon, the Redeye’s key parts are also on a similar order restriction.

This system is in place for a few reasons. Most importantly, it ensures that replacement parts for the Demon and Redeye are available if needed while also preventing anyone from buying up large quantities of limited production parts and gouging people on the prices. It also, in theory, helps to prevent the exclusivity of the 2018 Demon to some extent, but there is downside to the restriction.

Anyone who wants to build a Demon-powered classic, say a 1971 Dodge Demon with the 840-horsepower supercharged Hemi, cannot do so by ordering the parts at the local dealership. That classic Demon owner can buy a Hellcrate with 707 horsepower, or they can buy a long list of other production engines such as the 5.7-liter or 6.4-liter Hemi, but they cannot buy the Demon/Redeye engine or any of the parts that are specific to that engine.

With this in mind, imagine my surprise when I saw a post on Facebook this morning by the team at Demon Performance, announcing that they have a limited number of 2018 Demon/2019 Redeye longblocks available for sale. Upon seeing this, I reached out to the company for more information on these impossible-to-get engines and if you are one of the people looking to install a new Demon engine in a classic Demon, get your checkbook ready, as this is the real deal.

Complete Demon Engines for Sale

I spoke with Skip Patel, owner of Demon Performance, and he confirmed that they do have a limited supply of Demon longblocks in stock. Even though the average person with a Mopar project car in their garage cannot go to the dealership and order any parts for the Demon engine, the modern Mopar experts at Demon Performance are currently offering the brand new longblocks for the 2018 Demon/2019 Redeye. These engines are in stock now and as the posting on Facebook stated, they are available for $15,999, shipped anywhere in the continental United States. For those unsure, a longblock includes the engine block, the rotating assembly (crankshaft, connecting rods, pistons), the cylinder heads, the timing components and the water pump, along with the small bits that bring everything together.

The longblock assembly does not include the supercharger, the exhaust manifold or the engine electronics, but Patel explained that Demon Performance can provide those as well. In fact, the South Carolina-based shop can put together an entire, running 2018 Demon engine for your project car, complete with the full electrical harness, the ECU, the throttle pedal assembly and everything else that you need to run a Demon/Redeye engine in your classic Mopar.

Of course, while Demon Performance can sell you a stock 2018 Demon engine with 840 horsepower, they are also experts with Whipple supercharger builds and custom twin turbo builds, so you could get far more than “just” 840 horsepower from your Demon longblock.

In other words, if you have a classic 1971 or 1972 Dodge Demon and you want to install the powerplant from a 2018 Demon, Demon Performance can help with that right now. However, with the supply being limited and with these engines being nearly impossible to get, any serious buyers should contact the shop as soon as possible.

Details on Demon Performance

For those unsure, Demon Performance is not named after the 2018 Challenger, nor do they only deal with the modern Demon. The company started back in 2011, offering high performance upgrades for all sorts of modern American performance cars with a specific focus on making extreme levels of power from the modern Hemi engine.


Demon Performance campaigns the world’s fastest Jeep Grand Cherokee SRT8 called Suspect 2.0, which reached nearly 200 miles per hour in a standing half-mile, and Skip currently drives an X275 Jeep that features a Gen3 Race HEMI making well over 2,400 horsepower. That 2,400 horsepower engine was built by their DemonTKM engine program, which has built and delivered over 150 high performance Hemi race engines over the past few years – many of which have been used in competition in the Modern Street Hemi Shootout series that we cover here on Allpar.

In short, Demon Performance doesn’t focus just on the modern Demon, but their company is one of the few places in the world where you can buy a complete, new engine from a 2018 Dodge Demon.
