There are few people that would drive the 940 hp Dodge Demon and come away thinking the monstrous muscle car needed more power. But horsepower is the ultimate want: you rarely need more, but you can always appreciate and want more. More power just what the owner of a Dodge Demon who runs YouTube channel Demonology wanted, and he’s getting more power in the best way possible. Rather than upgrading the standard engine, this Demon now has the Mopar Hellephant crate engine.
As a reminder, the Hellephant engine was revealed at the 2018 SEMA show, and has been sold in very limited numbers. It develops 1000 hp, but based on the dyno test video below by Demonology, there’s a chance that massive number is underrated.
According to the video title, this is the first ever Hellephant powered Dodge Demon. And according to the dyno results, the motor is making 944 hp to the wheels. Dodge measures the Hellephant power at the crank, and assuming the standard 15 percent driveline loss, that result could mean 1,100 hp at the crank, over 100 hp more than Dodge claims. But a few details in the dyno test show that may not be the case.
First, not all dyno machines are made the same, and can yield different readings. So like any dyno test, this one should be taken with a grain of salt. Also, the video shows the car is running on E-40 fuel. The Hellephant engine is designed to hit 1000 hp with 93-octane fuel, so upgrading to E-40 probably boosts power. That 15 percent drivetrain loss is also a generalized number, and the Hellephant in the Challenger Demon platform could always be different.
No matter what, though, it’s exciting to see the Hellephant engine finally going into builds, after delays. The video also shows it’s very possible for it to run in the Challenger platform, too. Best of all, we see why it got the Hellephant name: the shriek of the supercharger, intake and exhaust all put together really does sound like an elephant from hell.
