After an issue forced Mopar to delay the production process of its almighty Hellephant crate engine, the limited-run powertrain has started to reach the hands of customers and a Dodge Challenger SRT Demon located in New York has recently received this insane unit.

The Hellephant is a 7.0-liter supercharged V8 that pumps out a claimed 1,000 hp and 950 lb-ft (1,288 Nm) of torque. While Mopar has never said exactly how many Hellephant engines it is producing, we do know that they were all sold out within just two days. Prices start at $29,995 plus an additional $2,265 for a plug-and-play engine kit that suits most pre-1976 vehicles.

When slotted into this Demon and put through its paces on the dyno, the car pumped out an extremely impressive 944 hp and 877 lb-ft (1,189 Nm) of torque at the rear wheels. It is worth noting, though, that the car was running on E40, a mix of 40 per cent ethanol and 60 per cent petrol, during its dyno run. Nevertheless, it seems apparent that the Hellephant actually produces more than 1,000 hp and is nearer the 1,100 hp mark.

We don’t know what the owner of this Demon plans to do with the car, but are hopeful they will put it through its paces at the drag strip. It’ll be interesting to see just how much quicker it is than a standard Demon with its 6.2-liter supercharged V8 that is capped at 840 hp.
