This Is What A 1,000-HP Hellephant-Powered SRT Demon Sounds Like

In a planet more and more preoccupied with squeezing each individual ounce of performance out of the inner combustion motor, redefining “normal” to conjure downsizing and turbocharging, low-viscosity lubricants, lighter-duty internals, it is oddly refreshing to know that Mopar’s brutish “Hellephant” crate motor exists. Displacing a whopping 426 cubic inches – or seven. liters – with cast pistons, a large-raise cam, and a large 3.-liter twin-screw supercharger, the Hellephant is the 1,000-horsepower response to the question: “What happens when the engineers just take items too much?”

Gearheads ate up the response, as in spite of a whopping $30,000-or-so starting up price, Mopar’s overall run of hand-crafted Hellephant crate motors sold out within two times.

Now, we’ve found the Hellephant in motion and found out if it can reside up to the 1,000 hp statements on its initial dyno run.
