The 2016 Dodge Challenger Hellcat is known for one thing – horsepower. The company claims that it makes 707 horsepower, but that’s at the crank and at sea level. So how much would it make in mile-high Colorado at the rear wheels?
For the latest episode of Hellcat VS., the Challenger is at The Boost Creep in Longmont, Colorado to see just how much power it puts out at the rear wheels.
Owner Harvey Epstein guessed that the Hellcat would make about 620 horsepower at the rear wheels. At altitude, a naturally aspirated car would lose about 30 percent of its power, but Epstein said that because of the supercharger on the Hellcat engine, it would only lose 15 percent.
The dyno used at the shop is made by Dyno Dynamics, a company out of Australia. The dyno used for the test is about 10 years old.
The Challenger Hellcat comes with two keys. The black key limits power to 500 horsepower, while the red key unlocks the full 707 horses. For the test, the red key was used, which should unleash the engine’s full power.
Roman guessed 600 horsepower at the rear wheel for the dyno test. What do you think it will make?
