Hennessey Reveals HPE1000 Challenger SRT Super Stock

Video / Comments

But it's not as crazy as we hoped.

Hennessey Performance is no stranger to insane horsepower. The tuner has built a McLaren 765LT with 1,000 horsepower and is working on putting a 1,000-hp Hellephant motor in the Ram TRX too. Clearly, Hennessey knows how to build a car with four-figure horsepower ratings, but for some reason, not all of its tuning upgrades are as impressive as you might think. For example, a Ram TRX can be fitted with a Mammoth 1000 package, promising 1,012 hp, yet dyno results show figures in the region of 760 hp. Now, the tuner has released a test drive and dyno run video of its HPE1000-equipped Challenger SRT Super Stock and the results are once again underwhelming.

Before we get to the actual dyno run, the video shows a test driver going for a rip in the modified Challenger SRT Super Stock and it looks like a lot of fun. Hearing that supercharger whine as the car accelerates is addictive, but what kind of figures can you expect with this package?

As standard, Dodge claims 807 hp and 707 lb-ft of torque, with these figures measured at the crank. Hennessey strapped the car to its Dynojet before tuning it and recorded at-the-wheel figures of 700 hp and 648 lb-ft of torque. After the HPE1000 package, the car produced 810 hp and 732 lb-ft at the wheels, increases of 110 hp and 84 lb-ft, respectively.

That's still an impressive jump in performance, but it does make us question the validity of Hennessey's claims if a package that is meant to provide 1,012 hp can't even get close to that. Sure, you get far more power than you need and this modified version of the Super Stock is surely capable of more than a standard model, but with the company working on producing a hypercar of its own design that could break the 300-mph barrier, guesswork has no place here. Hopefully, when the Venom F5 finally drops, it will live up to the promises Hennessey has made.
