Do we need somebody to point out the difference between a factory stock Dodge Challenger Hellcat and one that has gained 150 ponies?
Of course, we don't, but do we want to see it? Hell yes, and thanks to Hennessey, we can now show you how adding an average mid-size car's output to your Hellcat will influence the performance.

The piece of footage at the bottom of the page bring us a Hellcat-to-Hellcat comparo, one that involves a 707 hp Mopar machine and an 850 hp Hennessey Dodge Challenger Hellcat.

This isn't the first time when the Texan tuner brings a Street Fighter take on such a matter, but, frankly, the theme seems to be ageless - after all, the original arcade game that served as an inspiration for this stunt is now three decades old.

What happened during the 850 hp Hennessey Dodge Challenger Hellcat's gym session?

So, how are the extra horses achieved? The 6.2-liter supercharged V8 gets a lower pulley upgrade, which adds 1-2 psi of boost, while the throttle body is a port-matched unit and the standard air filter is replaced with a high-flow one. Oh, and let's not forget the ECU remap that keeps everything in check.

Heck, the Hellcat itself is quite the opposite of "reasonable", so it would be odd to call this upgrade so. However, the output and the changes mentioned above do seem reasonable when compared to the Lone Star State developer's 1,000 hp Hellcat package.

No, we're not talking about the supercharged upgrade the tuner offers for the SRT beast. Instead, we're referring to the one that sees the factory blower joining forces with a pair of turbos, for the ultimate bragging rights muscle effort. For the record, both offer 1,000 hp.

Returning to the Street Fighter piece we have here, be prepared to see plenty of burned rubber being treated as collateral damage.
