Sorry Viper fans… You’re too slow for the Hellcat

Sorry Viper fans… You’re too slow for the Hellcat

With the release of the 707 horsepower Hellcat, it’s no wonder Viper fans are a little pissed. Think about this for a second: 707 horsepower Vs 640 hp. That’s the comparison being made right now between the 2015 Dodge Challenger SRT Hellcat and the Dodge SRT Viper.

You got it right; a supercharged V8 is now more powerful than a naturally aspirated V10. It seems only natural that the Hellcat V8 would be put into the engine bay of Chrysler’s flagship supercar. Unfortunately, it’s not technically possible. Why? The first and most apparent reason is that the dimensions of a Hemi simply won’t fit under the Viper’s hood.

If the automaker was to modify the Viper’s hood line so the 707 horsepower V8 could fit, it would severely alter the Viper’s aerodynamics.

Need another reason? The Hemi is too wide and it won’t clear the Viper’s chassis rails. As if this wasn’t bad enough, there would also be a problem with the exhaust manifold and supercharger hardware, which add to the dimensional problem. The supercharger that powers the massive V8 also runs on a separate cooling loop. This is a whole other big issue to overcome.

While the automaker has squashed every hope and dream of getting the supercharged hemi in the the viper, SRT Powertrain Director Chris Cowland expects that “somebody will do it (the engine switch). It won’t be us.” Enthusiasts are now just waiting to see which aftermarket tuner will be the first to successfully do that Hellcat-Viper engine swap.

Viper fans can be rest assured that the Viper is expected to receive a slight power bump for 2015.

The power boost of the 8.4-liter V10 will reportedly produce 645 hp. Torque will remain the same at 600 lb-ft. This was done in order to better prepare the Viper for its upcoming fight against the new Corvette Z06, which has 650 ponies.
