Dear Internet,

It's official. I've now seen it all.

I thought I had when the original Jeep Grand Cherokee SRT8 came out several years ago. It turns out I was wrong. That rig's 420 horsepower was staggering for the time, but it pales in comparison to the figure pumped out by the creation in the video below, which you so graciously hosted. Even the modern GC's 470-horsepower 6.4-liter V8 seems "normal" compared to the numbers in the clip. Thanks?

Spankin Time Motorsports used the WK-platform Grand Cherokee SRT8 as a starting point for one sick SUV. The tuner then threw out its 6.1-liter HEMI, replaced it with a 7.0-liter stroker and added a Kenne Bell supercharger. Huffing 18 pounds of boost, the modded monster puts down 870 horsepower to its drag radials.
