The good people at SRT take a Dodge Hemi V8—already a potent engine in its own right—then rework nearly every component to make it tougher. Then, like a glorious but barren cake, they top it with a supercharger larger than the sovereign nation of Lichtenstein, one that can suck the air out of an average room in less than 10 minutes.
The 707 hp that results produces a ton of heat, so to ensure it doesn't literally melt itself, Dodge employed so much advanced engineering that the materials used actually have more in common with a Russian nuclear submarine than a 1960s Hemi. Really. So yeah, that's why my instructor was so emphatic about a cautious application of throttle.
Once you fire it up, though, it sounds like the Three Tenors being fed through the jet turbines of a F-15 Eagle, and the engineer-speak becomes merely academic.
