Some years ago Ricard Hammond tested a Shelby GT500 and since he had a dyno machine available he put it there and arrived at 447 hp. That’s enough fun to be honest, but since it’s called GT 500 a lot of guys always tend to tune it up to 500 hp and beyond, which is fine but be cautious! This dude in this video had its engine tuned to 800 hp, and, well, as you will see it just explodes on dyno. Just imagine that happens as you set off in a drag race, what a spectacular sight!
