How did this guy creat a 6second 1/4mile 2000 horsepower mustang?

haha, that guy has a race-specific engine, transmission, and rear end. if you got 10k, rebuild the engine with forged internals, upgrade your fuel system and slap on some twin turbos. you may make around 500-600hp on this. but you will also need to upgrade your , and rear end after this.
