I don't know how you define realistic, but even if it's not, a lot of us do daydream about BIG power in our little trucks. I remember a great Car&Driver project where they installed a second engine in the rear of a Honda CRX. They successfully doubled the horsepower with no drawbacks other than a little additonal weight and zero cargo room. My point is anything is possible and if this guy succeeds we all have one heck of an amazing option to think about in the future. If not, it was just a nice dream and a little laugh for some.
