Speed = WRX STI engine + ATV

With over 3,000,000 views chances are a few of you have seen this video. Until today, I had not.

300+ horsepower is a lot of power in just about any vehicle but when you put that kind of power in an ATV you're unstoppable...unless you fall off.

Ken Brough from New Zealand wanted to compete in New Zealand’s Race to the Sky hill climb so he built a custom ATV powered by a 2.0L turbo-charged 4-cylinder engine pulled from a Subaru WRX STI

Unfortunately the STI ATV didn't comply with regulations for the race so it was never entered but Ken certainly has fun with it anyway.
