What we've here's a case of extreme horsepower, and all of it got here to the streets of Chicago. It’s pleasant for a chunk of avenue testing like this to take place at night while the streets are actually empty. With modified Nissan GT-Rs on hand, one with over 700hp the second with a few 800 ponies, in addition to a 600+ Corvette Z06 and a Porsche 911 turbo, matters certainly became, well, pretty damn loud. And speedy. Thanks to 1320video for this BAD*SS video. So which of these four is the fastest?
