Hennessey GTR 700 !!

You name it and John Hennessey will make it faster. From Vipers to Vettes to Challengers, Hennessey Performance will take competent sports cars and make them into tire-shredding speed demons with more horsepower than any street-going vehicle should ever logically have. The latest creation to come from the Texas tuner is the GTR700 based on the Nissan GT-R. The upgraded Godzilla now sports 715 horsepower and 662 lb-ft torque thanks to numerous modifications including a stainless steel exhaust system, new ECU programming, modified turbos with larger compressor wheels, 100mm cold air intake, high-flow fuel injectors, transmission cooler, clutch pack upgrades, and more. The result is stupefying. Sixty mph comes up in just 2.8 seconds, 100 mph in 6.7 seconds and 150 mph in 14.5 seconds. Compared to a stock GT-R, the GTR700 reaches 186 mph in less than half the time.
