AMS Performance Alpha Omega-12 Nissan GT-R

In theory, building a unlimited street-legal race car is pretty simple. You add parts to boost horsepower, run until something breaks, fix it and repeat. In practice, massaging machines up to 2,000 hp out of regular production models requires years of dedication and a high level of engineering expertise — which is why head-up racing events like the Texas Invitational often feature the same handful of shops battling for top prizes.

Last weekend, the fall Texas Invitational held its King of the Streets competition that drew 42 of the highest-power Lamborghinis, Vipers and Nissan GT-Rs available. This year's winner: the Alpha Omega GT-R of AMS Performance, driven and built by Ivan Phipps, featuring at least 2,000 hp from the 3.8-liter twin-turbo V-6, enough power to set a new 1/4-mile record for a GT-R at 7.7 seconds/186 mph.
