Hennessey’s Next GT-R Upgrades Previewed – World’s Most Powerful GT-R?

June 12, 2009 Comments off


Proving that it’s not only the Japanese that can put together a complete turbo and manifold upgrade for the Nissan GT-R, John Hennessey has released the following preview video on Youtube. It shows the Hennessey Nissan GT-R with a fairly decent sized pair of GT30R strapped to the side in a high mount configuration. Also as you can see, to match the turbos they’ve fabricated a custom stainless manifold, custom stainless dump pipes and fitted up a pair of external wastegates.

The high mount location means they can fit up some nice short intakes which should lend themselves naturally to higher performance. Each GT30R can flow enough air for 500hp so, with two of them, look out because we could soon be knocking on the door of four digit hp Nissan GT-Rs.

Road & Track Magazine have recently gotten to spend some quality time on the first proper performance test of the new Hennessey GTR600. They’ve performed a number of performance tests and managed to gather a good set of data points.

Along with that they’ve published up a full rundown of what exactly comes with the GTR600 kit and at what cost.
