In standard guise, the current-generation Nissan Z is a fairly quick car courtesy of its twin-turbo 3.0-liter V6 that pushes 400 horsepower to the rear wheels. Thanks to the grease monkeys over at AMS Performance, who are known to chase quarter-mile records through aggressive turbocharging, we now know that there's even more potential to be had from the brand's VR30DDTT.

Just earlier this week, the tuning house got the Z to produce a peak power output of 440 hp, but now it's claiming a figure of 500 hp at the wheels thanks to some good old-fashioned bolt-on upgrades and ECU recalibrations.

With this result, AMS claims that its revision will allow the Japanese sports car to run a quarter-mile in 11.43 seconds at 124 mph. This is compared to a stock model tested by Hagerty that crossed the quarter-mile line in 12.3 seconds at 116 mph.

So, how exactly did AMS pull this off? The mods fitted to this Ikazuchi Yellow unit consist of a fully custom and in-house developed exhaust system with downturns, a prototype heat exchanger, an intercooler, and a 100-octane ECU tune. This power was put down to the ground effectively thanks to the use of 28-inch Hoosier D06 drag-specific tires on the rear axle.

Considering that the Z uses an ICE unaided by an electric motor together with a six-speed manual transmission, this time is nothing to take lightly. Its older sibling, the R35 Nissan GT-R, claims to use its twin-turbo 3.8-liter V6 pushing 565 hp with a more efficient dual-clutch automatic transmission to run a claimed time of 11.2 seconds.

Of course, we have to wonder whether Nissan is looking at this and pondering whether performance should be increased in-house as an official manufacturer-spec product. We're well aware that the brand is planning a performance-enhanced Nismo model but traditionally these variations never have a massive power bump over the stock models, so a factory 500-hp Z may still be a fleeting dream.

The track-only Nismo GT4 revealed to us late last month is considered to be a preview of this edition, but no claimed figures were disclosed. We are aware that the VR30DDTT under the hood is packing more of a punch.

Although 500 hp is a pretty impressive figure in the world of ICE sports cars, it's apparent that AMS isn't done with shortening its times. It states that on the day of testing, the cold and unprepped surface coupled with the drag radials made the launch more of a challenge. It confirms that another power increase is in the pipeline and that a return to the strip with better climate conditions is imminent.
