A dying breed, the naturally aspirated 5.2-liter V10 available in the Audi R8 and Lamborghini Huracan is one of the most iconic engines ever developed. Some would say applying forced induction is sacrilegious as the supercar from Ingolstadt loses some of its charm for the sake of more power. However, there are people out there who consider 562 horses are simply not enough. For that segment of the market, tuners are offering R8 twin turbo and supercharger conversions to take the mid-mounted engine to staggering levels of power.
Hennessey is among those tuners, offering its HPE900 R8 package with a twin-turbo package. The Texas-based aftermarket specialist recently installed its kit on a 2020 R8 Spyder in the base configuration rather than the 602-hp Performance model. A stock output of 562 hp and 406 lb-ft (550 Nm) at the crank is nothing to sneeze at, especially for a “base” version, but Hennessey would argue there’s always room for more power.
A timelapse video of the tuner’s R8 Twin Turbo conversion culminates with a dyno run of the supercar, now generating some jaw-dropping output numbers. It produced 752 hp and 545 lb-ft (739 Nm) at the wheels while still feeding on pump gas. Not only that, but it has the stock engine, transmission, and fuel system. Hennessey says the car actually behaves like the standard naturally aspirated R8 right up until the pair of Precision turbos kick in.
Hennessey’s product page for the HPE900 R8 package mentions the V10 produces a whopping 912 hp at 7,400 rpm at the crank and enables the car to hit 60 mph (96 km/h) in 2.6 seconds. The quarter mile is completed in 9.8 seconds at 145 mph (233 km/h). Needless to say, the kit can also be had for the Audi R8’s Italian sister from Sant-Agata Bolognese, the Huracan.
