This tuner is one of the most famous tuners in America for the sole reason of tuning mainly American vehicles and really packing some power under all of those monsters hoods and also tuning some non-American supercars and hypercars from Mclaren and Porsche mainly.
They have done great jobs with all their past projects but this is the first time they work on an Audi, especially on an R8, and they really outdid themselves with this one too, packing more power than anyone expected under Audi’s hood and a lot of torque to play with on the roads, the car itself being also road-legal, using about the same system they have used on the Lamborghini Huracan, the output of that being even more visible than on the Huracan itself.
Hennessey Performance Engineering otherwise referred to as HPE or simply Hennessey has become substitutable with tuned American cars with banging power outputs. That’s as a result of the popular tuner is fond and became noted for tuning practically Detroit’s big 3 – Ford, GM, and FCA.
In fact, searching through Hennessey’s web site, you’ll notice that the majority of the names on its catalog are American brands – except for McLaren, the planned Porsche Taycan, and this, the Audi R8.
By all means, the R8’s default naturally-aspirated 5.2L V10 isn’t a slouch; the Performance Quattro version can make 612 HP (456 kilowatts) and 428 pound-feet (580 Newton-meters) of torque. These numbers can propel the R8 from 0 to 62 miles per hour (100 kilometers per hour) in only 3.1 seconds With a Hennessey’s HPE900 twin-turbo performance upgrade, however, the goal is to spice up the R8’s output to 912 horsepower (680 kW) at 7,400 RPM. This was done by adding 2 precision twin ball-bearing turbochargers. The video on top of this page shows the Hennessey Audi R8 on the dyno, that makes 752 horsepower (561 kW) on four wheels and 545 lb-ft (739 Nm) of torque at the rear wheels. Not bad. Not bad the least bit.
Hennessey says that solely 6 PSI of boost was applied to the R8 on the dyno and it still uses pump gasoline. The engine, fuel system, and transmission are all stock, as well.
By the way, Hennessey additionally offers the same HPE900 upgrade to the R8’s platform brother, the Lamborghini Huracan. There are not many details yet for this upgrade however, in fact, you can’t expect anything less from the Texas-based tuner.
