Witness The Hennessey Venom F5's Furious 1800bhp V8 Being Dyno Tested

Hennessey has released dyno testing footage of the V8 which will power its 300mph F5 hypercar

Remind me later

Want to hear the sound of 1792bhp being explosively developed at 8000rpm? Click the play button above. Preferably after plugging in some headphones.

The noise you’re hearing is generated from a General Motors LS V8, heavily modified by Texan tuner Hennessey. Although perhaps ‘heavily modified’ doesn’t quite cut it - little is carried over other than the basic architecture.

The F5 hypercar’s engine uses a custom block, along with new pistons, connecting rods and a fresh crankshaft. An unusual intake manifold meanwhile positions the intercooler between the plenum and the high-flow cylinder heads. This reduces the temperature of the air exiting the turbochargers before it goes into the combustion chamber, which means more air density and a better bang.

The two ball bearing turbochargers, by the way, have 3D-printed compressor housings. They’re cranked up to 23 psi, helping the 6.6-litre V8 achieve that ridiculous, near-2000bhp output, along with 1193lb ft of torque.

What you have to bear in mind, is this colossus of an engine will be propelling a car that Hennessey claims will weigh less than 1400kg. Raw speed will not be a problem for this car.

The F5 may have been beaten by the Chiron Super Sport in the race to 300mph when it hit 304mph at Ehra-Lessien, but we wouldn’t want to bet against Hennessey’s creation going even quicker.
