With 755 hp (563 kilowatts) directly from the factory, the Chevrolet Corvette ZR1 is already one of the most powerful streets you can buy today. Someone familiar with Hennessey Performance knows that too much is not enough for the Texas tuner, so the video above shows that a white ZR1 generates 905 hp (675 kW) on a dyno. While the number is impressive, we dare to take all the octane-blooded petrol heads out of the way to get tremors listening to this loaded LT5 engine that bellows out its 6,800 rpm song. Seriously people, find the best sound system you can and turn the volume up far up .
Now that we say 905 hp, remember that this is measured at the rear wheels . A layer of Corvette ZR1 generally produces about 655 hp (488 kW) on the deck, and in fact, this actual car generated pretty much the exact figure as a baseline drive. This means that the higher-power pushrod engine in this dirty sound “Vette actually produces well over 1000 hp (746 kW), which is the first HPE1000 ZR1 to come out of the tuning store.
Unfortunately, we do not know exactly what is involved in creating this monster machine. A video from Hennessey earlier in April showed that the car made 715 hp (533 kW) on the wheels with only one upgraded cold air intake and one engine song – an improvement of 61 hp from the storage vehicle. Presumably, jumping at nearly 200 horsepower jumps more hardware changes and further increases, and the exhaust completely releases freely on this set machine.
Corvette ZR1 is the Chevrolet swan song for the iconic fresh American sports car. On July 18, the automaker is ready to reveal the next-generation C8 Corvette, which we all know by now will move the engine to the center of the car for the first time in the model’s history. It was originally thought that the Chevrolet would continue to build Corvette’s tributary to the side of the engine’s model for at least a while, but it no longer seems like that was the case. At least it goes out with a huge blow.
