Depending on your needs, Hennessey Performance can upgrade a ZL1 from between 650hp to over 1,000hp.

First up, the HPE650 features a supercharged 6.2-liter V8 engine that has been equipped with a cold air induction system, stainless steel headers and an upgraded intercooler. There's also new pulleys and a revised ECU. Thanks to these modifications, the engine produces 658 hp (491 kW / 667 PS) instead of the standard 580 hp (432 kW / 588 PS).

The HPE700 includes all the aforementioned equipment as well as a new camshaft and high flow cylinder heads. This enables the engine to produce 707 hp (527 kW / 717 PS).
Customers can also order the previously announced HPE800 and HPE1000 packages which produce 800 hp (597 kW / 811 PS) and 1,021 hp (761 kW / 1,035 PS), respectively.
