Texas-based efficiency tuner and hypercar maker Hennessey Efficiency has rolled out a 1000 hp improve bundle for the Cadillac CT5-V Blackwing.

The Cadillac CT5-V Blackwing is powered by GM’s supercharged LT4 V8 engine. The 6.2-liter small-block places out 668 hp and 659 lb-ft of torque. It’s mated with both a 6-speed handbook or a 10-speed computerized.

The H1000 bundle contains ported cylinder heads, enhanced consumption and exhaust valves, improved lifters and pushrods, outsized warmth exchangers, and long-tube chrome steel headers. The inventory supercharger is changed with a high-flow unit and receives the Hennessey Engine Administration Calibration (HEMC).

The ultimate result’s 1000 hp and 966 lb-ft of torque, leading to a 0-60 mph time of two.5 seconds (a second faster than inventory) and a high velocity of 200 mph. Hennessey claims a quarter-mile time of 10.1 seconds.

As with most improve packages from Hennessey, the H1000 bundle comes with a 2-year / 24,000-mile restricted guarantee.
