Hennessey Performance teases world’s first C8 Corvette twin-turbo

In December last year, famous Texan tuner shop Hennessey Performance promised us to boost the eighth-generation Corvette all the way up to 1,200 horsepower (895 kW). These two videos show their first bits of progress towards that goal.

Aside from the dual turbochargers, the LT2 V8 gained new pistons and connecting rods forged from a particularly rigid aluminum alloy, a compression ratio of 10:1, a number of transmission improvements, and Brembo brakes.

As a result, the output rose from the 466 hp (347 kW) and 611 Nm (450 lb-ft) of torque to 643 hp (479 kW) and 772 Nm (569 lb-ft). What makes it even more spectacular is the fact that the former values are provided by the manufacturer based on the net engine output, while the latter ones are based on actual dyno measurements at the wheels. Therefore, the net output of the new V8 should be closer to 740 hp (552 kW) or so.

The promised numbers may be a fair distance away, but the intermediate results are quite impressive nonetheless!
