2017 Chevrolet Camaro ZL1 heads to the dyno

Follow Jeff

The 2017 Chevy Camaro ZL1 is a monster. It's already proven itself by setting a sub 7:30 lap time on the Nürburgring. That was achieved in part due to the supercharged 6.2-liter V-8 under the hood. It's the LT4 that also powers the Corvette Z06, and in the Camaro ZL1 it produces 650 horsepower and 650 pound-feet of torque. Does it really though? A man with the appropriate Instagram handle of @zl1_Tommy is prepared to find out.

In this video, we can see that a new Camaro ZL1 is strapped to a dyno at the Houston House of Power tuning shop. The results? A best horsepower figure of 554 and a best run for torque output shows 532 lb-ft. If we account for the typical 15 percent drivetrain loss, and add in the fact that this car is equipped with an automatic gearbox, we're pretty close to the advertised numbers. Those two figures translate to 638 horsepower and 612 lb-ft of torque at the engine if this dyno output is showing wheel horsepower.

That's not quite as good as the Z06 has done at the dyno. The LT4 in the Z06 has outperformed the figures quoted by General Motors, and by a fair margin. Is the 10-speed automatic sapping a bunch of the power from the engine by the time it gets to the wheels? We'll need to see a dyno run of a car equipped with the 6-speed manual to really find out.

In the meantime, you can just sit back and enjoy this video of John Hennessey showing just how fast a ZL1 will get up to 173 mph:
