2010 Chevrolet Camaro SS: On The Dyno Rollers
October 01, 2009
You knew it was only a matter of time before we strapped down our long-term 2010 Camaro SS to the Dynojet rollers. There are nearly 5000 miles on the big silver lunchbox's odometer, and what better way to celebrate than a dozen wide open-throttle pulls to redline.
Yes, it took several runs for the power to reach a stabilized result but once it was in the zone, it remained fairly consistent from run to run.

As always, the best fuel in our area is 91 octane, but the Camaro's big, understressed 6.2-liter LS3 V8 probably doesn't care too much about frivolities like octane.
MD Automotive's Dynojet chassis dyno was used for this test, and SAE standard correction applied.
No real suprises here aside from the dips in the power delivery at 3200 and again at 4300 rpm. They're fairly pronounced and were repeatable, run after run.
Peak power at the wheels is 370 hp arriving at 6000 rpm, while torque peaks at 343 lb-ft at 5000 rpm. That's about right considering the Camaro generates 426 hp at the flywheel--GM definitely didn't under-rate the claimed power output.
Having 300 lb-ft at your disposal at just 2000 rpm looks great on the dyno chart. However, the Camaro's tall gearing and massive curb weight dull the LS3's low-end snappiness. Still, there's plenty of sauce here, especially for the price.
