Edmunds Dynos the 2012 Corvette ZR1 and the 2013 SRT Viper GTS

Edmunds Dyno Tests the 2012 Corvette ZR1 and the 2013 SRT Viper GTS

We already told you that the folks over at Edmunds.com recently matched a 2012 Corvette ZR1 against the new 2013 SRT Viper GTS in one of their Burnout Super Tests.

The Corvette dominated that competition, laying down a record-setting black stripe of more than 514 feet, nearly 100 feet longer than the Viper managed.

Now, Edmunds decided to take the 2013 Viper to the MD Automotive Dynojet chassis dyno to see what it could do.

Well, the Viper did put up some impressive numbers, compared to ordinary cars, but when it went up against the extraordinary ZR1, well, let’s just say the King is still the King.

On the dyno, the Viper used its massive 8.4-liter pushrod V10 to send its torque rising steadily to a maximum of 528 lb-ft at 5,100 rpm. It reached its maximum horsepower of 558 just before the abrupt 6,400-rpm fuel cut. We couldn’t find the exact numbers for the Corvette, but from the accompanying chart, it appears that the ZR1’s horsepower was still climbing to nearly 600 as the rpm’s headed toward 7,000.

But this is one of those cases where the peak numbers definitely don’t tell the whole story, says Edmunds, which adds, “Though the Viper enjoys 2.2 liters more displacement, it just can’t ingest as much air as the ZR1′s blower heaves through its valves.”

That makes for a big difference in torque through the midrange between the two supercars. For example, at 3,600 rpm, the ZR1 was producing 85 lb-ft more torque than the Viper.
