Pretty impressive video. Looks like the car has a enough power to take it higher, however it’s being limited by the cars gearing and extra downforce.

Chevrolet has finally taken the lid off the Corvette ZR1’s power ratings, and boy are they staggering: The 2009 Corvette ZR1 will make 638hp (that’s 13 less then a Ferrari Enzo! 26 MORE than a Porsche Carrera GT!) and 604 lb.-ft of torque, with a top speed of over 200mph. Not only that but the new ZR1 is to be the single most gas efficient 600hp motor in all of the automotive world, getting 26mpg (source: Popular Mechanics) on the highway.
Track times and acceleration numbers have yet to be released.
The ZR1’s world domination can now commence.

Quick note: GMNext.com is hosting a live chat with chief Corvette ZR1 engineer Tadge J. Juechter on Tuesday, April 29th 2008, from 3:00pm to 4:00pm EDT. Participants will get a chance to discuss “the history of the ZR1 and the legacy it leaves on the road.” Chat is to presumably cover both the C4 and C6 ZR1 models.
Transcripts will be available after the chat.
I came across a pretty old blog posting at GMblogs.com and found this pretty interesting: The LS9 motor in the new Corvette ZR1 is making 300hp by 3,300rpm and 320 ft-lbs of torque at only 1,00rpm! Needless to say, those are truly amazing numbers.
Our Powertrain team’s testing shows the LS9 makes about 300 horsepower by only 3,300 rpm and a significant 320 lb.-ft. of torque at only 1,000 rpm. The engine’s rev range is competitive with many overhead-cam engines, but we’ve also got usable torque at every notch on the tachometer. It’s a also a compact, relatively low-mass package, which helps the ZR1 achieve a better power-to-weight ratio than the Porsche 911 GT2, the Ferrari 599 and the Lamborghini LP640.
The max torque for the ZR1 is around 600 ft-lbs, with 620+hp.
Edmunds has some awesome new video footage of the ZR1 lapping the ‘Ring. Their reporters are claiming lap times in the low 7:40s; a number that is sure to drop in the mid to low 7:30s. However, those times are still a ways off of Chevy’s goal of setting the Nurburgring production car lap record.
According to our shooters on the ground, the Corvette ZR1 was turning in lap times in the low 7:40s, a pace that puts it right up there with the world’s fastest supercars. And given the damp conditions and rough, hand-timed numbers, you can expect to see even quicker official lap times when Chevrolet goes public with its Nürburgring data.
…That said, the folks at Chevrolet aren’t worried about the performance potential of their $100,000 halo car. According to ZR1 Chief Engineer Tadge Juechter, the ZR1 will beat the track record for production cars at any road course in the world.

I decided to use a 1/4 mile calculator to estimate the ZR1s potential in the 1/4 mile. Using a 3400lbs car weight and 620hp (flywheel), I came up with a 10.82 ET. For a test in accuracy I punched in the numbers for a C6 Z06: 3200lbs car, 505hp: 11.36. Those calculations are almost identical to real life considering that the C6 Z06s are consistently running 11.2-11.4s (stock with street tires) in the quarter.
Some of my calculations put the ZR-1’s 1/4 mile time in as low as 10.6. Obviously we can’t factor in traction issues, but I’m willing to bet these numbers aren’t far off.
THE 1/4 mile NUMBERS (ESTIMATED ZR1 TIMES):
1/4: 10.8@133mph (conservative)
1/4: 10.6@136mph (liberal)
Side note: I guarantee you that no magazine is going to get the ZR1 down the 1/4 mile in under 11 seconds. Most magazines generally make a mockery of the true acceleration numbers for performance cars. Just look at Edmunds, they managed a 12.1 in the C6 Z06.
