Here is a great video from RoadTestTV of a 900 horsepower supercharged Corvette Z06 running an 8.56 @ 160 MPH at Palm Beach International Raceway. This superfast Corvette swapped it’s standard 6 speed manual transmission for a PowerGlide transmission allowing for amazing launch off the line.
The new SRT Viper was tested by Motor Trend against the Chevrolet Corvette ZR1 in a heads up performance comparison down the 1/4 mile and at Laguna Seca Raceway. Powered by a 640 horsepower 8.4L V10 the SRT Viper ran a 11.4 @ 128.7 MPH, which tied the ZR1. The ZR1 edged out the Viper at Laguna Seca Raceway running 1:33.99 vs the Viper at 1:35.77. For $141,990 as well as all of the hype we expected quite a bit better from the reincarnated Viper. The Ford Mustang Shelby GT500 with 662 horsepower is just a few clicks slower for under $60,000. We’re hoping to see some better real world numbers for the SRT Viper soon.
With a 5.8L Supercharged V8 pumping out 662 horsepower via only two wheels and a manual transmission, the 2013 Ford Mustang Shelby GT500 can be quite a handful to get off the line with a good launch. Here is a video demonstration of the launch control feature which allows the driver to select the appropriate launch RPM between 2,500 and 5,200 RPMs. After the launch RPM is selected the driver puts the car in 1st gear, keeps the clutch pedal in and floors the gas pedal. After the RPMs reach the selected amount the clutch is quickly released and the GT500′s electronics do the rest of the work attempting to modulate the power to keep wheel spin to a minimum.
We’ve got some real numbers for the all new 2013 Ford Mustang Shelby GT500 powered by a 5.8L Supercharged V8 rated a 662 horsepower. 5.0 Mustang and Super Fords put one on a DynoJet where it put down 609 horsepower and 609 ft-lbs of torque at the rear wheels. There were also some drag strip runs done where the new GT500 was running 11.6 @ 125 MPH, which is much quicker and faster than any of it’s nearest competitors, the Chevrolet Camaro ZL1 and Dodge Challenger SRT8 492. Take a look at the dyno graph and video below.
We attended the StreetCarDrags private rental on May 6th 2012 where we this 2005 Ford GT with a Heffner Pulley and Tune upgrade was racing heads up vs a 2008 Dodge Viper with Belanger headers, exhaust and a Mopar tune. The Ford GT was making 630 horsepower while the Dodge Viper was running 600 horsepower at the wheels. Reaction times and launches were pretty close with the Ford GT edging out the Viper with an 11.4 vs 11.6. Weather was pretty bad with a DA of over 2,000 so we expect both cars to perform much better with decent weather conditions.
The mod wars are on for the new 2012 Chevrolet Camaro ZL1 with Redline Motorsports running a 10.3 @ 134 MPH with some minor modifications. Since the motor in the ZL1 has been out in the CTS-V for a while, most of the parts were ready to go. This Camaro ZL1 has basic bolt-ons including headers, tune, cold air intake, camshaft as well as upper and lower pulleys to increase the boost from the stock blower. The car pulled an impressive 1.54 60′ time with an upgraded torque converter and Mickey Thompson Drag Radials. Take a look at the pictures, video and timeslip info below.

We’ve got some great video footage of a modified 2010 Cadillac CTS-V running heads up against a bone stock 2012 Nissan GT-R. The CTS-V which normally comes with 556 horsepower has been modified with a modified supercharger pulley to up the boost pressure, headers, full exhaust along with some cooling and tuning upgrades. We estimate the CTS-V picked up around 80-100 HP with the modifications. It’s a close race with the stock 2012 530HP GT-R edging out the CTS-V by just a bit with the CTS-V running 11.38 @ 122.71 MPH vs the GT-R running 11.19 @ 124.26 MPH.
