SEMA: Chevrolet Cobalt Time Attack
<img src="https://www.cobaltss.net/articles/sema3.jpg" align="left" border="0" hspace="5" vspace="5">To turn a street machine into a track racer you need the right pedigree: a hot, lightweight performer with plenty of handling capabilities, and a team of battle-tested racing engineers to make it happen. That explains why Chevrolet and GM Performance Division have taken the sizzling Cobalt SS Coupe Supercharged coupe and turned it into an Unlimited Class Time Attack machine, which already bested the legendary Nissan Skyline’s times by seven seconds in Street Tuner Challenge’s Time Attack on July 21.
The premise behind Time Attack is to take a street vehicle and – using tires that are legal on public streets – turn in the fastest lap on a racetrack for the vehicle class. The vehicle must be from a model originally produced for legal street use and it must have a silhouette largely faithful to the original.
Because Time Attack challenges involve multiple runs, the engine must be powerful and durable. The Time Attack Cobalt SS Supercharged coupe’s Stage 2+ Ecotec engine is certainly up to that challenge. Developed by GM Performance Division and GM Powertrain, it features an Eaton M-62 Gen 5 Hybrid supercharger and delivers 264 horsepower at 7000 rpm and 230 lb.-ft. of torque at 4000 rpm. When nitrous boost is added, performance jumps to 344 horsepower at 6800 rpm and 350 lb.-ft. of torque at 3600 rpm.
Because weight is the nemesis of performance, many of the production Cobalt elements have been replaced with carbon fiber counterparts. These include the fenders, hood, doors, roof, decklid, spoiler, side splitters and Sparco car seat. The vehicle’s glass has also been replaced with Lexan, and interior trim has been kept to a minimum. The result is a vehicle that weighs a mere 2,350 pounds.
Inside, the Time Attack Cobalt SS Supercharged coupe incorporates safety systems per National Auto Sport Association (NASA) race rules, including a full roll cage, side net and fuel cell. It also features a full complement of race gauges, as well as a Sparco race steering wheel and GM Accessories pedals.
The Time Attack Cobalt SS Supercharged coupe runs in NASA’s Unlimited class, which includes FWD, RWD and AWD vehicles. Following SEMA, it will race on Nov. 8 at Buttonwillow Raceway Park in central California – the same track where it beat the best times of an 801-horsepower AWD, twin-turbo Nissan Skyline and a nitrous-charged Volkswagen Jetta.

Just found the "Time Attack" race results from the Nov 8 Race at Buttonwillow Raceway. Against 50 other cars the Cobalt SS won. Looks like there were 10 FWD cars,18 AWD cars and about 21 RWD cars. Also well known D1 hot shoes like Sam Hubinette, Ken Gushi, Calvin Wan, Alex Pfieffer, Taka Aono, Hubert Young and James Chen were driving against John Heinricy in the Cobalt SS. The only American cars were Heinricy"s Cobalt SS, a NEON SRT4 driven by Hubinette and a Mustang driven by Gushi. The SRT4 finished 17th and the Mustang (a Drift car) finished 44th. here's a link for anyone interested. Sorry I can't yet post on Front Page News.

GM might have very deep pockets , but nothing on the time attack , or the ga cup cars , is top of the line engineering , other than pcm programing , and they are still having issues with that , since they are running very to the same programs that the production cars use
because of the drive by wire stuff
all i say is let the little baby ricers cry

WOW! So does this mean that with our current engine set-up we can add the stage-1 Stage 2 kits when they become available, add exhaust kit and then throw down a nitrous kit and not harm the motor without re-inforcing anything? Does anyone know what nitrous kit they used, *Dry vs. Wet vs. direct* and if they did anything other than the stage kits to the stock 2.0L SS/SC engine?

The timeattack series is re running on the speed channel for the cobalt ss if anyone is interested. Last night the show was all about tearing the engine down. Seeing our motor on a hoist and seeing the internals was really impressive to me. It can easily handle up to 400 hp with those internals.
