Corvette LT4 Supercharged V8DETROIT – The all-new 2015 Corvette Z06 is the most powerful production car ever from General Motors and one of a few production cars available in the United States that delivers more than 600 horsepower.

 

The Z06’s LT4 supercharged 6.2L V-8 engine is SAE-certified at 650 horsepower (485 kW) at 6,400 rpm and 650 lb-ft of torque (881 Nm) at 3,600 rpm.

“The LT4 Small Block sets a new benchmark for power and torque at GM,” said Steve Kiefer, vice president, GM Powertrain Engineering. “The engine also puts the new Corvette Z06 on par with the most powerful supercars offered in America, while delivering performance with impeccable manners that make it suitable for daily driving.”

Watch the video, guess the power of the 2006 Dodge Charger in the V8TV Forum, and you could win a Predator Hand Held Flash Tuner from DiabloSport! The DiabloSport Predator is a hand-held tuner that can help you modify the tune of late-model cars, and it can now tune the Mopar Hemi powered cars. We recently shot a dyno session on a 2006 Charger at Finish Line Performance. Watch the dyno pull video, then log in on the V8TV Forum to guess the power level it made and you can win your own Predator Tuner!

 

 We recently visited Finish Line Performance in Naperville, IL, to check out their open house and see some killer cars. Finish Line Performance is not only a very reputable 2 and 4-wheel dyno tuning facility, but they also build everything from custom mandrel-bent exhaust, turbo, and intake systems to complete engines and restorations. We take a look at their turbo Dodge Magnum and the LS2 427 cubic inch Solstice... it's an animal. The grand total for the open house was over 240 cars stopping by to check out the action. Between pulls on their 4-wheel dyno, Dan Bills gave us the skinny on his new Mustang race car as well.

 

Weve come to realize that the sum of parts on Mike Riochs 1995 Pontiac Trans Am LT1 350 convertible is in need of a performance tune to make them all play together nicely, so we headed out to Finish Line Performance to meet with Dan Bills to get the job done.

 

After the Dyno tuning was completed at Finish Line Performance, Nick Scavo and Mike Rioch headed out to the drag strip to shave a few tenths off the 1995 Trans Am's quarter mile time.
