Dyno-might: Dragtimes gets the numbers on the LS3 Corvette
First up was the 6-speed auto. It returned a plot that showed peak horsepower of 370.8, with torque at 363.8 ft-lbs. With a drivetrain loss of about 16%, that is spot on. Next up was the 6-speed stick. It came back almost 20 hp better than the slushbox. The numbers were 389.5 hp and 377.4 ft-lbs of torque. That shows about a 10% loss for that engine/transmission combo. Even better.
And then, just for kicks, LG added "longtube headers, performance cam, ported intake, K&N aircharger, under-drive pulley and a custom tune" and got a quick boost of more than 100 hp at the rears. That car now shows 506.7 hp and 457.1 ft-lbs... at the wheels! One of the best performance for the dollar bargains on the planet, this '08 Corvette seems ready to take on the world.
