C7 Corvette Gets Dyno Tuned: For Once, This Really is a “Tune Only” Car

By -

Watch a 2016 Chevrolet Corvette with nothing more than a custom tune make solid numbers on the dyno.

The C7 Corvette is powered by the new LT1 V8, delivering 455 horsepower and 460lb-ft of torque (460hp and 465tq with the performance exhaust setup). A stock C7 Corvette Stingray packs between 395-420 horsepower at the wheels, depending on a handful of variables including temperature, altitude and the individual dynamometer itself. Figure that “around 400 wheel horsepower” is a good estimate for a stock C7 Stingray.

So, what can a stock C7 put down when the engine computer has been tuned to squeeze a little more power out of the LT1 V8? To be exact, this C7 Corvette laid down 425 horsepower and 425lb-ft of torque at the rear wheels, so assuming the average wheel horsepower rating of 400-ish, this particular Stingray picked up somewhere in the area of 25 wheel horsepower from just a tune.

Figure that if the fully stock C7 Corvette Stingray with the automatic transmission makes around 400 wheel horsepower, it is burning up about 60 horsepower between the crankshaft and the wheels – accounting for a drivetrain loss ratio of about 13%. If we apply that 13% loss ratio to this Corvette, 425 wheel horsepower and 425lb-ft of wheel torque would equate to roughly 488 horsepower and 488lb-ft of torque at the crankshaft, so with nothing more than an engine computer tune, this Corvette gained close to 30 horsepower and 25lb-ft of torque.

Finally, in addition to showing us what kind of power a C7 Corvette Stingray can gain from just a tune, this video gives us a great chance to hear the LT1 roar, so crank up your speakers and enjoy!
