Watch a 2014 Corvette Stingray Z51 Benefit from a ProCharger Setup.
This week’s Dyno Blast video features a 2014 Chevrolet Corvette Stingray Z51 making a pair of runs on the rollers. On the first run, the 2014 Stingray Z51 is in factory-stock form with the 7-speed manual transmission and the performance exhaust setup. On the second run, this Stingray has been fitted with a ProCharger supercharger and two different tuning setups. Best of all, there is an interesting performance overlay, letting us watch the wheel speed, the engine RPM, the horsepower and torque levels and the line graph of the dyno run.
Figure that the 2014 Corvette Stingray with the performance exhaust setup makes advertised figures of 460 horsepower and 465lb-ft of torque at the transmission, but before adding the supercharger, the owner wanted to get a baseline readout. On the run in the video below, this C7 Stingray lays down 414 horsepower and 411lb-ft of torque at the rear wheels – giving this car a drivetrain loss percentage of right around 10%.
Next, the video shows this same Corvette Stingray with a ProCharger blower setup making a run with the street tune and 7psi of boost pressure. With that setup, this Corvette lays down 599 horsepower and 554lb-ft of torque at the rear wheels – improvements of 185 horsepower and 143lb-ft of torque at the wheels.
Finally, we don’t get to see the dyno run with the “power tune”, but we do get to see the dyno chart with evidence of 624 rear wheel horsepower and 570lb-ft of rear wheel torque – accounting for increases of 210 wheel horsepower and 159lb-ft of wheel torque.
This video offers those C7 Corvette Stingray owners considering a simple supercharger setup a great chance to see the package in action with impressive results and for the rest of us – it is just cool to see this before-and-after video with the vehicle information on the screen.
"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.
"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.
"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.
"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.
"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.
