Check out this wicked cammed and blown 2012 Chevrolet Camaro SS working out on the dyno with impressive results.
This week’s Dyno Blast video features a 2012 Chevrolet Camaro SS stretching its legs on the rollers. This Camaro SS has a 6-speed manual transmission, so it is an LS3 model with 426 horsepower. However, the V8 in this 5th gen Chevy muscle car has a few power-adding goodies under the hood.
First off, the LS3 features an “HPA Blower” custom cam, and headers, along with an Edelbrock E-Force supercharger. Immediately prior to making this run, the folks at HorsePowerAddicts added the Alcohol/Methanol injection setup. The numbers afterwards are impressive, to say the least.
We can hear the Edelbrock supercharger whining from the engine bay and when the driver gets to the proper gear. As the run ends, the cameraman moves from the front of the car to the dyno screen, revealing figures of 687.17 rear wheel horsepower and 602.07lb-ft of rear wheel torque. This comes with roughly 12 pounds of boost.
Assuming a conservative drivetrain loss ratio of 18%, this cammed and blown Camaro SS is making somewhere in the area of 838 horsepower at the crankshaft – an improvement of better than 400 horsepower with the cam, headers, blower and meth kit. Those are some solid numbers which likely make this a pretty stout car on the open road, but this cammed and blown LS3 also sounds great so crank up your speakers and enjoy!
"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.
