A 1998 Corvette with a stroked LS1 topped by a supercharger lays down almost 920 horsepower at the rear wheels.
This Dyno Blast video features a 1998 Chevrolet Corvette in action on the rollers. This C5 Corvette has been built by the crew at HorsePower Addicts to create far more power than a stock ’98 Corvette.
In stock form, this 1998 ‘Vette would have packed 345 horsepower and 350lb-ft of torque at the crankshaft of the 350 cubic inch engine, yielding to somewhere in the area of 300 horsepower at the rear wheels after you factor in drivetrain losses.
This 1998 ‘Vette is powered by an LS1 stroker motor built by the HorsePower Addicts, which has been enlarged to 408 cubic inches. When that 408ci V8 is fitted with a supercharger, an upgraded fuel system, a meth injection kit and headers, the output is increased way beyond those stock numbers.
Way, way beyond.
In the video below, the blown and stroked LS1 Corvette is pushed to its limits on the rollers, starting with a simple cruise through the first three gears. Once the driver is in 4th gear, where he wants to be for the dyno pull, he puts the hammer down and lets the monster small block do its thing. Amidst the whine of the supercharger, the whoosh of the relief valve and the road of exhaust, the stroked Corvette clears its throat and lays down big power to the rear wheels and it sounds incredible while in action.
As the video ends, we get a quick look at the engine bay of this bright red C5 Corvette below the camera turns to the dyno screen. You can see peak numbers of 919.9 horsepower and 777.22lb-ft of torque at the rear wheels.
The swap from the naturally aspirated 5.7L engine to the supercharged 408 lifted the output of this C5 Corvette by about 600+ horsepower or 200%.
"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.
