Turbo LS-Powered Oldsmobile Cutlass Supreme Packs Monster Power

Turn-key Oldsmobile will get everyone’s attention, driving into the track and running 9s.

There was a point in time where General Motors cars from the mid-1980s were mocked for their lackluster performance, but cars like the 1984 Oldsmobile Cutlass Supreme have proven to be a great platform for a big-power build. The 1984 Olds shown here was recently listed for sale in the LS1Tech Marketplace by “Nate Weimer“, and if you are serious about a street-friendly, 9-second car, this G-body might be the answer, packing over 1,000 horsepower on E85 from the LS-based V8.

The Introduction

Big Performance Potential

We don’t know if those horsepower numbers are at the wheels or at the crank, but with the mention of 9-second capabilities, this Oldsmobile is making big power. A 1984 Cutlass Supreme with the V6 weighed in at just 3,200 pounds and while there is some weight removed from the interior of this car, there is no question that the turbocharged LQ4 engine adds some weight. As a result, the car is probably about the same weight as it was when stock, if not a little heavier.

Based on a simple eighth mile-to-quarter mile conversion chart, a car running in the high 5-second range in the eighth, say a 5.85, would be running in the 9.1 range in the quarter mile. A 5.50 in the eighth is in the 8.5 range and getting into the low 5-second range would nearly put the car in the 7-second quarter mile range. That is crazy-quick, but even if it “only” runs in the 9-second range in its current form, it’s not going to lose to many other cars on the street.

So, if you have $20,000 to spend on an automotive toy, you could have a classic Oldsmobile that everyone will talk about after seeing you rip down the local track.

"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.

"Being based on Detroit," says Rall, "I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit's Woodward Avenue with the best muscle car crowd in the world.
