1986 1,100HP Supercharged Buick: Experience Brutal Shifting with Sequential Gearbox

In this article, we will be diving into the exhilarating world of high-performance cars by exploring a remarkable machine that has been making waves on YouTube. Prepare to be amazed as we take a closer look at a 1,100 horsepower supercharged Buick with a sequential gearbox, known for its brutal shifting and mind-boggling speed. Join us on this thrilling ride as we unveil the impressive features and capabilities of this extraordinary vehicle.

The Journey Begins

The story of this awe-inspiring Buick begins with its humble origins as an ’86 T-Type, not to be mistaken for a Grand National. The journey to greatness started when the original motor blew up, prompting the owner to seize the opportunity for transformation. Little did they know that this would be the catalyst for an extraordinary project that would exceed all expectations.

With the vision of creating a truly monstrous car, a series of modifications and upgrades were set in motion. The installation of a sequential gearbox became a priority, taking the vehicle’s performance to new heights. Coupled with a supercharger and a dry sump, this Buick was destined for greatness.

Power and Performance

When it comes to power, this Buick leaves no room for compromise. With the smallest blower pulley in place, it boasts an impressive 1,176 horsepower. This level of raw power may seem excessive for regular driving, but it perfectly aligns with the demands of high-performance competitions, such as Optima’s events. The Buick is built to dominate the track, leaving competitors in its dust with its sheer acceleration and mind-bending top speed.

However, this Buick is not just a one-trick pony focused solely on power. It is also built to meet the specific requirements of competitive events like Optima. In order to participate, the car must retain its street-legal status, complete with essentials like a radio, air conditioning, and functional car windows. Even with these necessities, the Buick has undergone significant modifications. The motor has been shifted almost 10 inches back from its original V6 position, resulting in a weight bias that is remarkably close to 50-50.

With a weight of approximately 3,800 pounds, this Buick is a heavy contender. Its weight is further accentuated by the inclusion of both the G-body chassis and a full cage, essentially making it two chassis in one. The full cage, meticulously crafted by talented fabricator Sam, ensures both safety and rigidity. This car has big plans for the future, including taking on challenges like Texas 2K and reaching speeds of over 200 miles per hour. It’s a testament to the dedication, skill, and innovation of its creator.

Weight Distribution and Balance

To optimize performance and handling, the Buick’s engine was pushed back nearly 10 inches from its original position, creating a near-perfect weight distribution of approximately 50:50. This adjustment ensures enhanced stability and control, allowing the car to tackle high-speed maneuvers with confidence.

Admittedly, this Buick is no lightweight. Weighing in at around 3,800 pounds, it boasts a solid construction, effectively merging the original G-body chassis with a robust full cage. This combination ensures both safety and structural integrity, setting the stage for extreme endeavors.

Tire Talk

In the pursuit of maximum performance, tire selection is crucial. Experimentation led to the discovery that running 315-sized tires on all four corners provided superior results compared to the original plan of utilizing 335-sized tires. This fine-tuning allowed for better grip and ultimately improved lap times.

In the world of high-performance vehicles, stopping power is just as important as acceleration. To ensure exceptional braking performance, the Buick is equipped with an impressive six-piston brake setup on all wheels. Additionally, a drift breaker system with four additional pistons offers added control during spirited driving.

The Drift Breaker

Although the drift breaker system may not see frequent use, it adds an element of excitement and functionality to the overall package. Designed to assist during drifts and high-speed maneuvers, it ensures stability and control in demanding situations.

While the sequential gearbox may seem counterintuitive, its engagement characteristics are optimized for under-load operation. At higher speeds, shifts become smoother, harnessing the true potential of this remarkable transmission system. At lower RPMs, clutching through the shifts ensures a more controlled and refined driving experience.

Under the Hood: The Rear End

Beneath the menacing exterior lies a full-floating Curry 9-inch rear end. This robust component is designed to handle the immense power produced by the engine. Controlled by a versatile switch panel on the dash, the rear end offers nine different tunes, providing adaptability for various driving conditions.

The nine different tunes available at the push of a button offer unparalleled versatility. Each tune is optimized for a specific scenario, allowing the driver to adapt the vehicle’s characteristics effortlessly. This flexibility provides an exceptional driving experience tailored to individual preferences.


In conclusion, the 1,100 horsepower supercharged Buick with a sequential gearbox is a true automotive marvel. Its journey from a stock ’86 T-Type to an absolute beast of a machine is a testament to the dedication, skill, and innovation of its creator. From the blistering acceleration and mind-bending top speed to the precise gear changes and exceptional braking, this car pushes the boundaries of what’s possible on the road. It’s a testament to the endless pursuit of automotive perfection.
