Some of the greatest feelings in life come with a rise in rpm, a dropped clutch and tests of traction stretching the boundaries of our physiology. These are the emotions many of us cherish, and while many factors can evoke such emotions, the single most influential force behind these kinetic kicks is torque (which is then equated into horsepower).

At The Auto Builder, we’re always on the lookout for products made by real enthusiasts—folks who don’t just sell parts, they live them. That’s why we like the team at DIESELSITE. They don’t just talk the talk—they walk the walk. These guys live and breathe diesel, and they know firsthand the problems truck owners face. They take a hard look at factory OEM designs and make them better. Period.

NASCAR. It’s the most popular televised form of racing, with millions of fans across the nation. In fact, some believe NASCAR’s Cup Series Racing is the most popular sport in America. For all the money expended in Formula 1 (something in the neighborhood of $300 million a year for each of the top teams), it doesn’t approach the excitement, immensity or competitiveness found in this most American of sports.

When building a high-performance vehicle or performing an LS engine swap, your transmission is just as critical as the engine. The 4L65E transmission from Gearstar offers the perfect balance of strength, reliability, and adaptability—custom-built to handle up to 650 horsepower and tailored to your exact specifications.

Building an engine that produces more horsepower than its stock configuration can be done in many ways. However, supercharging has proven to be one of the best ways to make the most horsepower over stock. Superchargers are air pumps that force a “super” charge of air into an engine, which in turn allows the engine to make more power. A Roots supercharger or blower is a sealed case with two rotors inside. It is driven through the crankshaft by belts and pulleys, causing the spinning rotors to force compressed air into an engine.

Undoubtedly, the most significant and influential hot rod component in recent history is the American Racing five-spoke Torq-Thrust wheel. It has been the most-copied wheel ever, as American Racing continues to fight off design infringements. In its many legitimate variations, it has—in many ways—influenced the whole of the aftermarket automotive car culture. No single wheel has ever made such a significant impact on the customizing scene as the Torq-Thrust has.

For diesel enthusiasts and Power Stroke purists alike, performance and reliability are more than features—they’re expectations. For nearly 15 years, the Adrenaline™ High-Volume High-Pressure Oil Pump from DIESELSITE has been meeting and exceeding those expectations, earning a reputation as a trusted upgrade in the 6.0L Power Stroke community.

When you’re pushing the limits of your 7.3L or 6.0L Powerstroke Diesel—whether you’re running big power or hauling heavy—you’re playing a high-stakes game with your transmission. Heat is your enemy, and stock transmission coolers simply weren’t designed for the kind of loads serious truck owners demand. That’s where DIESELSITE steps in with a battle-ready solution: the 40-Row Transmission Cooler.

In the world of high-performance builds, attention to detail sets great cars apart from the rest. That’s why Factory Performance™ Parts, a division of PROFORM® Parts, has taken a fresh approach to a time-tested workhorse with the launch of the new Slant-Edge 100 Amp Alternators—a stylish, high-output evolution of the iconic GM 10SI. Designed for those who care as much about what’s under the hood as how it looks when the hood is up, the Slant-Edge delivers form and function in equal measure.

Whether you’re in the driver’s seat or looking underneath the hood, it’s the first place enthusiasts come to find out what a car is all about. After all, without the right engine package, everything we long for in our cars would be nothing more than static displays of creative artistry.
