You can throw all the upgrades you want at any given car, but their effectiveness is limited by the rubber that holds the car to the ground. In the world of automotive performance and motorsports, tires are a sacred component. We wear through them quickly, we always want more, and there are way too many options in the market to keep track of. However, tires are becoming more advanced in different specialties of use such as off-road, daily driving in winter or summer, or various forms of motorsport. In road racing and street performance, Toyo holds a massive presence with its…

Some of the most famous and life-changing inventions were stumbled upon by accident. One such discovery, Evapo-Rust® Super Safe Rust Remover, is to the hands-on enthusiast as a Post-It Note is to the office worker. Like Post-It Notes, Penicillin, Super Glue and microwave ovens, Evapo-Rust was a discovery of happenstance, a byproduct of research for a different purpose. In 1997, chemist David Harris labored with various chemical solutions in the quest for a rust inhibitor. While testing different formulas on pieces of steel left in the corner of a room, he noticed that one actually removed rust. However, it required…

The Fundamentals of Automotive Performance Whether you’re just starting out or you’ve already modified your car, understanding the fundamentals of bolt-on performance is the first step to making power, increasing performance and getting the most from your setup. In this issue, we’ll cover everything from air intake systems to full-fledged turbocharger kits. AIR INTAKE SYSTEMS Air intakes are one of the easiest ways to increase the amount of air going into your engine. With a properly selected intake, your engine wlll benefit from cooler intake air temperatures for additional performance. EXHAUST SYSTEMS Removing restrictions for outgoing exhaust gasses is one…

There’s a reason why enthusiasts choose aftermarket air intakes as one of the first performance modifications. Not only are most intake systems fairly straightforward to understand and easy to install, they typically yield substantial power gains as well. With that said, don’t let air intakes’ apparent simplicity fool you. Aftermarket intakes require extensive knowledge and engineering to design and build. By Sami Sharaf Stock OEM Parts Traditionally, original equipment manufacturers (OEM) address three essential categories in the design of a vehicle’s air intake system. First, a factory intake system must lend itself to extended service intervals. As such, filters need to…

ECU tuning is the tie that binds an engine’s performance together. Gone are the days of jetting and synchronizing carburetors, replaced instead with modern handheld tuning devices and laptops. With numerous options available ranging from a simple reflash blackbox up to infinitely adjustable fuel and ignition mapping software, tuning solutions cover the gamut of modifications from bolt-ons to dedicated racing builds. By Stanley Yee Safety First When vehicle manufacturers program ECUs, the margin of safety is large which results in conservative mapping of ignition and fuel tables. While this can leave untapped performance potential, it gives a safety cushion to…

Your average internal combustion engine may sound smooth and composed from the outside, yet the internals work constantly to generate a series of explosions that set metal components into motion at a high rate of speed. Sure, an engine must be tough in order to produce hundreds or even thousands of horsepower. Yet the smallest inconsistency in timed motions, materials or fluids can reveal that engines are more delicate than you might think. By Cameron Parsons Fuel the Fire Before digging into the fuel system, it is best to gain a basic understanding of fuel itself. Although plenty of manufacturers…

When it comes to increasing your vehicle’s power output, forced-induction systems are the pinnacle of bolt-on performance. Out of all the bolt-on modifications available for today’s popular vehicles, forced-induction kits can offer the greatest gains in horsepower and torque. High-quality turbocharger or supercharger kits can bump power output by 40- to 50-percent. When paired with an upgraded engine foundation, forced-induction kits can double, triple or even quadruple the power production of an engine. The bottom line is forced-induction systems offer the best solution for maximum power increases. By Sami Sharaf Decision Time If you’ve decided that a forced-induction system is…

Heat is a killer. It boils fluids, starts fires, melts and warps important components. There’s no sign of frictionless engines arriving any time soon, so until then, we’re stuck with the byproduct of friction that is heat. Given that cars are filled with moving parts, electrical currents and combusting materials, it would appear that cars excel in making noise and generating dangerously high temperatures. Performance vehicles move parts even quicker, from engine internals, to transmission gears, to differentials, only making components hotter. Cooling temperatures throughout the drivetrain will not only keep a car running longer, but will potentially help it…

Racecar drivers that double as engineers will almost always excel in competition. However, the backseat-driver-equivalent of engineers that claim to be racecar drivers are the worst. These types that love to chase setup adjustments down to the molecular level, they treasure logged data and long debates about spring rates, chassis flex and roll centers. While most of their hypothetical ramblings aren’t wrong, the level of detail in their arguments frequently prove irrelevant in real world situations. One of the most important lessons anyone can learn in tuning their suspension is to fully understand how the different components work together and…

Making more horsepower and going fast is both fun and rewarding; however, there’s really no point to any of it if you cannot stop quickly and safely. While most factory braking systems prove adequate for the daily commute, going to the track or even spirited driving through the canyons could quickly expose the shortcomings of stock equipment. Fortunately, brake components can be upgraded to rein in the speed, helping you to slow down to go faster. By Richard Fong Factory brake systems often feature a compromised blend of components optimized to provide adequate cold braking performance, longevity and reduced brake…

Like eye-catching shoes, wheels make an automotive fashion statement with practical application when properly selected. Wheels are arguably the first thing that people notice about a car. They can be practical, sporty, casual or formal. The reality is wheels make more than a fashion statement, they can influence the acceleration, braking and handling of a vehicle. By Richard Fong Less is More Vehicle dynamics can be helped or hampered depending on the wheel selection. Wheels contribute to unsprung weight, which is any part of a vehicle not suspended by the springs. In addition, they contribute to rotational inertia, which must…

It’s surprising how little is understood about tires. Just look at the number of cars with tires worn down to the belts lining up at your local tire shop when the first rain of the season begins to arrive. What’s worse is that some people think tires are just chunks of rubber used to cushion their vehicle’s ride. They couldn’t be more wrong. As the only components that make contact with the ground, tires serve an important role, delivering mechanical grip, comfort and safety. By Richard Fong The Right Class of Tires Tires provide mechanical grip (traction) for your car.…
