Nearly 20 years ago, I was fresh out of college and working for Turbo & High-Tech Performance magazine. Back then, so little was known about import performance. There was no information and no resources to turn to as no one had pushed import performance as we would. The racers, enthusiasts and manufacturers that pioneered import performance would have never made such progress had it not been for the chassis dyno. In 1996, Dynojet paid a visit to our magazine headquarters for a demo. After a couple pulls with a project car on a portable two-wheel-drive Dynojet 248, we were instantly…

Project Patience: Supra is Waiting for it’s Time to Shine Waiting for a project to be completed ranks high on the list of enthusiast anxieties. Delays seem almost unavoidable and often add to the frustration and anticipation. For Brent Huckaby, a certified American Petroleum Institute inspector, dealing with these issues seems a little easier since he’s often traveling around the world keeping oil companies in compliance. Patience has proven to be a virtue as this 1997 Supra has taken the long road to big performance. Text and Photos by Richard Fong A Good Match Huckaby’s objective was simple, a…

Is the Percent of Power Gained Going to Be the Same From Dyno to Dyno? NO While some dynos showed comparable gains at specific RPMs, other engine speeds showed much different gains. Since different dynos have varying algorithms on how the load is applied, the boost curve is affected. Hence the most difference in percent of power gains is found in the RPM range that has boost transitioning to its steady-state level. Test Procedure We conducted our dynamometer test utilizing the exact same procedure at each facility in order to ensure consistency and a fair evaluation. All testing was done…

In the modern age of media where CGI and explosions in 3D dominate the silver screen, a younger audience would claw their eyes out during any black- and-white film of the old days. From television, to photography, even to the Nintendo Gameboy, the transition from monochromatic presentations to full color was inevitable. Data logging and display systems in cars and racing recently have followed suit. Decades ago, data acquisition consisted of bulky hardware with low memory and slow capture rates. For many systems, instead of downloading the data to analyze on a computer, engineers printed out near-indecipherable data on long…

Attention to detail is often the difference between winning and losing. Fuel Tech 101 explored the basic components that make up the fuel system: fuel tank, fuel filter(s), fuel lines, fuel rail, fuel pressure regulator and fuel injectors. Fuel Tech 101 also detailed the math behind choosing pumps and injectors that meet the maximum fuel demands of the engine. In Fuel Tech 201, we’ll build upon these basics to explore detailed products, techniques and strategies that compose a high- performance fuel system. Read our Fuel 101 Guide Understanding Ideal Ideal leads to perfection. In order to engineer and design the…

Nearly everyone has gone through or will have to go through the ultimate test of friendship: helping a friend move. The situation worsens if they happen to live in an upstairs apartment and need assistance moving the couch. Although this piece of furniture is mostly symmetrical and balanced in weight, you don’t want to be the unlucky one carrying the lower, heavier end when tilting it up and down stairs. Just as you’d prefer to split the lifting 50/50, your car’s tires ask for a fair and balanced weight distribution. With four tires at your disposal, corner balancing your car…

A blast of performance from a button. A properly designed nitrous-oxide system can reliably deliver a “shot” of additional performance on demand. A simple system with simple controls is able to deliver simple results. If your goal is simply fun, a properly installed, well-engineered kit will deliver. But, what if you want more out of your nitrous oxide system? Sure you can change jets for more power, but what if you need the power delivered in a different way? In addition to the tried and true method of adding “stages” to the nitrous oxide system, new technologies are now available…

Click Here to Read Our 101 Guide to Understanding the Valvetrain Control the flow in, seal the Cylinder during compression and combustion then expel the exhaust and repeat. An engine’s valvetrain is responsible for establishing the exact timing and magnitude of each of the four cycles. The camshaft(s) and the cam lift and timing controls (where employed) conductor the orchestra. While these conductors are usually the focus of performance editorials, we decided to save that topic for another time. Instead, we wanted to focus on the players in the orchestra. These are the basic components that have simply evolved over…

On turbocharged engines, it’s been said, “If you want more power, you need to be willing to sacrifice some boost response.” Today, that’s actually seldom true. While you may be among the two-percent that have the best response turbocharger and turbo manifold for your engine combination, chances are that your current turbo and exhaust manifold do not feature all of the latest performance technologies. Ball-bearing center sections, bleeding-edge compressor and turbine wheel designs and surge-resistant compressor covers are just a few of the newer technologies that are allowing big-power turbos to have improved boost response. While exotic turbine materials, improved…

It’s been said that “You have to start from the bottom, if you want to get to the top.” The same can be said about building a top-performing engine. One needs to start building up the bottom end if they wish to realize top-level performance. Whereas turbochargers, superchargers, camshafts and ported cylinder heads hog the spotlight with big power numbers, the bottom end of the engine is actually responsible for delivering all the power reliably. While rarely given due credit, technological advances in piston, connecting rod, crankshaft and sleeve technology are the main reason why today’s engines deliver more power…

THE FACT THAT NASCAR’S SUCCESS TRUMPS ALL OTHER forms of motorsports in the United States proves that the concept of performance from efficiency still hasn’t fully caught on. Even with its steel tube frame and purpose- built chassis, the behemoth of a NASCAR Sprint Cup car weighs in at over 3,400 lbs. While other racecars and select streetcars utilize carbon-disc brakes or rack and pinion steering, the Sprint Cup vehicles stop with heavy cast-iron disc and caliper braking systems and steer with a clunky recirculating ball mechanism. Yes, these cars go fast, but doesn’t it sound like they could benefit…

What is bulletproofing? In terms of high-performance engines, bulletproofing refers to increasing the power handling capacity of an engine beyond the desired power level. Depending on the design of the engine and the magnitude of the power handling increase desired, the bulletproofing process will vary. The parts and processes needed to build a Honda B20 and a Mitsubishi 4G63 to be bulletproof at 700whp are going to be different despite the fact that both engines are 2.0-liter, four cylinders with DOHC 16 valve cylinder heads. Additionally, the process and parts to bulletproof a Toyota 2JZ to support 800whp is going…

BOOKS HAVE BEEN WRITTEN ILLUSTRATING THE MATH, SCIENCE and design of suspension systems. In the case of coil-over suspension systems, buyers must consider price, application, construction and adjustment capabilities when selecting the best coil-over system for their vehicle. If the objective is to simply achieve a decent ride on a lowered stance, there are a number of options. The quality of the product will determine if it lasts for 10,000 miles or 200,000. If the objective is to tune a vehicle for maximum performance on the street or on the track, a higher investment will be required. Staff Report Price,…

Like the elegantly simple yet intriguingly complex rubik’s cube, setting up automotive suspension is a bit of a mystery that’s difficult to decipher. When analyzing an original 3x3x3 Rubik’s cube, there are a daunting 43,252,003,274,489,856,000 combinations in which you can orient the little squares. Even with over 43 quintillion combinations, there are people who can solve a cube in just seconds. Text and Photos by Sami Sharaf / Illustrations by Paul Laguette So what’s the key to solving intricate problems like Rubik’s cubes and the setup of automotive suspension? First and foremost, taking the time to analyze the system and…

EVERY YEAR, WE TAKE OUR 36-FOOT SPORTFISHER named “No Deadlines” to seek out bluefin and yellowfin tuna. Traveling 120 miles south from Huntington Harbour, California, we end up in Mexican waters more than 70 miles away from land. The last thing we want is a problem with the engines. While marine diesel engines are among the most reliable on the planet, 90-percent of all problems that will arise are fuel system related. Many times a problem in the fuel system can affect both engines, leaving a vessel at the mercy of the seas. To reduce the potential for fuel related…
