Speed Density Systems Performance Reliability For Modern Engines
Modern engine technology is changing our concept of how we increase engine torque and fuel economy.
Why Oil Filters Matter To Extended Oil Change Intervals
Neglected oil change intervals can ruin the best engine oils and filters. As engine oil and the filter accumulate miles, they become contaminated with carbon, water and various acids, all of which are a byproduct of internal combustion that will form a film of black, gooey sludge on the interior parts of the engine.
Fueling Choices: Factors For Carburetion Or A Bolt-On TBI Fuel Injection System
If you’re building a performance engine, should you fuel it with a carburetor or some type of electronic fuel injection (EFI) system? If the application is a late-model vehicle that came factory-equipped with EFI, that decision has already been made for you.
Intermittent Engine Misfire Analysis
Even for an experienced diagnostic technician, attempting to diagnose an intermittent misfire condition that occurs only under specific driving conditions can be a frustrating exercise. Let’s begin by getting the basics out of the way. As we know, the general causes of a misfire fall under the general headings of 1.) ignition, 2.) fuel density, 3.) compression and 4.) timing failures.
Volkswagen’s 1.4L Engine Reinforces Turbocharged, Direct Injection Technology

Tracking Down the Coyote: Capturing Ford RestoMod Engine Work
One thing that is becoming popular is known as a “restomod.” This is the art of combining the old with the new. Even though newer body styles are not sought after to restore, the technology is what’s important. When restoring a nostalgic car, things like fuel injection, bigger brakes, independent front suspension, air conditioning and air ride tend to be hot topics. Engines of today outperform their predecessors along with five- and six-speed automatic and manual transmissions. So why not mix the two and have the style of yesterday with the technology of today?

Building Top Super Comp Engines
What does it take to build a winning engine for Super Comp drag racing? The Super Comp drag racing class runs on a 8.90 time limit, with essentially no rules regarding engine displacement, carburetion or type of vehicle. Engines can burn either gasoline or alcoho, but no nitro or nitrous. Engines can be naturally aspirated
