Grudge Racing

Grudge Racing

Grudge racing has dominated the drag racing scene in the southern US States for decades. But in recent years, the Internet has conquered every part of its frenetic life, particularly Facebook postings that have expanded its Southern origins (Georgia, Florida, and the Carolinas) westward to the Mississippi and north to the shores of Lake Michigan. To its masses, its chief dynamic is straight forward: betting. There is no maximum amount—when a dollar changes hands it’s a Grudge race.

Racing Valve Springs

Racing Valve Springs

Here, courtesy of Erson Cams, are several sound rules to remember. The story is developed for those interested in high-performance engine technology and explains the severity of the environment in which the valve spring operates and some of its relationships with a properly functioning valve train. Erson suggests that the primary factors considered when selecting valve springs in a racing engine are, first, the amount of valve lift and, second, engine speeds. As engine speed increases so does inertia, which refers to the valve train’s resistance to changes in speed and direction. To read the full story as printed in Drag Racer magazine click...
Ignition for Beginners

Ignition for Beginners

There are two common types of ignition systems: capacitive and inductive. The coil is supplied power by one or the other. Inductive, which is still the most common and employed on most road-going passenger cars, charges the coil with 14.6 volts and discharges between 200-300 volts into the coil’s secondary windings.

Hemispherical-style combustion chambers have earned a formidable reputation for power generation. The Hemi head broke fresh ground in several areas, including skillfully uniting superior air flow with larger valves. Now, a new company, Hammerhead Performance Engines, headed by Greg Brown, is producing unique Hemi heads for the small-block Ford. With an emphasis on completeness, the innovative head kits include cast aluminum Hemi-style valve covers, Jesel 1.7:1 ratio rockers complete with rocker stand system and all the necessary valve and spring assemblies as well as gaskets.

Competition piston rings and what the OEMs taught us. In our racing world we tend to think of ourselves as the elite corps. But in pistons and more particularly piston ring design, it is not our racing brains that are the driving force but those of the Original Equipment Manufacturers. It would be a glum glimpse of the US racing industry if nothing changed. But it has and nothing could be more illustrative of change than ring development. In fact, if we’re not careful our tow vehicles will operate with 1 x 1 x 2mm ring packs before our race cars. Read the full story compliments of Street Commodores...
