Grudge Racing: The Speed, Money, and Drama Behind the Sport

Speed, Adrenaline and Pure Theatrics

Grudge racing has dominated the drag racing scene in the Southern 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 River and north to the shores of Lake Michigan.

To its mass of fans, its chief dynamic is straightforward: betting. There is no maximum amount; when a dollar changes hands it’s a grudge race.

The money won and lost, sometimes in sizable amounts, is only surpassed by the pride or the poor judgment of the car owners, entrants, drivers and spectators—such adventure, such potential for gain, such drama. Still, in the rapid passing of an 1/8-mile, the prospects of returning home $10,000 poorer are agonizing.

This small-block Ford is energized by HPE Hemi heads. It has already distinguished itself by defeating turbo rivals, a rare occurrence in the nitrous-oxide-dominated grudge game.

A Strictly Cash Economy

In their pre-race negotiations, a grudge racer attempts to learn as much as possible about his rival’s racing history and the competitiveness of the rival’s car. They operate with “stips,” an abbreviation of “stipulations” that specify what is allowed: small-block-powered car on 28/10.5 tires with a cast intake manifold and a single 4bl or dual 4bl carburetors. If your opponent has a history of swapping engines, the stips might have a clause that allows you to view the engine before the race.

When all is settled, perhaps a week in advance of the race, the deposits of the two opponents are sent to a third party, a neutral person known as the “DP” man (an abbreviation of “deposit” man). The deposit acts as a contract between two people who have agreed to race. At the track, before the race, the full wager is handed over to the DP, who is entrusted with the monies and the responsibility of enforcing the stips, and then dispensing the money to the winner.

Grudge-race cars are mostly nitrous-oxide-assisted; they also compete in shoot-out events. These are organized by a promoter who guarantees to pay a sum of money to the racers if sufficient cars are entered into the event. A typical arrangement might pay the first four places: $3,000 to the winner, $1,000 to the runner-up, and $500 each to third- and fourth-place finishers.

Alternatively, they draw chips, like poker chips, that specify a number and a letter, “L” or “R,” which signifies the “left” or “right” lane. The two racers that draw number one are paired for the first round and similarly with number two and three and so forth.

Though grudge racing has no formal tech inspection, the racer’s routine checks include fuel and nitrous levels, and spark plugs, which are usually replaced after each round of racing. Before discarding the plugs, racers perform a color check on each, and adjustments are made to the ignition or nitrous oxide systems, if necessary.
To achieve optimum contact patch, the 10.5-inch drag radial rear slick is fitted to a 12-inch-wide rim. In diameter, the tire measures approximately 28 inches. The front tire on Jonathan May’s machine is a 150/60 ZR17, from a motorcycle rear.

These pairings introduce further potential for monetary gain, which might vary from $500 to $2,500. During the drivers’ meeting, racers will ask the promoter if he has any objection to their placing grudge-race bets with their first-round opponents. Usually, there are no objections.

Both grudge racing and shoot-outs operate as No-Time events, the objective is to shroud in mystery as much race-car detail as possible. Obviously, should a potentially lucrative match arise, it’s in each racer’s interest that many of their performance details remain unknown.

Atlanta race car preparation specialist Scott Milner says, “You’d be forgiven for thinking grudge racing attracts questionable individuals, but often it’s the opposite. Their racing world is more organized than you’d expect.” More importantly, their word is their bond. “If you don’t pay your bet,” he explains, “you’re finished. Word gets around, and no one will race you. A stain on your name means your grudge-racing days are over. Most people do what they say they’ll do.”

Scott Milner owns and operates Coupe Performance in Covington, Georgia, near Atlanta. The company constructs 15 to 20 complete race cars each year and services a further 60 to 70 for competition each racing season.

Drama and Comedians

For some, though, the most annoying aspect of grudge racing is the theatrics of the spectators, particularly those crowded around the rear of the cars preparing to leave the line. Chaotic scenes to some, perhaps, but for those engaging in the histrionics it is the most enjoyable aspect.

Accomplished grudge racer Jonathan May says, “It can be organized chaos, but there’s nothing personal in their sometimes hostile negotiations. It’s just business—as they call it. I see it as comical.” For most of us, trash-talking is a curious endeavor, and grudge racing, for good or ill, has its share of outlandish comedians.

As in most racing categories, the grudge game has fostered a diversity of machinery, frequently in resplendent condition. There may be some that give the appearance of a backyard special in a deceptive effort to help betting chances. But heroic failures don’t exist because there is always a car that can be matched with yours.

Greg Brown of HPE introduced his Hemi cylinder heads for small-block Fords at the PRI show in December 2016. A year later, at the same event, his Hemi for the LS debuted. What’s it been like in the intervening months? Brown tells us, “It’s been like living at Cape Canaveral at launch time!”
Generating optimum power from Hemi heads with nitrous oxide can be elusive, but HPE’s small-block Ford Hemi design succeeds with a combustion chamber of a different formula: Its innovation merges the best of the Hemi with the wedge.

Winning Formula

The race car most often lured to the starting line, at least in Georgia, is the Fox-body Mustang. Produced from 1979 to 1993, the abundance of these vehicles and their conversion to race cars has spurred an industry endowed with dyno cells, chassis-tuning departments and spray-painting booths that remain busy throughout the year.

Supremacy, unsurprisingly, is the objective, but trumpeting your success can be detrimental to your racing prospects. Nonetheless, internet bench racers can adeptly calculate an 80% win ratio when they see it.

A visit to Coupe Performance facilities in Covington, Georgia—one of the most successful preparation shops in the country—reveals around 50 race cars, all with their hoods shut to the visitor’s prying eye. Founded by Milner in 2001, he acknowledges the Fox-body has an OEM rear suspension that resembles a competition 4-link system. Therefore, it’s eminently suited to competition. The car is also relatively light with a plentiful supply of racing components available.
