Under full throttle, a dragster
engine consumes 1½ gallons of nitromethane per second;
a fully loaded
747consumes jet fuel at the same rate with 25% less energy being produced.
A stock Dodge Hemi V8 engine cannot produce enough power
to drive the
dragster supercharger.
With 3000 CFM of air being rammed in by the supercharger
on overdrive, the fuel
mixture is compressed into a near-solid form before
ignition. Cylinders run on the verge
of hydraulic lock at full throttle.
At the stoichiometric 1.7:1 air/fuel mixture for nitromethane the flame front
temperature measures 7050 degrees F.
Nitromethane burns yellow. The spectacular
white flame seen above the stacks at night is raw burning hydrogen, dissociated
from atmospheric water vapor by the
searing exhaust gases.
Dual
magnetos supply 44 amps to each spark plug. This is
the output of an arc welder
in each cylinder.
Spark plug electrodes are totally consumed during a
pass. After 1/2 way, the engine is dieseling from compression plus the glow of
exhaust valves at 1400 degrees F.
The engine can only be shut down by cutting
the fuel flow.
If spark momentarily fails early in the run, unburned
nitro builds up in the affected cylinders and then explodes with sufficient force
to blow cylinder heads off the block
in pieces or split the block in half.
In order to exceed 300 mph in 4.5 seconds dragsters must accelerate at an
average of over 4G's. In order to reach 200 mph well before half-track, the launch
acceleration
approaches 8G's. * Dragsters reach over 300 miles per hour before
you have completed reading this sentence.
Top Fuel Engines turn approximately
540 revolutions from
light to light!
Including the burnout the engine
must only survive 900
revolutions under load.
The redline is actually
quite high at 9500 rpm.
The Bottom Line; Assuming all the equipment is
paid off, the crew worked for free, and for once NOTHING BLOWS UP, each run costs
an estimated US $1,000.00 per second.
The current Top Fuel dragster elapsed
time record is 4.441 seconds for the quarter mile (10/05/03, Tony Schumacher).
The top speed record is 333.25 mph (533 km/h) as measured
over the last 66'
of the run (11/09/03 Doug Kalitta).
Putting all of this into perspective:
You are driving the average $140,000 Lingenfelter "twin-turbo" powered
Corvette Z06. Over a mile up the road, a Top Fuel dragster is staged
and ready
to launch down a quarter mile strip as you pass.
You have the advantage
of a flying start. You run the 'Vette hard up through the gears and blast across
the starting line and past the dragster at an honest 200 mph.
The 'tree' goes
green for both of you at that moment.
The dragster launches and starts
after you. You keep your foot down hard, but you hear an incredibly brutal whine
that sears your eardrums and within 3 seconds the dragster
catches and passes
you. He beats you to the finish line, a quarter mile away from where you just
passed him.
Think about it; from a standing start, the dragster had spotted
you 200 mph and not only caught, but nearly blasted you off the road when he passed
you within a mere 1320 foot
long race! course. That, folks, is acceleration.

50 Years
of NHRA Drag Racing.

The
Original "Extreme" Sport in a Nutshell
EDITOR'S NOTE:
When one looks back at 50 years of anything, whether it be lawn bowling, shuffleboard,
or wheelbarrow racing, it's impossible to recount all the memories in just a few
pages. This overview will serve to shed some light on what many feel is the most
intense form of motors port this planet has ever witnessed. NHRA Championship
Drag Racing has always been a festival of speed, color, and characters that is
unparalleled in any other competitive automotive arena. We sincerely hope you
enjoy the images and facts presented here. Happy anniversary, NHRA.
From
an abandoned airport runway in Great Bend, Kansas (circa 1955), to our familiar
megaplexes of the new millennium, NHRA Championship Drag Racing has evolved into
an amazing sport. While other types of promoters strive to "invent"
new and dangerous "extreme" sports, it's no secret that drag racing
is the nation's first and foremost extreme sport. Back in the '50s, there was
only one event (The Nationals), and founder, Wally Parks ran the organization
on a part-time basis. However, the Safety Safari was already spreading the message
about organized, quarter-mile acceleration contests, and while doing it, civic
leaders and law enforcement departments quickly recognized the NHRA's goal to
help eradicate speeding on city streets across America.
The
message of the NHRA Safety Safari was heard loud and clear, because it was their
job to influence the "city fathers" in several different geographical
markets of the organization's long-range goals. Calvin Rice, at the wheel of a
flathead-powered, "slingshot" dragster was the top dog at the first
Nationals. He rocketed through the quarter-mile in a blistering 10.30 seconds
at 143.95 mph.
In 1961, the one-race schedule was doubled,
with the addition of the Winternationals in Pomona, California. The '60s proved
to be the decade of Top Fuel dominance, following a short-lived ban on the use
of nitromethane. Many advancements were made in areas of chassis construction,
rollcages, and bodywork. However, as speeds increased, so did the occurrence of
drivers being bathed in hot oil, as early Chrysler Hemi engines were being run
on the ragged edge. On May 16, 1964 Bobby Vodnick went 7.96 at Bayview Maryland,
and by 1965, AA/Fuel Dragsters were running in the mid-7s at over 200 mph.
At
roughly the same time, a new breed of altered wheelbase, Factory Experimental
Super Stockers hit the scene. In an attempt to increase weight transfer, the front
and rear wheels were moved further forward, lending a "funny" look.
Hence, the name "Funny Car" was born. They, too, went through a rapid
evolution of design, fabrication, and speed. Many of the early Top Fuel pioneers
switched to Funny Cars, and the rest is history. However, from the early Stock
and Super Stockers, up to, and including the Funny Car, we experienced what was
known as "The Factory Wars." Rivalries were intense, as fans packed
the grandstands to cheer for their favorite brand of automobile.
The '70s began with "Big Daddy" Don Garlits
suffering a horrendous transmission/clutch explosion just off the starting line
at Lions Drag Strip in Southern California. Not only did it cut his "Swamp
Rat" dragster in half, it took half of Garlits' right foot with it. That
very incident led the crafty veteran to design a better mousetrap. In 1971, he
debuted a revolutionary rear-engine dragster at the Winternationals, and immediately
dominated the scene, winning in Pomona and Bakersfield within a month of each
other. On November 17, 1972 Mike Snively broke the 6-second barrier, running a
5.97 in Top Fuel at Ontario, California. And the rest is history.
Throughout
the decade, Funny Cars became more noticeable than the quicker and faster Top
Fuel Dragsters. Granted, space for sponsor signage was much more abundant, and
the rivalries between drivers had a tendency to endear fans to the "Floppers."
The "Snake" and the "Mongoose." USA-1 versus "Jungle"
Jim. The Hawaiian against the "Orange Baron," Somehow, those early Funny
car match-ups provided the fans with more sizzle and pop than did Top Fuel, Also,
it seemed as if Funny Cars were everywhere at the time, as match races were abundant
from coast to coast. Dragstrips dotted the American landscape with much more frequency
than they do today It was nothing for a racer to compete in three different states
on any given Friday, Saturday and Sunday To put it in perspective, Leroy Goldstein
drove the Ramchargers Funny Car to a 6,92-second elapsed time in 1970, and in
1975 Don Prudhomme recorded a 5.98. That's technology!
The
'80s saw Pro Stock times range from 7.77 to the 7.20s with household names such
as Bob Glidden, Lee Shepherd, Frank Jaconio, Joe Lepone, and Warren Johnson. Personal
gains in this difficult eliminator came in 1 or 2 horsepower increments on the
dyno, and hundredths of a second on the racetrack. However, all major automotive
brands were still well represented, which added greatly to the fan appeal. The
sport was gaining professionalism in the '80s, as well. Corporate positioning
became the focal point, with national brands lending their support in a much more
open fashion. Names such as Faberge, Pioneer, Budweiser, Old Milwaukee, and Wendy's
became synonymous with our sport. Drivers had to quickly learn how to become "personalities"
and "spokespersons." The era opened up a whole new cadre of necessary
personnel, such as public relations people and marketing specialists, and suddenly,
drivers found themselves traveling with an entourage of hired help.
Performance
didn't suffer, however. The decade saw Top Fuel times plummet from a 5.57 in 1981
to Eddie Hill's histrionic 4.99 in 1988. If speed is your game, Joe Amato debuted
a revolutionary tall, laid-back rear wing, which immediately produced a 260.11mph
blast at the Gatornationals in 1984. That incredible accomplishment was bookended
by Connie Kalitta's 291.54 in 1989. Likewise, the Funny Car contingent was also
turning in stellar performances. Raymond Beadle's 5.868 e.t., recorded in 1981
was improved to the tune of a 5.193 by Don Prudhomme in 1989, and speeds increased
by a bit more than 30 mph, ranging from 250 to over 280 mph. Along with the sport's
prominence and professionalism, payouts increased in the '80s, as well. In 1980,
the NHRA Winston Drag Racing Series Point Fund totaled $236,000, and was split
among the professional categories with $25,000 each for Top Fuel and Funny Car
Champions and $15,000 for the Pro Stock Champ. In 1989, the total increased to
$1,016,600, as Top Fuel and Funny Car C hampions got a check for $150,000 and
the Pro Stock kingpin took home $100,000.
The '90s saw very few "privateers" left in Top Fuel and Funny Car. Sponsor
dollars became increasingly competitive to secure, while the cost of running a
top-notch operation escalated immensely. We were now in the era where fuel crewchiefs
could earn millions themselves. To quote an old song, professional drag racing
became a sport where "only the strong survive." Back in the '70s very
few dragstrips would qualify to be called "Super Tracks." Englishtown,
Gainesville, Ontario, and Indy are a few that always seemed to live up to (and
exceed) the day's performance expectations. However, the National Hot Rod Association
fought long and hard to gain respect within the auto racing community. The '90s
saw more professional facilities, which served to catapult the NHRA from a competition-driven
sport to the lofty status of "family entertainment." Corporate sponsorships
became more 'frequent, as well, such as the "Official Vehicle of the NHRA,"
the "Official battery of the NHRA," or the "Acme Auto Nationals,
present ed by Speedy Spark Plugs."
Perhaps the biggest
news in the sport was ushered in with the new millennium, when NHRA decided to
limit the percentage of nitromethane allowed in its two premier categories--Top
Fuel and Funny Car. While the main focus was safety the necessary by-product came
in the form of less downtime for track clean up. The job of speeding up the show
so fans would see less track cleaning became the crewchief's responsibility Even
though fines (and points deductions) were also handed out, things did improve,
and the fans noticed. NHRA also sought a new qualifying format, whereas time schedules
were tweaked in order to provide the fans with a more constant program of "must
see" on-track action.
All in all, the first 50 years of
NHRA Championship Drag Racing has produced volumes of excitement. During its formative
years, you could make an argument that soundly supports the fact that the NHRA
helped create the entire high-performance aftermarket explosion. Countless crafty
racers began to design better parts that eventually would launch their careers
in manufacturing. Look around. Many of those early racers are some of the most
successful entrepreneurs in America. It seems fitting that the Land of the Free
is also the place where many passionate and inventive hobbyists have turned their
dreams into reality
This was all made possible thanks to the
vision and determination of Wally Parks, founder of the NHRA, which has become
the nation's largest motorsports organization. It was Wally's "need for speed"
that helped create an arena for men to test their ideas, which later became "must
have" products for many a power-hungry high school kid. Today, with NHRA
action reaching millions and millions of households through ESPN2, its momentum
is still building. Many insiders feel this momentum can only serve as a springboard
to the next 50 years.
NHRA RACING
1955:
1 Events
1965: 4 Events
1976: 9 Events
1986:
14 Events
1997: 22 Events
2001: 24 Events
NHRA's founder, Wally Parks, was like many
of us--a true automotive enthusiast who had a passion for success. With a penchant
for racing on Southern California's dry-lake beds, Parks took the idea of safely
staged, quarter-mile acceleration contests and turned it into the largest motorsports
organization in the world.
In the '50s, a young racer from
Seffner, Florida, began to make a name for himself. Don Garlits, later known as
"Big Daddy" quickly became the most feared competitor, as well as the
most respected innovator. It would take volumes to list the many "firsts"
"Big Daddy" is credited with.
The phrase "acceleration
contest" was not generally met with approval in the early '50s, until NHRA's
Safety Safari visited various geographical markets to convince the "City
Fathers" that illegal street racing could be reduced significantly.
In
the early '60s, electronic starts became the new wave. Gone were the days of the
flag starter, and as a result, drag racing became foolproof and much more consistent.
The
fabled "Parker Avenue," named for Chief Parker of the Los Angeles Police
Department, easily became known as the most famous quarter-mile in the nation.
The site of NHRA's second "national" event (the Winternationals) rests
on the grounds of the Los Angeles County Fairplex in Pomona, California, and is
still considered an extremely special strip of asphalt.
Aside
from Top Fuel, many other classes are also credited with their fare share of innovators,
as well. For full-bodied, carbureted cars, such as Super Stock and Pro Stock,
Bill "Grumpy" Jenkins (shown here circa 1970) was always at the forefront
of technology, pushing the limits and forging new ways to develop horsepower (and
still does to this day).
Don "The Snake" Prudhomme
is yet another icon of drag racing as we know it, and one of the handful that
could be considered "household" names in America. After switching from
Top Fuel to Funny Cars in the early '70s, The Snake began a reign of terror with
performances that were unmatched at the time. This photo captures one of those
"shot heard 'round the world" runs, where Prudhomme became the first
Funny Car driver to break the 6-second barrier in 1975.
Over
the years, Gainesville Raceway, located in north central Florida, became one of
the most talked-about venues on the entire NHRA calendar. Its late winter race
date, coupled with premium traction always made for a much-anticipated happening.
In 1984, the innovation brought by Joe Amato and (then) crewchief Tim Richards
proved this facility's legacy, as Amato became the first driver to exceed 260
mph. His innovative, tall, laid-back rear wing was credited as providing greater
down force, due mainly to its lofty location which allowed it to cut through "clean"
air.
While Pomona has its "Parker Avenue," Indy is
considered the Granddaddy of all drag races, as illustrated in this photo from
1968. The year 2001 marks the 47th U.S. Nationals, an event in which winning means
more to a competitor than any other race on the calendar.
What began with a bunch of Chrysler Corporation engineers
running in Stock Eliminator and Super Stock, the Ramchargers became one of the
first successful multicar teams. These now infamous candy-striped cars were well
represented in Top Fuel, Funny Car (with Leroy Goldstein driving here), and Pro
Stock.
Route 66 Raceway in Joliet, Illinois, is but one shining
example of the newest way to expose NHRA Championship Drag Racing to the world.
Its "stadiumstyle" presentation ensures a great view from any seat in
the house. Many of today's megaplex facilities capitalize on multivenue attractions
in order to capitalize on the optimum usage of their seasonal real estate.
Darrell
Gwynn turned heads by joining forces with the New York Yankees and the Steinbrenner
family. Driven by veteran handler Mike Dunn, Gwynnl Steinbrenner Racing is always
poised to defend the "pride of the pinstripes," and recently served
notice by setting the NHRA National Speed Record with an incredible 330.55-mph
charge.
John Force has positioned himself at the top of the
heap in Funny Car by assembling a top-notch group of tuners and a three-car team
to wreak havoc on the competition. Rumors persist of him fielding a Top Fuel Dragster
for 2002, as well.

Dragsters
keep breaking speed barriers
By BOB ARNDORFER
Gainesville Sun staff writer
Kenny Bernstein founded drag racing's 300 Club at the 1992 Gatornationals. Driving
a Top Fuel dragster, he was the first person to break through the 300 mph barrier.
Is a 350
or 400 Club next?
Bernstein's
feat was the motorsport equivalent of Air Force pilot Chuck Yeager flying through
the sound barrier in 1947. They said it couldn't be done.
Today,
drag racing speeds in the 320 mph range are routine, and the 330-mph barrier has
even been broken; all from a standing start on a quarter-mile track, shorter than
the distance between the corner of University and Main and the Seagle Building.
As each
milestone speed barrier is breached in drag racing, the question emerges: Just
how fast can they go?
Is
350 or 400 even possible?
"Back
in the '50s and '60s, they said the laws of physics wouldn't allow you to go 150
miles an hour," said Mike Dunn, another member of the 300 Club who is competing
in the Top Fuel class during this weekend's Gatornationals. "I think shortly
after they made that statement, somebody broke 150."
Back
when the sport was closing in on the magic 300, few people thought it wouldn't
happen, Dunn and others said. As the speed records inched up from 250 to 270 to
290 in the 1980s, the question became not if they could go 300, but who would
do it.
Nine
years after Bernstein broke 300, however, the tone in the pits has changed. Drivers
and crews are suggesting that speeds may have peaked. And that, they say, may
be good for the sport.
"I
think 400 (mph) is technically not impossible," Dunn said. "I don't
think we'll see it happen, though. . . . Whether NHRA or the insurance companies
would let us run 400 is the question. Obviously, safety is the biggest concern,
as it should be."
Three
weeks ago in Phoenix, Dunn hit a speed of 328.22 mph, breaking his official career
best of 321.42 mph. The 328 wasn't official, however, because Dunn wasn't able
in the same event to follow it up with a run within 1 percent of the speed.
The
fastest unofficial speed ever recorded in an event sanctioned by the National
Hot Rod Association was 330.23 mph. It was set in 1999 by Tony Schumacher, who
also is in town competing in the Top Fuel shoot-out. Schumacher's speed is unofficial
because he, too, wasn't able to back it up at the same event.
NHRA's
fastest official speed is 326.91, set by Gary Scelzi in October 1999.
Dunn
said that a decade ago, insurance companies didn't want racers running 300 mph.
Changes in NHRA rules and advances in safety technology, he said, helped convince
insurers that the risk isn't as great as the speeds suggest.
"Today's
cars are safer at 320 than back in 1980 when I was driving Funny Cars at 250,"
Dunn said.
In
an effort to rein in the horsepower, NHRA rules now restrict the size of engines
in the top classes to 500 cubic inches. Restrictions also have been placed on
the size of superchargers -- the device that blows huge doses of air into an engine
-- and the types of ignition systems that can be used.
Another
major rule change affected the fuel mixture for the top classes. Instead of gasoline
or alcohol, Top Fuel and Funny Cars burn nitromethane, a highly volatile fuel.
In the past, NHRA allowed the use of 100 percent nitro in the engines. It delivered
enormous power, but also often resulted in engines exploding during a run.
Today
the 90 percent rule has been adopted, which mandates that nitro can comprise only
90 percent of the fuel mix, with the remainder made up of less volatile methanol.
Dan Olson,
crew chief for Schumacher, has been in drag racing for 36 years. He said he remembers
how difficult it was to get into the "200-miler" club.
"They
thought there was no way you'd ever go faster than 200," he said.
For
most of his three decades in the sport, he thought the sky was the limit. Today,
he said, he thinks the technology and rules may have caused speeds to top out.
"With what we have today to work with, I don't think we'll see much more
than 330 (mph)," Olson said.
Technology
today has caused such increases in power that the biggest challenge now is controlling
it efficiently. With so much power -- Top Fuel cars have 6,000 horsepower, more
than a dozen Corvettes combined -- the trick is keeping the wheels from spinning
on the track. A car without traction doesn't win races.
"In
the past, we could never overcome the track," Olson said. "Now we've
got the power, but the problem is overcoming the track, or keeping the car from
spinning its tires."
Tim
Richards, co-crew chief with Johnny West for Bernstein's team, said he thinks
the new rules will keep speeds in check.
"I
think everybody agrees these cars go fast enough to be entertaining," he
said. "There was a time when the technology was moving a lot faster than
it is today, and there were a lot of big jumps that could be made in speeds.
"Today,
I think what we're striving for is more competitiveness and more consistency,"
said Richards, who started in the sport in the early 1970s when 200 mph was the
brass ring. "That's more important than getting a car to 340."
Anthony
Vestal, a spokesman for NHRA, said the new rules "sort of slowed down speed
a little bit the last year or so." But Dunn's performance in Phoenix, he
said, "shows that these guys are mechanical geniuses and they'll figure ways
within the rules to achieve the speeds."
Speed
is secondary to the main goal in drag racing, Olson said.
"My
goal is to win rounds and win races," he said. "The speeds and (elapsed
times) will come along."
