VIPER Truck UPGRADE
2004 DODGE RAM SRT-10 Viper Powered Truck
(from DaimlerChrysler Press
Release) February 2, 2004 - The Dodge Ram
SRT-10 unleashed its Viper power today, taking its place in the
Guinness Book of World Records as the "World's Fastest Production
Only recently off the Saltillo, Mexico, assembly line and not
modified in any way for additional power or enhanced aerodynamics,
the Dodge Ram SRT-10 posted a two-lap, both-directions average speed
of 154.587 mph over a "flying kilometer" on the 4.71-mile oval at
the DaimlerChrysler Proving Grounds here in Chelsea. The record run
by the Dodge Ram SRT-10 was certified by Guinness World Records and
the Sports Car Club of America (SCCA). The previous record was
147.54 mph, set last July by the Ford SVT F-150 Lightning, before
the Dodge Ram SRT-10 went into production.
"When we set out to develop the Dodge Ram SRT-10, our mission was to
create the ultimate performance truck," said Dan Knott, Director,
Street and Racing Technology. "With 500 horsepower, sports car-like
handling, world-class braking and race-inspired design appointments,
we know we reached our goal. Setting the Guinness record today
simply confirms that, and solidifies the Ram SRT-10 as the ultimate
-- and fastest -- performance pickup."
According to Guinness World Records rules, the record speed had to
be the average of two one-kilometer runs in opposite directions
along the same track, made within an hour of one another. The timing
equipment had to be certified as accurate to within 1/1000th of a
second, and supplied and operated by a qualified third party. The
speed of each run was timed by means of sensors at the start and
finish of the measured kilometer, thus giving an average speed over
the full distance.
The Dodge Ram SRT-10 is the third Dodge vehicle branded with the
Street and Racing Technology label, following the Dodge Viper SRT-10
-- the ultimate American sports car -- and the award-winning 230
horsepower Dodge SRT-4, that has taken the sport compact "tuner"
crowd by storm.
Behind the wheel of the Ram SRT-10 in the record-setting run was
Brendan Gaughan, a six-time winner in a Dodge Ram in the 2003 NASCAR
Craftsman Truck Series (NCTS). Gaughan makes his NASCAR Nextel Cup
debut later this month at the Daytona 500 in the No. 77 Kodak Dodge.
"I've certainly driven some fast trucks," Gaughan said, "but I've
certainly never experienced anything like setting a Guinness world
record. I've known for a long time that the Dodge Ram is the
ultimate truck for the race track, and this certainly proves the Ram
SRT-10 is the ultimate performance truck for the street."
Hein Le Roux, research team member at Guinness World Records
traveled from the company's London headquarters to monitor the
"I'm pleased to be here in Chelsea for this record-breaking
attempt," Le Roux said. "Guinness World Records is the ultimate
compilation of superlatives, and I am proud to officially recognize
that Dodge has set a new Guinness World Record."
Le Roux said watching the record-setting speed run was a great way
to begin the new year, in which Guinness World Records celebrates 50
years of world records.
"People aren't too surprised when they hear about expensive super
cars or race cars setting speed records," he added. "But few people
expect a standard production pickup truck, which they can drive
straight off the dealer lot, to be capable of this sort of speed.
That's what makes this such a great Guinness World Record."
With a Guinness World Record now under its belt, the stock Dodge Ram
SRT-10 now heads to Florida, where it will pace the field at the
Feb. 13 Florida Dodge Dealers 250 NCTS race at Daytona International
2004 Dodge Ram
It ain’t bragging if you
can do it. With a maximum speed of 150 mph and the biggest engine in
a performance pickup, the Dodge Ram SRT-10 backs up its claim as the
baddest truck on the block.
The Ram SRT-10 makes the most of its 500 horsepower Viper engine
with a combination of high technology, performance icons and some
“When it came to creating a 150 mph, PVO-designed Dodge Ram pickup,
only the best would do,” said Dan Knott, Director–Performance
Vehicle Operations (PVO). “We took the best parts available, a Viper
V-10, a Dodge Ram 1500 chassis and body, Hurst shift linkage, and a
Dana 60 rear axle. Pirelli tires, Bilstein shocks, a custom designed
power hop damper and the braking system from the Ram Heavy Duty
ensure that we can get the Ram SRT-10 slowed down for the corners.”
More than just a big engine, Ram SRT-10 adds the largest standard
wheels, tires and brakes offered on a production pickup. Unique in a
world of look-alike trucks, the Ram SRT-10 is a radical,
custom-built performance truck, straight from a manufacturer. The
Dodge Ram SRT-10 blends performance cues direct from the Dodge Viper
SRT-10, the ultimate sports car and the baddest pickup on the
market, the Dodge Ram.
The Power and the
From the beginning, the
engineers at PVO knew that this monster truck was a snake. The
8.3-liter Viper V-10 delivers 500 horsepower and 525 lb.-ft. of
Resting on unique engine mounts; the V-10 engine delivers 90 percent
of its whopping 525 lb.-ft. of torque from 1500 to 5600 rpm. The
cast aluminum cylinder block has interference-fit cast-iron liners
and cross-bolted main caps.
The Ram SRT-10 also features a unique oil pan, throttle linkage, new
“Hi-Flow” exhaust manifolds, new transmission mounts and a modified
Ram Heavy Duty radiator tailored to fit the between the NASCAR
inspired grille baffles.
The rest of the V-10 is straight from the Viper, with a six main
bearing crankshaft with cross-bolted main bearing caps. Despite
larger diameter aluminum alloy pistons than the previous
generation’s 8.0-liter Viper engine, the pistons weigh less and are
included along with all-new, lighter and stronger cracked-steel
Cylinder heads on the Viper V-10 are semi-permanent mold (SPM) 356
T6 aluminum alloy. Low-profile die-cast magnesium cylinder head
covers feature steel internal baffles and anti-slosh foam.
The Viper V-10 boasts a single-piece, central dual-plenum, cast
manifold and a single, non-staged two-barrel throttle body for
higher peak horsepower RPM. The intake manifold is an all-inclusive
Integrated Air and Fuel Module (IAFM) with tubular fuel rails,
injectors, sensors, wiring and throttle body. A Ram Heavy Duty
cooling system is modified to handle the needs of the new Viper
engine. A custom dual exhaust system is mounted to new exhaust
The 2004 Dodge Ram SRT-10 focuses its power through a new, purpose
built Hurst shifter and a modified version of the Viper SRT-10’s
Tremec T56 six-speed manual transmission. The T56 is fully
synchronized with electronic reverse lockout. A new 4.5-inch
aluminum driveshaft runs from the Viper-sourced transmission to a
Dana 60 rear axle with a 4.11 ratio to deliver the massive torque to
straight line acceleration, the Ram SRT-10 was also designed to
carve corners and challenge the laws of physics. The engineers at
PVO modified the rack and pinion steering system from a Dodge Ram
Heavy Duty and custom tuned the independent front suspension.
Working with the hydro-formed Dodge Ram 1500 frame, one of the
stiffest in the industry, PVO dropped the Ram SRT-10 one-inch in the
front and 2.5-inches in the rear. New front and rear strut
assemblies and a rear sway bar were added to handle the increased
cornering loads and virtually eliminate body-roll.
“The Dodge Ram SRT-10 delivers simply phenomenal handling,” said
Knott. “But without sacrificing ride quality. This is a truck that
you can run to the store in, and then start tackling apexes on your
favorite set of twisties. And, depending on your right foot, the
V-10 can make the straight-aways really short.”
To make the most of the excellent handling characteristics of the
Dodge Ram 1500, the PVO engineers added Bilstein mono-tube shock
absorbers, a new front knuckle design and shorter and stiffer
performance tuned springs. Next came unique aerodynamic aids to keep
the Ram SRT-10 planted at high speeds and 22-inch custom
“Viper-style” wheels fitted with 305/40 R22 Pirelli Scorpion tires
for extra adhesion. The rear leaf springs were modified and leaf
spring snubbers were added for smoother power launches.
To ensure that the Ram
SRT-10 makes the most of its 525 lb.-ft. of torque, PVO designed a
unique power hop damper to stop axle hop under full acceleration
runs. A Bilstein shock absorber was fitted between the frame and
axle, and now clean launches, even on slicks, are just a right foot
“The power goes down smooth, even as all hell is braking loose under
the hood,” added Knott. “This set-up will wrinkle slicks on an ET
run just as easily as it ruins the competitions day.”
Big brakes, another Dodge Ram staple, are also modified for the 2004
Ram SRT-10. The standard ABS-equipped brakes are fitted with new
15-inch rotors on the front brakes. Rear brakes are modified Ram
Heavy Duty with 14-inch rotors. Front and rear brakes feature unique
red calipers. The new front fascia features NASCAR-inspired brake
cooling ducts to provide plenty of cooling for track sessions.
