2008 - 2010 Dodge Viper cars: up to 600 horsepower

2013 Dodge Viper

Land vehicle Vehicle Car Sports car Automotive design

For 2008, the Dodge Viper SRT used an 8.4-liter aluminum V-10 engine that produces a full 600 horsepower and 560 lb.-ft. of torque. 0-60 times were reported at being under four seconds, 0-100-0 in under 12 seconds, and braking 60-0 comes in less than 100 feet.

For "extended 2009" models there were four new exterior colors: GTS Blue Clear Coat, Snakeskin Green Pearl Coat, Viper Race Yellow Clear Coat, VOI X Edition Silver Clear Coat. New features included Premium Tan Interior Package, Nappa leather seats with perforated centers, black and tan two-tone trim, and a tan canvas convertible top (roadster only). The 2009 Dodge Viper also got a modified steel frame, fuel tank, and filler tube, new optional wheels, and a revised center console bezel with recessed window stitches.

oh20 reported that the 2008 Viper Coupe and Convertible both averaged over 200 mph around the Transportation Research Center's 7.5 mile oval test track in Ohio. The convertible even averaged 197 mph with the top down. Coupe and convertible have similar drag (aerodynamic) numbers, according to representatives of the SRT team.

The invoice price on the 2009 Viper SRT10 Coupe was $82,989 for the base car, which had an MSRP of $89,340; Customer Preferred Package 21B added $12,060 (MSRP $13,550). The gas guzzler tax added $1,751 to the cost but Chrysler charged owners a rounded-down $1,700. The destination charge of $930 was the same for the dealer and the buyer.

SRT powertrain engineers had to increase performance while complying with new regulatory requirements. Working with specialists from McLaren Performance Technologies and Ricardo, Inc., SRT engineers began by following the racer's basic formula for more power: bigger displacement, more efficient breathing and higher engine speed.

The new Dodge Viper SRT10's deep-skirted V-10 aluminum engine block was bored out 1 mm, raising the displacement to 8.4 liters from 8.3 liters. With strengthened bulkheads and improved water jackets for better cooling, the block includes pressed-in iron cylinder liners and cross-bolted main bearing caps for strength and durability.

Horsepower didn't come only from the engine, the use of a plastic hood allowed engineers to increase the airflow through the hood scoop; openings along each side are not just for show, but to circulate air within the engine compartment, to keep power going with a warm engine. It also lowered weight and helped keep the Viper costs down. Other body panels are also plastic, and carbon fiber is used for some structural parts to keep weight down.

The Viper SRT10's 8.4-liter engine had heads with Computer Numerically Controlled (CNC)-shaped combustion chambers, larger valves and Variable Valve Timing (VVT). VVT electronically adjusts when the exhaust valves are open and closed according to engine speed and load, allowing the engine to "breathe" cleaner and more efficiently.

The 2008 Dodge Viper SRT10 V-10's two-piece intake manifold combined a cast aluminum lower with smooth runners for better air flow, bolted to a die-cast aluminum upper plenum. A revised air-cleaner box with a low-restriction filter sent air through a dual electronic throttle control into the intake module.

Platinum-tip spark plugs were fired by individual plug coils mounted on the cylinder-head covers. The pistons themselves had larger-diameter floating pins with bronze bushings for higher loads. Forged powder-metal connecting rods were secured with aircraft-quality fasteners for increased fatigue strength.

Engine lubrication was managed by a larger oil pump and a swinging oil pickup adapted from Viper competition engines, to improve oil pressure in high-rpm and hard-cornering conditions.

Tubular air-gap headers improved exhaust flow and ensured quick catalyst light-off. The headers' stamped stainless-steel outer shell acted as a thermal heat shield for the individual stainless-steel runners.

The 2008 Dodge Viper SRT10 used a new, smaller-diameter, twin-disc clutch (a change from the larger-diameter, single-disc setup). The new clutch reduced rotating inertia by 18%, resulting in reduced clutch-pedal effort and improved engagement feel.

The TR6060 transmission was the latest evolution of the Tremec T56 six-speed manual. It features 10% wider gears for higher torque capacity, and a new synchronizer package. A new shifter system had less shifter travel. There was also now a provision for adding an external transmission cooler.

14-inch brake rotors were gripped by Brembo 44/40 dual opposing piston calipers in the front and by Brembo 42/38 dual opposing calipers in the rear. Anti-lock braking (ABS) prevented lockup during hard braking.

The suspension had lightweight, high-performance aluminum control arms and knuckles, damped by lightweight coil-over shock absorbers. SRT engineers retained the tried-and-true Dana M44-4 rear axle and outfitted it with a new GKN Visco-Lok speed-sensing limited-slip differential for improved traction.

The Dodge Viper SRT10 used polished, forged aluminum, 18 x 10-inch front and 19 x 13-inch rear wheels available in three styles: the five-spoke, the H-spoke and the all-new Razor wheel with five U-shaped spokes. The wheels are clad in Michelin® Pilot® Sport PS2 tires. The four-groove tread-design tires provide maximum grip, reduced road noise and superior handling in both wet and dry conditions.

2008 Dodge Viper styling and bodies

Buyers could choose the bezel finishes on the center instrument panel and console. The body was available in Roadster and Coupe forms, both using a new hood with a larger, more efficient hood scoop for air induction and larger, functional hood louvers to cool the 600-horsepower V-10 engine underneath.

Eight exterior colors were used, including Venom Red, Snakeskin Green, Viper Violet, Viper Orange and Bright Blue. Racing stripes continued to be an option with six dual painted stripe colors: white, black, silver, graphite, blue and red.

The only body panels shared by the two Vipers were front fascia and fenders, hood and doors.

The Dodge Viper SRT10 Coupe's hard top with its "double bubble" styling was more torsionally stiff than the Roadster; it had increased downforce and high-speed stability with its sloping roofline and deck-lid spoiler, as well as an additional 6.25 cubic feet of trunk space than the Viper SRT10 Roadster, for a total of 14.65 cubic feet. The roof and headliner structure had more room to accommodate a safety cage, while maintaining as much headroom as possible.

The Dodge Viper was made for a while longer, though no 2010 Viper was in the press book. Four new exterior colors were used: GTS Blue Clear Coat, Snakeskin Green Pearl Coat, Viper Race Yellow Clear Coat, VOI X Edition Silver Clear Coat.
