Dodge Viper SRT-10

| Dodge Viper SRT-10 |The new 2008 Dodge Viper SRT10 boasts more of what performance aficionados crave: kick-in-the-pants, throw-back-in-the-seat power, combined with benchmark braking, world-class ride and handling, a race-inspired interior and bold exterior styling.

While every SRT vehicle offers balanced, overall performance, the heart and soul of the new 2008 Dodge Viper SRT10 is its standout powertrain. For 2008, SRT ups the ante with a new, 8.4-liter aluminum V-10 engine that produces an astounding 600 horsepower and 560 lb.-ft. of torque.



"A legendary big-game hunter once said, 'Bring enough gun!', and with the new 2008 Dodge Viper SRT10, we've created some very powerful artillery for sports-car enthusiasts," said Kipp Owen, Director, Street and Racing Technology (SRT) Engineering, Chrysler Group. "With 600 horsepower, 90 more than before, and 0-to-60 performance in less than four seconds, the 2008 Dodge Viper SRT10 sets a new benchmark for the ultimate American sports car."

The new 2008 Dodge Viper SRT10 will arrive in Dodge showrooms in North America this summer with a new level of customization options, including five new exterior colors, four new interior color combinations and a new wheel design.



Standout Powertrain.
When SRT powertrain engineers set out to get more venom from the 2008 Dodge Viper SRT10's powerplant, their objectives included not only increasing performance, but also complying with stringent regulatory requirements, such as federal Tier 2, Bin 5 and California's Low Emissions Vehicle (LEV) 2 mandates.

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 revised for a 1-millimeter larger bore, 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.



The Viper SRT10's 8.4-liter engine breathes through new cylinder heads equipped 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 combines 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 sends air through a dual electronic throttle control into the intake module.



The air-fuel mixture in the cylinders is ignited by platinum-tip spark plugs fired by new individual plug coils mounted on the cylinder-head covers.

Within the cylinders, pistons are equipped with larger-diameter floating pins with bronze bushings for high-load capability. Forged powder-metal connecting rods are secured with aircraft-quality fasteners for increased fatigue strength.

Engine lubrication is 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.

Spent gases exit through tubular air-gap headers, which not only improve exhaust flow, but also ensure quick catalyst light-off for improved emission control. The headers' stamped stainless-steel outer shell acts as a thermal heat shield for the individual stainless-steel runners that contribute to better flow separation and exhaust tuning.

SRT engineers didn't stop there. Upgrades were developed to handle the 8.4-liter V-10's increased horsepower and torque levels, while improving traction, driveability, and durability.

The 2008 Dodge Viper SRT10's V-10 channels its power through a new, smaller-diameter, twin-disc clutch (a change from the previous larger-diameter, single-disc setup). The new clutch reduces rotating inertia by 18 percent, resulting in reduced clutch-pedal effort and improved engagement feel.



The transmission is the latest evolution of the Tremec T56 six-speed manual, known as the TR6060. It features 10 percent wider gears for higher torque capacity and a new synchronizer package. A new shifter system results in reduced shifter travel. Club racers will applaud a new provision for adding an external transmission cooler.
