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 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.
