High Technology Cylinder Head Modifications Improve Engine Efficiency. Click an image to View Full Size
Rolling Thunderz specializes in performance upgrades for Dodge Viper Cylinder heads with sophisticated cylinder head modification services that are scientifically advanced.

Rolling Thunderz extensive experience in understanding the many different Viper street car and race car heads provides us with the unique ability to offer custom cylinder head modification services that are specifically designed for each type of cylinder head from the first generation Viper RT/10 heads to the new Viper SRT heads.

The Phase 2 Cylinder head system offers additional porting modifications for improved airflow with stainless steel 2.02 intake and 1.60 exhaust valves, stronger valve springs and light weight titanium retainers that enhance efficiency and improve the acceleration rate of the engine.

This cylinder head upgrade offers a reliable and efficient increase in V10 engine power and a very desirable improvement in performance and acceleration.

Performance increases of 50 plus horsepower have been reported with the use of our Viper Phase 2 cylinder heads, when good intake and exhaust system upgrades are already installed.

Shaft mounted rocker arms with 1.7 ratios recommended for optimum performance.

Generation 1 / 1992 - 1996 Heads
Generation 2 / 1997 - 2002 Heads
Generation 3 / 2003 - 2005 Heads
High technology headers improve engine efficiency and increase power. Click an image to View Full Size
Viper Headers
The production exhaust manifolds on a Viper are considered to be a performance restriction, particularly for a large displacement V10 engine that requires more exhaust flow capability.

The installation of exhaust tube headers can provide a significant increase in exhaust air flow and improve engine efficiency. The key ingredient for superior performance in a Viper Header is the shape of the collector, where five exhaust tubes merge into the collector pipe. A race header style 5 into 1 merge collector, with a gradual transition, significantly improves exhaust flow by allowing the exhaust gas to maintain velocity. Sustaining a high exhaust velocity is the key to allowing the exhaust system to create efficiency and thereby produce more power.

Since the Viper engine has 5 cylinders that discharge exhaust from each side of the engine, there is even greater potential to benefit from more advanced header technologically, such as the super-tuned long tube Tri-Y headers produced by Belanger. The benefits of the Tri-Y headers are that it provides a better transition of exhaust flow from the primary header tubes to the dual exhaust system, by directing the exhaust flow into 3 merge collectors, known as the Tri-Y. The gradual and efficient exhaust flow provided by the 3 merge collectors of the Tri-Y header maintains high exhaust velocity and produces superior performance for the V10 Viper engine.

The Belanger Tri-Y headers have proven to deliver 50+ horsepower gains with the installation of a complete Belanger Viper exhaust system.

The Belanger Viper headers are technologically advanced and proven to deliver great performance. The super-tuned long tube, Tri-Y headers are mandrel bent with 1 3/4 inch primary tubes and 3 inch collectors. High temperature ceramic metallic coated inside and out and nickel chrome finished.

These headers are also OBD2 Compliant, which means that the headers are also designed to function properly with the Viper‘s computer so that the check-engine light does not activate after the headers are installed.

Viper High Performance Exhaust
The production exhaust system for a Viper is also considered to be restrictive for a large displacement V10 engine. The installation of a high-flow exhaust system with larger diameter exhaust pipes and low restriction mufflers will improve the Viper engine’s breathing capabilities and significantly increase power and performance. High flow Catalytic converters also help to flow more exhaust and produce more power.

Generation 3 / 2003-2005 SRT 10

This shaft mounted rocker arm assembly provides additional valve lift and
more efficient valve motion to produce more power.

Viper Shaft Mounted Rocker Arm Systems
This competition shaft mounted rocker arm assembly is specifically designed for the V10 Viper engine with high ratio rocker arms that provide more valve lift and more efficient valve motion. The 1.7 ratio shaft mounted rocker arms open the valves higher than production 1.6 ratio Viper rocker arms to improve engine breathing. The increased intake valve lift helps to flow more air into the Viper engine and the increased exhaust valve lift helps to flow more exhaust out from the V10 engine.

The shaft mounted rocker arms also promote better and more efficient valve motion by creating more precise valve-train geometry. The needle bearing equipped rockers also help to reduce friction and provide improved efficiency.

The increased valve lift and more efficient valve-train motion produces more power and improves V10 Viper engine performance.

The T&D Competition Rocker Arms are the product of years of testing and refinement. T&D rockers are designed with Computer Aided Design and CNC manufactured to ensure precision for each application.

Competition Shaft Mounted Rockers are available for the 2nd and 3rd Generation Dodge Vipers. The 3rd Generation Viper SRT-10 rockers are different from the original assembly for the RT/10 and GTS. Rolling Thunderz worked with T&D machine products to develop the new shaft mounted rockers arms for the Dodge Viper SRT-10.

High Flow air filtration and induction system components
improve air flow efficiency and increase power.

Induction system airflow improvements will help to increase power and improve performance. Air filter systems that use low restriction high flow air filter elements provide more air flow. The K&N high performance air filters # 33-2085 (2 required) improves air flow to produce more power.

Plastic, rubber or polymer materials retain less heat and flow a greater volume of cool air. The K&N Fuel Injection Performance Kit # 57-1508 for 1995 to 1998 Viper RT/10 & GTS models is reported to produce 13 hp at 5300 rpm.

Smooth bore inlet tubes increase air flow with less turbulence to provide more horsepower. The Mopar (P5007362) black smooth bore hoses fit all RT/10 & GTS models.

Air intake systems with better aerodynamic shape promote more flow and increase power. The Vararam VR-1V Viper Air Induction system is a multiple venturi design that is more than 100% efficient and capable of flowing over 2000 cfm.

This air intake system seals to the inlet side of the hood scoop to provide a ram air system that is reported to increase manifold air pressure by 3/4 of pound which can produce 15-17 horsepower at 70 mph. Vararam guarantees a performance improvement of either 3 tenths of a second or a gain of 3 mph in a ¼ mile drag test when compared to the stock production Viper air intake system.

The 180° thermostat helps engine to run cooler and produce more power by reducing
air intake temperature. Fits all 1992-2002 Viper engines.

Viper High Performance Thermostat
The use of a thermostat with a 180 degree opening rate helps to reduce engine operating temperatures. This reduction of engine operating temperature helps to flow cooler air into the motor and since cooler air is denser, more oxygen is available for the combustion process. Reducing air intake temperature by 10 degrees can produce a 1% increase in engine power.
