Dodge Hellcat Modifications: Pulley Kit, Heat Exchanger & More | dubizzle (2024)

Hellcat is a term used to represent high-performance cars by Dodge. From 2015 onwards, Dodge launched the Hellcat version of the Challenger, Charger and Durango. These muscle cars came with Dodge Hellcat modifications and upgrades providing a powerful performance.

For instance, the 6.2-litre V8 Hemi engine powered the Hellcat versions. Plus, these vehicles are among the fastest cars in the world. Although these Dodge Hellcat versions require no upgrades and modifications, engine and component tuning can further increase the responsiveness of these cars.

Let’s learn more about some common Dodge modifications to turn your muscle car into an absolute beast.

Dodge Hellcat Modifications and Upgrades

Since its introduction, Hellcat has received many motor enthusiast fans from across the globe. Some even modified these powerful muscle cars to achieve even better performance. Do you know Dodge Challenger Hellcat comes with two keys that help maximise or minimise the power and torque? You can find more facts about Dodge which is popular for its high-performance cars.

From suspension tunings to using wider tyres, all contribute to exhilarating performance. However, Dodge Hellcat owners must be aware of the modifications they make when building a project car. For instance, Emirates Authority for Standardisation and Metrology (ESMA) has regulated the modifications to ensure safety and reduce the carbon footprint of cars. Moreover, if you are making Dodge Hellcat upgrades, you need approval from authorities.

You can incur AED 1,000 fine and 12 black points in Dubai if you drive a modified car that hasn’t received approval from authorities. Let’s go through the Dodge Hellcat modifications that will enhance your vehicle’s performance but ensure taking approval for these upgrades.

High-flow Catalytic Converters

A catalytic converter is a device that converts harmful pollutants in the engine’s exhaust gases into less harmful emissions. The standard catalytic converter on the Dodge Hellcat can limit the flow of exhaust gases and reduce the car’s performance. However, high-flow catalytic converters, on the other hand, reduce emissions while allowing for an increased flow of exhaust gases.

Installing high-flow catalytic converters in a Dodge Hellcat can increase horsepower, throttle response and a more aggressive exhaust note. That said, this Dodge Hellcat modification can help improve your muscle car performance by miles.

Pulley Kit Upgrades

Upgrading the pulley kit can help increase the performance of a Dodge Hellcat. The pulley kit drives the car supercharger in the engine, increasing the amount of air that enters the engine and ultimately enhancing the horsepower and torque output.

You can increase the speed at which the supercharger spins, allowing it to produce more boost pressure and deliver more power to the engine. While keeping the power levels optimal, the upper and lower pulley ensures that the supercharger’s bearings and rotors maintain good condition.

This Dodge Hellcat modification can help gearheads achieve a sporty performance from their muscle car. However, the rest of the vehicle must receive proper upgrades to handle the increased power output, such as upgraded fuel injectors, a high-flow car exhaust system, and other supporting modifications.

Supercharger Modifications

If you want to get the most out of your Dodge engine, porting a supercharger snout can prove helpful. This Dodge Hellcat upgrade can increase the amount of air entering the engine. Furthermore, it will help enhance performance.

The supercharger snout in the supercharger connects to the engine’s intake manifold and compresses the air before it enters the engine. Porting the snout involves enlarging and smoothing out the internal passages. That said, it increases the airflow through the supercharger and into the engine.

Heat Exchanger

The Dodge Hellcat is a high-performance car that can cause the engine to generate a significant amount of heat. If the engine gets too hot, it can reduce power and, in extreme cases, cause engine damage. Speaking of that, heat exchangers can help cool down the vehicle.

Dodge Hellcat cars come with Hemi engines that produce more power and generate high heat. That said, Dodge came with its product SRT Power Chillers. If you make Dodge Hellcat upgrades, the SRT Power Chillers help cool the engine and offer sustained performance.

High-flow Fuel Injectors

If you find a Dodge Challenger Hellcat modified or an upgraded Dodge Charger, one thing that may be common is high-flow fuel injectors. These high-flow fuel injectors are a significant modification for Dodge Hellcat owners. These fuel injectors help increase the power and performance of their vehicles.

The engine can receive more fuel to burn during each combustion cycle with high-flow fuel injectors in the Dodge Hellcat upgrade. It can result in more power and engine torque output. Moreover, increased fuel delivery can help prevent fuel starvation and lean conditions. That said, it helps avoid engine damage and reduced performance.

Air Intake Upgrades

Since high-flow fuel injectors allow a rich fuel, air intake upgrades can help maintain a rich air-fuel ratio. Upgrading the air intake can increase the amount of cool, dense air delivered to the engine. It results in increased horsepower and torque.

The upgraded air intake can also help reduce air turbulence and restriction, improving throttle response and overall engine performance.

That’s a wrap to all the Dodge Hellcat modifications you can make in your vehicle and boost your muscle car’s performance. Plus, it is a fact about the Dodge Challenger that the SRT Hellcat is one of the fastest and most powerful muscle cars. The popularity of these cars can be gauged from the fact that Dodge cars in popular movies are a common sight.

If you are a motor enthusiast and buy a Hellcat version from the used Dodge cars in the UAE, you can make the upgrades mentioned above.
