Could a Hellcat Engine Work for an Old Car?

The Hellcat engine is a powerful 6.2-liter supercharged V8 engine that produces 707 horsepower and 650 lb-ft of torque. It is currently used in the Dodge Challenger Hellcat and Charger Hellcat models. However, could it also be used in an old car?

Engine Size and Fitment

The Hellcat engine is a large and powerful engine, so it would not be a simple task to fit it into an old car. The engine bay of most old cars is much smaller than the engine bay of a modern car, so there would be limited space for the Hellcat engine. Additionally, the Hellcat engine is very heavy, so it would need to be supported by a strong frame and suspension.

Driveline Modifications

In addition to the engine, the Hellcat engine would also require a number of driveline modifications to work in an old car. The transmission, driveshaft, and rear axle would all need to be upgraded to handle the increased power and torque of the Hellcat engine. These modifications could be expensive and time-consuming.

Cooling and Fuel System

The Hellcat engine produces a lot of heat, so it would need to be equipped with a high-performance cooling system. This would include a larger radiator, intercooler, and water pump. Additionally, the Hellcat engine requires high-octane fuel, so an old car would need to be equipped with a fuel system that can handle this type of fuel.

Brakes and Suspension

The Hellcat engine would also require a number of upgrades to the brakes and suspension of an old car. The brakes would need to be upgraded to handle the increased stopping power of the Hellcat engine. Additionally, the suspension would need to be upgraded to handle the increased weight and power of the Hellcat engine.

Electrical System

The Hellcat engine would also require a number of upgrades to the electrical system of an old car. This would include a high-output alternator, battery, and wiring harness. These upgrades would ensure that the Hellcat engine has enough power to run properly.

Conclusion

It is possible to fit a Hellcat engine into an old car, but it would be a complex and expensive project. The engine would need to be modified to fit into the car, and the driveline, cooling system, fuel system, brakes, suspension, and electrical system would all need to be upgraded. If you are considering this project, it is important to do your research and make sure that you have the resources and expertise to complete it successfully.
