Installing a Borgwarner Efr 9174 Turbo vs a Hellcat Supercharger: a Comprehensive Step-by-step Guide

by

When it comes to enhancing the performance of your vehicle, choosing between a turbocharger and a supercharger can be a daunting task. In this guide, we will focus on two popular options: the BorgWarner EFR 9174 turbo and the Hellcat supercharger. Both have their unique advantages and challenges, and understanding these can help you make an informed decision.

Overview of Turbochargers and Superchargers

Turbochargers and superchargers are both forced induction systems designed to increase the power output of an engine. However, they operate differently and have distinct characteristics.

  • Turbocharger: Utilizes exhaust gases to spin a turbine, which compresses air entering the engine.
  • Supercharger: Driven directly by the engine via a belt, compressing air before it enters the engine.

BorgWarner EFR 9174 Turbo Overview

The BorgWarner EFR 9174 turbo is known for its efficiency and performance. It features a compact design, lightweight materials, and advanced aerodynamics, making it a popular choice among performance enthusiasts.

Key Features

  • Ball bearing design for quicker spool time.
  • Integrated wastegate for precise boost control.
  • Lightweight construction for reduced lag.

Hellcat Supercharger Overview

The Hellcat supercharger is renowned for its ability to produce massive amounts of power. It is a roots-type supercharger that offers immediate boost and throttle response, making it an attractive option for many performance builds.

Key Features

  • High displacement for maximum power output.
  • Immediate throttle response with no lag.
  • Robust construction designed for high-performance applications.

Installation Preparation

Before starting the installation process, ensure you have all the necessary tools and parts. Proper preparation is key to a successful installation.

  • Tools: Socket set, wrenches, torque wrench, pliers, and screwdrivers.
  • Parts: Turbocharger or supercharger kit, intercooler (if required), piping, and gaskets.

Installing the BorgWarner EFR 9174 Turbo

Follow these steps to install the BorgWarner EFR 9174 turbo on your vehicle:

  • Step 1: Disconnect the battery to ensure safety during installation.
  • Step 2: Remove the existing exhaust manifold and turbo (if applicable).
  • Step 3: Install the new turbocharger onto the manifold, ensuring proper alignment.
  • Step 4: Connect the oil feed and return lines to the turbo.
  • Step 5: Install the intercooler and connect the piping.
  • Step 6: Reconnect the battery and start the vehicle to check for leaks.

Installing the Hellcat Supercharger

To install the Hellcat supercharger, follow these steps:

  • Step 1: Disconnect the battery to ensure safety during installation.
  • Step 2: Remove the factory intake manifold.
  • Step 3: Install the supercharger onto the engine block.
  • Step 4: Connect the necessary hoses and wiring harnesses.
  • Step 5: Reinstall the intake manifold if required.
  • Step 6: Reconnect the battery and start the vehicle to check for leaks.

Comparing Performance

After installation, it’s essential to understand the performance differences between the two systems. Both the BorgWarner EFR 9174 turbo and the Hellcat supercharger provide significant power increases, but they do so in different ways.

  • Turbocharger: Generally offers higher peak power but may have lag.
  • Supercharger: Provides instant power with no lag, but may not achieve the same peak power as a turbo.

Conclusion

Choosing between a BorgWarner EFR 9174 turbo and a Hellcat supercharger ultimately depends on your performance goals and driving style. Both systems have their pros and cons, and understanding these will help you make the best decision for your vehicle.
