BD Diesel Howler VGT Turbo Kit for 03-07 Dodge Cummins

The BD Diesel Howler VGT Turbo Kit is a top-tier upgrade for your 2003-2007 Dodge Ram 5.9L Cummins. Designed for enthusiasts seeking better spool, increased torque, and improved top-end power, this turbo kit uses advanced Variable Geometry Turbo (VGT) technology to adapt boost to your driving conditions.

How the Howler VGT Works

Unlike standard fixed-geometry turbos, a VGT turbo has adjustable vanes in the turbine housing. These vanes change angle based on engine RPM and load, delivering:

• Faster spool at low RPM: More torque and quicker response.
• Improved top-end power: Sustained boost for high RPM performance.
• Better efficiency: Reduced stress on engine and turbo, longer lifespan.

How the BD Diesel Howler VGT Turbo Works: A Technical Look

The Variable Geometry Turbo (VGT) in the BD Diesel Howler kit is what sets it apart from traditional fixed-geometry turbos. Unlike standard turbos, which have a single turbine housing and fixed vanes, a VGT turbo has adjustable vanes inside the turbine housing. These vanes can change their angle depending on engine speed and load, which gives your Cummins several key advantages:

1. Faster Spool at Low RPM:
   At low engine speeds, the vanes close slightly, narrowing the exhaust path. This increases exhaust gas velocity and spins the turbo faster, giving your engine quick boost and more torque without lag.

2. Improved Top-End Power:
   At higher RPMs, the vanes open up to allow more exhaust flow. This prevents restriction and maximizes airflow for higher horsepower and sustained performance, perfect for towing or performance driving.

3. Better Efficiency & Longevity:
   Because the turbo adapts to your driving conditions, it reduces stress on the engine and turbo components, extending their life and maintaining consistent boost pressure.

4. Why It Beats Traditional Fixed Turbos:
   Fixed-geometry turbos are optimized for a specific RPM range. Outside that range, performance drops. The Howler VGT turbo continuously adapts, giving your 5.9L Dodge Cummins smooth, responsive power across the entire RPM band.

Installation Tips & Kit Options:
For enthusiasts installing the BD Diesel Howler VGT Turbo on a 03–07 Cummins, the install kit includes all necessary hardware for a proper setup. This ensures the turbo is mounted securely, the exhaust and intake components are aligned, and your engine is ready to handle the improved airflow and boost.
