How to Lower EGTs and Get That Legendary Turbo Whistle (2013-2018 6.7L Cummins)
If you own a 2013-2018 6.7L Dodge Ram Cummins, you already know the stock Holset VGT has its strengths. It offers quick spooling, responsive low end torque, and integrated exhaust braking.
However, it also comes with a well known flaw: high backpressure and heat.
The factory turbine wheel is designed for strict emissions compliance, resulting in restricted exhaust flow. When you put your truck under load, whether towing a heavy trailer up a grade or running performance tuning, exhaust gas temperatures (EGTs) spike quickly, and drive pressure backs up into the engine.
The good news? You don't need to drop thousands of dollars on a complete turbo replacement or a complex piping kit to fix this. The solution is simple: swap out your stock turbine wheel for the Stainless Diesel 10-Blade Drop-In VGT Turbine Wheel.
What is a 10-Blade Drop-In Turbine Wheel?
The factory VGT turbine wheel uses a higher blade count designed to keep exhaust gas trapped longer to satisfy emission standards. A 10-blade turbine wheel, by contrast, features larger, more aggressively angled blades spaced farther apart.
This open design allows exhaust gases to exit the turbine housing significantly faster, dramatically reducing restrictions in your exhaust system.
Key Benefits of Upgrading to the Stainless Diesel 10-Blade VGT
-
Significantly Lower EGTs: By improving overall exhaust flow, hot gases spend less time trapped inside your turbo and manifold. This directly translates to cooler exhaust gas temperatures, protecting your engine during heavy towing or hard acceleration.
-
Reduced Drive Pressure: High drive-to-boost pressure ratios strain your head gasket and lower engine efficiency. The high-flow 10-blade design lowers exhaust backpressure, allowing your engine to run smoother and more efficiently.
-
Direct Drop-In Fitment: Designed as a direct fit component for the stock 2013-2018 6.7L Cummins HE351VE turbo housing. No custom machining or fabrication is required.
-
That Signature 10-Blade Whistle: Let’s be honest, sound matters. The factory turbine leaves your exhaust sounding muted. Installing this 10-blade wheel restores that iconic, aggressive, high pitched turbine whistle every diesel enthusiast loves.
Who Should Buy This Upgrade?
This turbine wheel upgrade is ideal for:
-
Daily Drivers & Tow Rigs: Drivers who pull heavy trailers and need to keep EGTs in check without sacrificing low end VGT spool speed.
-
Budget Minded Builders: Owners who want maximum performance and thermal control out of their factory turbo setup without spending big money on an aftermarket turbo kit.
-
Sound Enthusiasts: Anyone looking for that distinct, loud turbo whistle without doing a full turbo swap.
