When it comes to turbochargers for diesel trucks, Stealth Turbos have made a name for themselves by offering performance, reliability, and quality upgrades across the board. Whether you’re driving a 6.6L Duramax, 6.7L Powerstroke or a 6.7L Cummins, Stealth turbos can provide solutions for a multitude of different needs and wants—from stock replacements to high-performance setups. In this blog post, we’ll break down the key differences between Stealth’s STR, Mach 1, and Mach 2 line's of turbochargers and help you decide which one is the best fit for your driving needs.
Over the years, GM has changed a lot regarding the turbos they use on Duramax engines. Not only have they changed manufacturers a handful of times but each RPO has its own unique measurements for key components. This can make it a headache when trying to track down exactly what the measurements of your stock turbo are. Luckily we've compiled this list of stock Duramax turbo specifications along with other helpful information so you can get a good idea of what you're already working with before you dive into the sea of turbo upgrades these trucks have to choose from. However, while some turbos may have the same peak power output, the size and shape of specific components can affect things such as exhaust gas temperature, drive pressure, and turbo efficiency range.
Turbocharging diesel engines is nothing new. The most basic premise of a diesel engine is the more fuel and air you mix during compression, the more power you get.
Types of turbocharger systems:- Wastegate Turbocharger
- Fixed Vane Turbocharger
- VVT/VGT Turbocharger
- Compound Turbocharger
- Twin Turbocharger
- Dual Scroll Turbocharger
Between 1885 and 1916 a few patent applications were submitted for products that address the general concept of turbocharging, but it was in 1925 that Swiss Engineer Alfred Buchi put the first commercially available turbo on a 10 cylinder diesel engine. Turbochargers use exhaust gas pressure to drive a Turbine Wheel that is connected to a Compressor Wheel. The compressor wheel forces cold air into your engine. You're using exhaust pressure to create boost pressure.
