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

NEED A NEW TURBO?

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.

What is "Cost Per Horsepower"?

Cost Per Horsepower is a simple way to display and measure the cost-effectiveness of automotive performance upgrades.

In practice, this term is probably more often used to prove someone has wasted money on a specific upgrade or the purchase of an entire vehicle.  For the purpose of this article, we are going to assume the vehicle in question is either a Duramax, Cummins, or Power Stroke diesel truck.

It's what every Duramax lover is talking about right now!

As you’re well aware the L5P Duramax is all diesel enthusiasts are talking about right now.  It’s not unwarranted though as tuning is slowly becoming more an actual thing rather than a hope.  Now that HP Tuners have unlocked the possibilities, Duramaxtuner is wanting to know more.  While getting there hands on the ECM and doing intense R&D.  It would be a good thing to discuss what exactly comes with the L5P.
