How VVT/VGT Turbochargers Work on Your Diesel

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. 

Compressor and Turbine of HE351VE Cut Away with Vanes
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.

You've been BOOST-TESTING your diesel WRONG!

[fa icon="calendar'] May 29, 2021 3:34:00 PM / by Paul Wilson posted in Boost Leak, Boost, Boost Test, Stealth Boost Tester

[fa icon="comment"] 0 Comments

Boost Testing your diesel is essential!  Common symptoms of a boost leak include Increased Smoke, Higher EGTs, Excessive Lag, and Loss of Power.  Every truck that comes in our shop here at Calibrated Power, gets a boost test.   It seems about 85% of them have a boost leak when they show up.  Most of the time customers report still seeing peak boost on their gauges despite a boost leak. 

If you work with diesel trucks long enough, you’ll see leaks just about everywhere in the charged air system at one time or another. Remember, the charged air system includes anywhere from the turbocharger to the intake manifold. Your Intercooler system, Exhaust Gas Recirculation components, and even the Turbocharger compressor cover can all develop boost leaks.

High EGTs? Bad MPGs? Excessive Smoke?

[fa icon="calendar'] Mar 28, 2021 11:30:00 AM / by Paul Wilson posted in Boost Leak, Boost, Boost Test, Stealth Boost Tester

Does your diesel have High EGTs, Excessive SMOKE, Increased Turbo Lag, and Less Power than it used to? Let’s talk about boost leaks.

Your truck needs air! Not a little bit of air. Your diesel engine needs all the incoming air it can get. Increasing air in the combustion process will help manager your Exhaust Gas Temperatures, Limit your smoke output, and increase your power.

This is why boost leaks kill diesel engines. Boost leaks can result in a smokey, laggy, dog-of-a-truck, which runs hot and burns fuel. Basically, the exact opposite of what you want from your diesel.

Boost leaks commonly occur in boots and clamps throughout the charged air system. That’s anywhere from the turbocharger to the combustion cylinder. Your intercooler system, Exhaust Gas Recirculation components, and even the turbocharger compressor cover can all develop boost leaks over time.

How to: Perform GM VATS Relearn

[fa icon="calendar'] Nov 15, 2019 7:00:00 PM / by Paul Wilson posted in how to, VATS, Knowledge Base

[fa icon="comment"] 0 Comments

There are a few circumstances when you will need to relearn your Vehicle Anti-Theft System (VATS) relearn.  This process is also known as resetting your Passlock or Passkey VATS system.  While the Passlock and Passkey systems are slightly different than VATS the trouble shooting them is fairly similar.  We suggest doing your research or have your truck professionally diagnosed prior to you begin this process.  

 

Possible trouble codes

  • B2947: SHORT TO GROUND ON THE PASSLOCK SENSOR POWER CIRCUIT
  • B2948: SECURITY SENSOR SIGNAL CIRCUIT VOLTAGE HIGH
  • B2957: SECURITY SENSOR SIGNAL CIRCUIT VOLTAGE LOW
  • B2958: BCM SIGNAL INPUT VOLTAGE HIGH
  • B2960: BCM READING A VALID BUT DIFFERENT CODE VALUE THAN PREVIOUSLY LEARNED
  • B3031: BCM IS IN LEARN MODE BUT DOES NOT SEE A VALID PASSLOCK™ SENSOR CODE
  • B3033: PASSLOCK™ TAMPER
  • P1626: LOSS OF THE STATE OF HEALTH
  • P1630: THEFT DETERRENT PASSWORD LEARN MODE
  • P1631: INCORRECT PASSWORD FROM THE VTD SYSTEM
  • P1632: UNDECIDED PASSWORD SENT FROM BCM

COST PER HORSEPOWER

[fa icon="comment"] 0 Comments


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.
