Turbo Systems Tech Center - Tech article from Garrett's website

The Turbo Tech 101 introduces basic concepts as well as general knowledge and understanding of turbochargers systems.

1. How a Turbo System Works
2. Turbocharger Components
3. Other Components
4. Oil & Water Plumbing
5. Which Turbocharger is Right for Me?
6. Journal Bearings vs. Ball Bearings

Turbo Tech 102 is targeted to people who have a general understanding of turbos and how they work. The concepts in Turbo Tech 101 are examined from a more in-depth and intermediate perspective. We assume all information covered in Turbo Tech 101 is fully understood by those reading this 102 course.

1. Wheel trim topic coverage
2. Understanding turbine housing A/R and housing sizing
3. Different types of manifolds (advantages/disadvantages log style vs. equal length)
4. Compression ratio with boost
5. Air/Fuel Ratio tuning: Rich v. Lean, why lean makes more power but is more dangerous

Turbo Tech 103 is aimed at those tech-oriented people who have a very good understanding of turbos and wish to understand the more technical aspects of turbochargers. We assume all information covered in Turbo Tech 101 and 102 is fully understood by those reading this 103 course.
