Frequently Asked Questions
How much power does a turbo add?
A turbo typically adds 30-50% more power depending on boost pressure, intercooling, and engine tuning.
What is pressure ratio?
Pressure ratio is the total absolute pressure (atmospheric plus boost) divided by atmospheric pressure. A ratio of 1.8:1 means 80% more air density.
