Default what does DR stand for
Im looking at finding the right size turbo but no-one wants to help me. What is the D.R (density ratio) stand for? how can i find it for the H22a prelude?

Im trying to find a suitable turbo sizing and its hard reading teh compressser maps when i dont know all the parts of the formula...

The only DR i've seen here is to refer to drag radials.
