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...

 

DOCTOR, duh


sorry man couldnt help myself

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

 

maybe ur talking about a/r?

 

no where you calculate teh CFM for turbo sizing, there is a DR*VE at teh end,

where do i get the DR for a prelude h22a?

 

Here's a page that explains it:
