I'm trying to get an idea of the a/r on the hotside of my greddy turbo. I'm not sure if this is the right section to have this in. Take a crack at it.

 

17Cm is your answer.

Mitsubishi does not use the industries standard (or I should say SAE form of standard) of A/R (which means area / ratio). They use a cm3 area formula. How it corresponds to A/R, I don't feel like figuring it out lol, sorry. Maybe someone else feels like doing the math and making a compario of cm and A/R.

oops......... typo, A/R = Area / Radius Ratio.

It is defined as the inlet cross-sectional area divided by the radius from the turbo centerline to the centroid of that area.

Same for compressor housings, except inlet would be changed to disscharge EXE: It is defined as the DISSCHARGE cross-sectional area divided by the radius from the turbo centerline to the centroid of that area.
