Trim = [(exducer^2)/major^2]*100 --> A/R = ???????
Hey guys,
I was reading around and generally turbo's are specified by there turbine/compressor, trim and a/r. I know what trim is...
[(indcuer^2)/major^2]*100 = trim
[(exducer^2)/major^2]*100 = Trim
Basically a ratio of the wheel sizes.
What is this a/r i see noted as well? I would guess air ratio or something to that effect, but what is its significane is i where to purhase a turbo?

aspect ratio. I think it would be like the ratio of the inlet size to that of where the air blows off the blades or something like that.
Generally bigger a/r equals more airflow, but more lag.

Ahh that would make sence. Anyone have a mathmatical definition of A/R? or a further insight?

a/r is area/radius ratio

Explaining it would be alot of typing, a pic is worth a thousand words right
