Turbo Question : What Do These Numbers Mean
Ok I see everyone talking about their turbos using three numbers in series like this:
62/65/14
62/74/13ss
Can someone explain these to me?

First number is the inducer side of the compressor wheel in mm.
The second is the exducer side of the exhaust wheel in mm.
The third is the cross sectional area of the exhaust housing in cm squared.
the larger the number, the more air it can flow, but also the slower it will spool.

Here's an interesting little write-up on A/R...

Yeah, why is it we refer to turbos the way we do instead of the way everyone else does?
Who started this means of identifying turbo's. The numbers can be decieving, because you can have two turbos that are 62/65/14 that are completely different because of the Exhaust Inducer and Compressor exducer sizes.
OR is there some standard that will not allow that to happen? OR am I just overlooking something obvious and am proving that public school really does provide an inferior education?

yeah trim would one to know because not all compressor exducers and turbine inducers are the same size. Obviously if they were it would not matter.
As far as giving A/R ratios again if the radius was always the same then knowing the sq.cm. of the exhaust housing would obviously be required (which they give us) However the radius from the center of the turbine to the center of the exhaust housing is not always the same for every turbo? is it?
So basically it is just one of those things to make you go ...hmmmm...why do that do it that way?
