Google sucks if I type in ar vs cm I get a million racing videos and chemisty formulas dealing with argon and measurements of gases...

Ok ar is area radius yadda yadda

ar picture click me

Cm is usually 6 or 7 or 18 or whatever bigger the number larger the housing size.

I've never seen a real comparison and all my knowledge on the subject is in ar ratios

What is the relationship between the two?

Lets say you have a .48 T3 garrett is that comparible to a 6cm. But how far is it off.

Then lets say you see a 30cm on a big ass dumptruck in a coal mine is that 30cm equal to a 1.36 or 1.5 or 1.7 /ubbthreads/images/graemlins/dunno.gif

All of this is good to know.

I've owned a 14b then went straight to a garrett in a t3 .48 and a T3 .63 and a bullseye .55..... the .63 Garrett pulled harder than any up top. Then I stepped to a s362 schwitzer/borg warner but the turbine wheel dwarfed the garrett and of course with a .80 compressor in a grown ass man size turbo was no comparison to any of the Garrett's I owned. I've now sold the schwitzer and have bought the new. There's not alot of info on these things so hope someone that knows understands the question I'm asking.

I can't go any further in detail the new turbos is the top secret. /ubbthreads/images/graemlins/devil.gif I do know the compressor in a small housing has made 650 to the tires on a dsm so hoping for a little more out of this behemoth.
