Whats the A/R conversion for the 10.5 cm^2 hot side? And what about the cold side? Just curious cause I'm comparing my stock turbo to a friends aftermarket turbo on his eclipse.

 

Read this and you'll probably realize comparing different turbo's A/R is not comparing apples to apples, and therefore not very useful. Looking at the flow maps and other technical specs would give you a more thorough comparison.

Good link, it was helpful.
Ok forget about comparing two different turbos, whats the A/R on the hot and cold side of the stock IX turbo? I figure that the hot side is equal to a .78 A/R (not sure).....what about the cold side?

 

So no one knows? I tryed searching but didn't find anything.
