How the heck do you read a turbine map?
I know compressor maps, they're easy to understand (there's plenty out there on how to read them), but I have no clue what each turbine map means.
Anyone have any resources?

I'm pretty sure that you read the inner circle. That's where the turbo is most efficient, in that range. Ussually it's some were near 74%, that range tells you were the turbo is efficient. After you leave the inner circle your turbo losses efficiency (power), which often happens with smaller turbo's. For example on a t25 though you're boosting 18 psi you're making less power than you were at 14 psi, because the turbo is not really efficient passed 15 psi.

I'm talking about a turbine map.
That link seems to help a little bit, with the exducer bore information, but doesn't say anything about the turbine map.
