Garrett T3 specs

[Alfadriver]

Greetings from Denmark. This is my first topic in here. Great site by the way. :D

I was wondering if anyone know the A/R on the turbine and compressor fitted on the 155 Q4?

[Juan AR155Q4]

The turbine is .48, sure. The compressor I think is .50, but no sure on this.
I don´t know the trims, just that it´s T3.

What's the A/R???

Take a look here (http://www.turbobygarrett.com/turbobygarrett/tech_center/turbo_tech102.html), it´s explained better than I could do.

Compressor
A/R = 0,42
Trim = 45
Max Rated Power = 235 hp

Turbine
A/R = 0,48
Max Rated Power = 300 hp

If I remeber it correctly Max Rated Power is given at ~65% efficiency.
