Hello, need to get a new turbo and I have a A/R question....
Lets say that a T3/T04e and a T25 have a A/R of .48-does that mean that they both flow the same? I wouldnt thinks so but need to ask.

I am not saying that these turbos are a A/R of .48, this is just for an example.
Thanks.

this explains A/R. but obviously a smaller t2 turbine is gonna flow less than a t3 turbine with the same A/R

 

Yes the T3 will flow more, A/R can get very difficult. Go look at a GT4088R 1.06 A/R turbine T4 and compare that to a GT4294R 1.01 A/R T4 turbine HUGE DIFFERENCE lol
