I searched for days on this question..

I saw different turbine from 9 blade to 12 blade design, will a 12 blade spool faster?

My idea is more blade = more restriction on turbine inlet so the turbine have to spin faster to flow more and give a better spool, but more blade = more weight...

Any expert can answer this?
 
Its not how many blades you have on your turbine or compressor housing, its how big the inducer/exducer wheels are along with the housings.. More blades or less blades on a certain wheel will not change how much air it can flow..
 
i know but lets say if the a/r and trim are same, but one have more fin than the other... ?
 
Its not gonna matter unless it changes the size of the inducer or exducer which it more than likely wont.. Adding a fin isnt going to do anything..
