i just got confused i know on turbines the bigger the better for flow to a certain point but it's the opposite for compressors right ????correct me please thnx

 

A turbo is a compressor and a turbine mated together. The larger the A/R the more air it can flow in general.

 

There is a problem with your question.... it's VERY broad. And if someone replies with an answer like neal did, someone else may not understand what it ACTUALLY means.

I refer you to the stickies... cause this is a very INDEPTH discussion

 

thnx guys for replying but i did read the stickies,,,, ok i 'll refrase my?... let's say you're buying a turbo so you look for a bigger a/r turbine side for reduced back pressure and better flow but do you look for a bigger a/r on the compressor too or it's the opposite ' i'm thinking that a smaller a/r comressor will not allow any air to escape around the vanes' notice i don't mean the trim thnx guys
