Has anyone tried to open the inlet on the turbo it seems constricted but perhaps that is on purpose to start the air compression. I thought that this would best be done after the intake side though and that porting the inlet and output would help flow.
thoughts? Thanks

 

I think most people when they want to improve the flow on thier turbo just opt to get a larger one. also I think that the inlet and outlet of the compressor size have to stay the size they are ....
