well i got bord today just looking up retarded crap on the interwebz and started looking at different turbos well was on egay and found this turbo that had some real wierd holes on the compressor inlet was wondering what they were used for and are they suposed to help you

 

looks? I couldn't tell you and I wish i knew

 

Those holes are suppose to sucks air into the compressor housing and make turbo spool faster

 

never heard of that before, interesting....

 

i thought those were like anti surge holes or some bullshit .. or maybe i heard wrong .. whatever

 

Thats what i was gonna say but I couldn't find anything to back it up

 

maby ill call turbonetics tomorrow and try and figgure it out

 

its for surge control
A Ported Shroud compressor is a feature that is incorporated into the compressor housing. It functions to move the surge line further to the left by allowing some airflow to exit the wheel through the port to keep surge from occurring. This provides additional useable range and allows a larger compressor to be used for higher flow requirements without risking running the compressor into a dangerous surge condition. The presence of the ported shroud usually has a minor negative impact on compressor efficiency.

 

^ Bingo.

 

about time theres some useful info being thrown around
