i'm sure the information is in the boards somewhere, but i wasn't sure how to go about searching it..


i was wondering what those small holes do on the inlet of this turbo:

it's a massive (by my standards) to4z supporting 750 hp, i was wondering what they do and if they are specific to the larger turbos. i assume that they are some sort of variable vane or something to decrease spool time.


thanks in advance

 

I beleive its the anti surge housing. It help to get rid of compressor surge.
