Gt3540r With Garrett Ported Shroud Comp Housing .

[discopotato03]

Just in case anyone wanted a port shrouded TO4S .70AR compressor cover for their GT3540R/GT3582R Garrett makes one and it looks like this . The reason I went looking was because a contact and ex employee of Garrett US said that some of the aftermarket ported shrouds do jack shite . I am trying to get the comp map to show the difference .

Cheers A .

Just for my own curiosity, what is the difference physically between a ported shroud and the normal housing???
