This was a clean 2006STi that came by recently for a quality tune after rebuilding the engine and stepping up to the Dom 3.5XTR from Blouch. This is currently our favorite stock location turbocharger for you Subbie guys looking for consistent 420+WHP results without totally sacrificing response. In comparison to the Dom4XT graph posted a few days ago the spool difference is significant. I find that customers going for more than 450WHP on pump gas will enjoy a rotated set-up much more than running one of the larger stock location turbochargers. So the Dom 3.5XTR is the sweet spot in the line-up and never disappoints. The customer didn't end up doing any head work while going through the motor so that was really the one limiting factor out of the current set-up. I think with a proper set of cams, Kelford 272's or BC S3 cams, we would have seen an extra ~30WHP.

Overall great results out of the new set-up for our friend Matt's 2006STi!

This is the 10CM housing. With the Dominator turbos on the 2.5L AVCS motors we usually opt for the large 10CM hotside to allow for best gains and biggest performance gains in the top end.
