Is it a ball bearing turbo? No

Where is your boost onset and about where would you hit .8 or 1 bar boost? In 3rd gear I made a datalog with the old set-up. 2000rpm up to the point it makes full boost. Then did the same with the new set-up. Seems they both start to make boost around 2200rpm but by 2700 rpm the K27 is 2psi ahead. By 3000rpm the k27 is 4psi ahead. Once rpm gets to 3600rpm the S262 really starts to spool quick and catches up with the k27. On the dyno there is a 70ft lb difference at 3200rpm

What hot housing (T3 or T4) and A/R did you go with? T3 .70

Response is the issue. Once we're at 4000rpm the S262 is a monster pulling all the way to, and probably over 6000rpm if I had pulled it that high. Top end is great but i'm not willing to sacrifice that much low end to get it. They do offer a .55 housing.
