That's the same as our experience on a Dynapack chassis dyno and a conservative engine dyno at MODE (Bob Holcombe, Motorsport Design).
Best repeatable numbers on a 3.4L Euro 930 with a K27-7006 was 455hp on MODE's dyno. Raise the boost and the same numbers hit at a lower rpm, not more gains up top.
To the wheels on the Dynapack, similar 930s with K27-7200s top off around 375hp.

Responsive with stock cams or mild cams like SC. Lots of fun on the street.
