Maybe this is a question for it's own thread, but it seems this thread is already there.
Isn't a normal factory located MWE groove in a unaltered compressor housing designed to reduce the surging effects at lower rpms? It's goal is to widen the compressor map on the left hand side (lower airflow side), and it has no benefit on the right hand side? Most MWE grooves I have seen are behind the tips of the compressor wheel.
Therefore a comp housing with no MWE wheel should theoretically flow more air (however at the consequence of surging at lower rpms - not a big deal on a pulling truck).
Reading all the above posts leads me to believe some guys are running a stepped cover or a bushing "to meet the rules" and then adding a 0.25" MWE groove (or as big as rules allow) prior to the comp wheel which would allow more air to reach the compressor (not having to go thru the 2.6" bushing).
Just thinking outloud, but a MWE groove before the tip of the wheel serves a completely different purpose than a factory located unaltered MWE groove which I think is always behind the tip of the wheel.
Thoughts?
