Re: Blow Off Valve??

First off, recirculating ones do not cause compressor surge. If they do, then the owner simply hasn't loosened the spring enough. Second the reason many don't like open atmosphere BOVs for our cars is because they release air that has already been measured by the MAS. So adequate fuel is already being sent to the engine via the ECU, but some of the air isn't, because it just got released from the system....so, you run rich after the shifts. Many, but not all, people even experience stalling problems because of this rich condition.

My opinion is to run recirculating, others say they have no problems running open atmosphere. However, that is the reason to go one way or the other...both prevent compressor surge (the entire reason for having either one in the first place)

Your 1996 Mitsubishi 3000GT VR-4 is the 92nd out of the 315 that were made that year. Only 21 of which are exactly identical.
