Quote, originally posted by vr6dubnut12 » sorry if this is a stupid question but what are the differences between a bov,diverter valve and wastegate dont they all do pretty much the same thing?
DV and BOV do the same thing -allowing air to be vented out of the system when you lift off throttle. The difference is that a BOV is typically venting that air to atmosphere, and the DV is venting it back in to the intake tract.
a Wastegate does something completely differnt- it controls how much boost the system makes. once the set level is acheived, the excess is vented in to the exhaust tract.
