styler Forums Junkie Location: brisbane Registered: October 2004	Re: BOV's Tue, 04 January 2005 07:06 *edit* well at da moment only plumb back is legal and is fitted to some cars at factory. bov's reduce backpressure against the turbo when it is spooled up , backpressure causes it to slow down and bad for the fins. backpressure increases turbo lag, because the turbo has to spool up again. if you are gunning the car and changing gears > pedal down engine powers up turbo turbo spools change gear, pedal up >>>> turbo still spooled engine not using as much turbo flow pressure builds up in front of turbo pressure slows down turbo spinning (backpressure) also atmo and plumb back bovs : orignal bov was a plumb back to elimanate back pressure but it returned the air to the turbo to be compressed again, now when air goes through a turbo it becomes heated and if it returns again it is heated twice wich is not desirable, so atmo bovs were invented so heated air could escape and the air going to the engine would only be heated once. boost, bovs, bleed valves, intercoolers seem simple but can be complicated, id recommend some research. like simple bleed valves cause spiking, there are 2 stage boost controllers etc ask if u wanna know much else and check out other info cheers [Updated on: Wed, 05 January 2005 02:28] [Report message to a moderator]
