The little I read about BOV's is exactly what he said. The charged air needs somewhere to escape, hence the BOV. I also heard that by blocking this you could potentially damage your turbo in the long run, due to pressure spikes being fed back into the turbo when you snap the throttle shut. this video should clear it up a bit for you, at least the first 5 mins of the video!

I learnt about it in grade 1. dude if you want to remove or block the bov, then just do it ffs. I cant remember reading a thread entitled 'my turbo blew up because I have no blow off valve'mods could you close any threads that ask the stoopid bov/ no bov question from now on? :argue: Link to comment Share on other sites More sharing options...

It only caused my cooler piping to blow off instead. Invest in a turbosmart kompact. Link to comment Share on other sites More sharing options...

The car was running no BOV. Just something to think about. Link to comment Share on other sites More sharing options...

The car was running no BOV. Just something to think about.My FG had a rooted turbo with 10,000kms on the clock. No mods, no nothing. Just stock as a rock & had just been to my efficient ford dealer for a service where they found... nothing.XFT discovered the problem in their pre mod inspection & advised me to take it in for warranty before they touched anything but I decided to get it upgraded instead, hence quite a bit more rwkw than I would've got.The biggest issue to worry about with the turbo IMO is the oil feed line which has a filter that blocks up with particles & can have the turbo running dry. A simple check every now & then by putting your hand on the feed line when the engine has just been started to see if it's warming up is a good precautionry measure.
