question , since i dont have a bov and apparently they are not required for a gsr.. Would it not be safer to fit one since all i read is that without it, it can cause turbo / engine dmg.
GSR bov ?

If they aren't required why do they leave the factory with one?

Whoever told you that they aren't required should be shot, brought back as the undead and shot again.

I don't get it...? What does a manifold being made, have to do with needing a bov ??

sorry didnt mean manifold. Meant Pipe between cooler and throttle.. Bad terminology

If you never close your throttle, you won't need a bov.

lol true
10000% wish i got a bov plumbed into my new piping. running 10psi through an E3 engine and anytime i back off the throttle slightly (i.e. not change gears or not rip the clutch straight out) gets massive flutter but then makes the car shake and fks with the revs. change gears or pull the clutch out quickly car is fine. never had the prob on the old piping with bov...

going to get a new pipe with a bov plummed on it so i have my original pipe incase it have problems
With that said, I haven't used one for the last 2+ years, running 24psi and no Blow off Valve. Motor just got pulled out for engine bay to be resprayed and turbo has ZERO shaft play.
I'm not saying to do this, but there's a lot of arguments both sides.

when i weigh the 2 up it only seems that its SMARTER to play the safe game since majority of driving will be done on road not track . Not costing me anything since we have fabricaters who work on the helicopters at work, recons he can make me one with a barter of trade as payment.
Will let you know how it turns out

A lot of turbo specialists seem to think that running no BOV has no ill effects on the turbo at all. Some of those same turbo specialists put their money where their mouths are, and run their own cars that way. One in particular that I know, has ran his like that for 5+years, daily driven on the road. Still the same turbo, and it's still going strong. Couple that with just how durable and tough an MHI turbo normally is, and they will take any abuse running no BOV could give.
That and there is a Mitsubishi that came from the factory with no BOV fitted at all. (IIRC, it was the Starion) This is just one example, there were other cars from other marques that came without a BOV.
Same reason most turbo equipped cars come out of the factory with a resonator box fitted. It makes the car run quieter. That, and primarily the reason I put below...
That's part throttle surge. It occurs with VTA BOV's as well, when run on a MAF equipped car. This MAF is the real principle reason most manufacturers fit BOV to the cars at the factory, as well as noise control. If it was a SD system measured at the inlet manifold, you wouldn't need to recirculate any air at all.
It's certainly not to save the turbo...

Over many many years it will affect your turbo.. Best mate has a daily driven 625hp s15 that runs 40psi of boost with no BOV has no "jolting issues" never had a turbo or misfire issue or anything of the sort!
Touch and go situation really.. a poorly deigned BOV can cause boost spike and boost float and or non accurate hold of boost.
Man it u dont want to run one just dont!!!!!!!!!
You will get a both sides to this story.. Everyone chooses one or the other. at the end of the day just make a decision and run with it.
