So I was doing some searching on youtube and came across this American douche's video about his BOV

Anyway check it out. I'd be pretty pissed if my BOV was working the way his does with his extra efficient twin turbo setup. BOV FAIL anyone???

Some of the comments are pretty good and he gets pretty defensive

It does seem odd, but reading the comments the makers of the product genuinely believe the product works and the theory behind it... I'm curious as it is difficult to see past the apparent flaw in the design.

what's up is they broke their blow off valve in the design stage and decided to make it anyway. They do make filters for BOV's (Blits Super Sound had them for a while) but I think they were only there to change the sound it produced. This thing is blowing air out at idle and at wot and he says it's because of how efficient the turbo setup is. BS! This thing would play havoc on an Airflow metered setup, you'd be coughing and spluttering all over the place if you even made it out of the drive.

EDIT - Here's the link to the BOV on the manufacturers website clicky just go to products then BOV. Apart from them sounding not too sure what their BOV is exactly, it also says it will never leak boost. I guess that means aside from at idle or at WOT with an extremely efficient turbo setup :D:(;)

there is nothing wrong with what he is saying

the company had some brilliant ground breaking idea of having a BOV that opens at low load/under vaccum, from memory it was for quicker throttle response, as when you crack the throttle, the air has a much shorter inlet path to the plenum, because intercoolers and piping and the whole turbo system is a big restriction.

the guy in the video is talking about that product specifically, because it draws in air under vaccum, people like to put filters on them. but hes saying that because the bimmer turbo is so 'efficient' and flows enough air, that there is actualy no vaccum through the BOV (again, keep in mind, this is product specific).

stupid thing is, if there is no vaccum though the BOV, there is no need to use their product on that car lol. that said it will probly open if you suddenly stab the throttle. i still found it funny though

Edited by VB-
Maybe I'm just being a troll... but... "FAKE AND GAY."

yeah they see you trolling.... They Hating... lol

But seriously it is legit. Check out their website I posted the link to it earlier. seems they have figured out a way to make all the jap BOV's obsolete due to their new "better" design

    • I am probably calling this too early but I think I found what part of my problem is. I have a couple of dents that are fairly close to each other and I tried to fix them individually. Recently I put one larger coat across all the dents and sanded it and for the first time ever it's all even except for the edge where the bare metal is, I just need to put some putty there. I'm ordering some better longer blocks that are more flexible. Other good news is that the other repairs on my panel are flat even with the guidecoat. It's these 2 dents which are an absolute c*nt l lol.
    • Murray will have better input, but I'd be going with less filler, and aimed at the low spots mainly, and hence won't need as much sanding, which then means get the guide coat on earlier. That's how I'd do it, BUT, I'm not a pro, I'm a DIY hack who will then get the shits halfway through, and have one spot awesomely repaired, and the other spots look like a 3 year old was left unsupervised with workshop tools...
    • Where is the most common place to locate it? Disappointing that Garrett won’t make a fitting for it since they know everyone will use it
    • A HICAS fault really should not cause the engine to go into limp mode. These cars are so old that the systems barely talk to one another. The thump might be the lockoff solenoid valve for the HICAS (the safety valve) getting closed, to lock the rear wheels "straight". I say "straight", because when my HICAS used to shit itself before I took off and nuked it from orbit, it would lock up with the rear wheels wildy non-straight and you'd need 45° of steering wheel to drive straight. Take off and nuke it from orbit. First step is to pull the smaller of the two plugs out of the HICAS CU. See if it stops misbehaving. You can also (whilst leaving it plugged in) try to get the HICAS CU into diagnostic mode by doing the pedal dance, or by connecting a CONSULT capable diagnostic reader into the car and seeing what it has to say for itself. Can't do either of these with it unplugged though. 1st gen HICAS is a ballache. I would do a complete delete. I did do a complete delete.
