Bov Mod

[JimmyXR6T04]

hey guys,

I'm guessing I've done something wrong here so I've got my guardian angel coming out to have a look at it later this afternoon to see where I went wrong.

Basically I did what everyone else was doing, and I blocked off the part at the back of the cross over and left the BOV to vent atmosphere. I just wanted to see what all the fuss was about, and try some rice for dinner tonight

Anyways, all went well, or so I thought, until I kicked the car over and I noticed that the boost gauge no longer went down to vacuum when at idle. It sat at 0psi. I'm guessing I've either done the mod wrong, or I might have knocked the lines from the boost gauge out. Either way, I'm off to work in a few mins so I don't have the time to pull it all apart again.

I have my mate coming over around 330pm this afternoon to suss it out and call me when he discovers where I made my mistake.

Can anyone with a vac/boost gauge tell me if their car still shows vac when at idle with this mod done? I'm assuming it should.

Cheers,

Jimmy.

it should have vacume at idle at all times.

even with the vac hose off the bov mine still shows vacume.

if u have no vacume the motor will not run or u will have a verry high idle.

Yeah you've just knocked the hose off the bov, they pop off easy as there is no clamp or anything to hold it on.

cheers guys. The car idles fine I'm guessing I've just knocked off the vac line then. My mate will have a squizz and ensure that's the only problem though, but I'm guessing it is.

well, I just took the car for a quick spin, and it idles fine, has vacuum.. everything is fine.. except;

Is it supposed to make that ssshhh sound even when I don't build up boost?? if I put the foot down (1/4 touch) so just cruising, then back off it makes a ssshhh sound.

If I put the foot down and build say, 1-3 psi, it'll make the ssshhh a bit louder, if I go over 5psi it'll make the ssshh tu tu.. then if I really give it stick it'll make the ssshhh tututu..

I sorta like my old gobble gobble noise..

It's louder for sure, but I'm still deciding if it sounds better I'll try and get a vid tomorrow and see if it sounds right.. in the mean time I'll check some of the BOV threads and see if mine sound similar. I don't think it does

[Paradoxx]

Sounds like it's doing the right thing. The turbo is always spinning so even if you 1/4 throttle it you will still get a build up of air in the pipes that gets vented when you go to atmo.

[ROLMDL]

sounds about right mate

I used to drive around with the bov vented to atmo aswell

but now I have a boost/vac gauge so and all the bov and vacumm hoses are

hook up so just wondering what did you do to to make it work with the guages

still working.

look foward to soem vids on the sound.

I dunno what I did when I hooked it up, the vac gauge didn't work.. but my mechanic mate popped over while I was at work and sorted it out. I think I may have just knocked a vac hose off. He's gone away for a while, but when he's back I'll ask him exactly what I did wrong.

It just sounds weird when it makes the whoosh noise after everytime I back off.. I'll get some vids and see what you guys think

that's why I replaced mine with one that's made to vent to atmo. It sh*t me to tears. Now I don't have one at all. Been this way for almost 12 months and I had the front pipe off on Saturday, and the turbo looks brand f***n new still. Not a mark or bend on any blades, and I have been running atleast 10 psi that whole time.

yeah it's a bit annoying. Although, being a manual, surely I'd be placing more stress on everything then the auto would be? it's not that often that you lift the foot on the accelerator in an auto.. or would it be irrelevant??

I'm still trying to get the vids to work

What does it sound like without a bov at all??
