M35 Bov?

[m35stagea]

so i did the coke can mod tonight and seemed to get rid of the farting issue... How bad is it not having the blowoff functioning? Should i look into the grub screw mod?

There is mechanism why it may not be good..

But its pseudoscience at best no one really knows and there are many people on either side of the fence... Personally i have never run them in any of my drift cars. 20+ psi. Had no dramas.

[Sticker Dude]

yeah well we purposely never ran one on the CTS Drift Car as we found it held the boost better that and the fact it was one less part we had to worry about failing. But i was just worried on a stock car such as these it might have some issues. i guess ill wait n see...haha

[m35stagea]

I have blocked mine off...

Got vl bro?

So fellow Stag owners, in regards to the coke can mod....what is the overall feedback and recommendation...to do or not to do..

How have people found it on stock motors with stock turbos???

[Ross]

I did it over a weekend, the noise became so annoying after the first day I removed it reverted back to stock.

[pbk1776]

Is it worth to install aftermarket one?

[scotty nm35]

Not really, the stock one can be just as good if you seal the small bleed hole (grub screw mod) but the car may not be as docile when you back off from boost.

Docile... that was not problem when I did that mod.

I found it good when on of off the throttle but when cruising on the Highway at 115kmh it tended to stutter and was very uncomfortable. Had to stop on the trip to remove the grub screw. Fortunatley it only takes 5 minutes to remove.

[ECR33_RB25DET]

Did the coke can mod. Very straight forward.

Great results; eliminated the farting, seems to be slightly more responsive, got the fully sick VL flutter sound which is manageable. Certainly turns heads when people look that it is a wagon.

As Andy mentioned, wait till you take it on the highway. Drives like a dog.

I'm not exactly sure what the fix is... but once I changed the intake and tuned it with the E-Manage I no longer get the farting... Have been driving it around for about a year with no issues.

Thanks for the heads up. So far had it cruising at 90kmh at constant speed, seemed quite ok, will see how it goes over 100kmh.

yeah mine was mostly fine too when i blocked the hole in the BOV. sometimes on the highway it was a bit rough, but i got over it ..........

[spoolin12]

Take it on a long hill and when you try and maintain a steady speed. When you ever so slightly back off the car will begin the shudder.

It drove me nuts. That and the stupid sound. Would be fine if it was a 1000kw beast... but its a wagon... with alot less power.

Took it for a drive today across Melbourne (Moorabbin to Geelong and back). Kept it steady at intervals of 90kmh, 100kmh, 115kmh and 120kmh. If you are steady on the throttle, not like a taxi drive on/off, I could not fault it.

Have to agree. I ran mine with the grub screw for many 10's or thousands of kms on highway, never an issue.

My car has the super hectik vl fluttaz, but I can't work out why. I just assumed it was an a/m bov, and never got round to looking at it.....until my turbo blew.

I've pulled the BOV off and checked all the lines to make sure someone hadn't blocked them for teh fluttaz. Do the BOV's fail very often?

[ECR33_RB25DET]

now just wondering whether to keep it or put on a new stock BOV as I do not want to kill the turbo.....

[PN-Mad]

HKS in their wisdom decided not to give the kit I have a BOV. So my Dose brings all the Lebs to the Yard, and they're like, mines lower than yours....

My std BOV did similar, [fully hectic sound included] annoyed the crap out of me and made the car surge on light throttle transitions I took it off to check it out. Ended up having a ruptured diaphragm, I replaced it with std BOV off another VQ25det and the problem was solved, driving the car was so much better.

I replaced mine with a Turbosmart Dual Port. Theo has the same one, and Scotty has a Turbosmart Kompact. Little bit of flutter but if you're smooth it's hardly noticable.

I didn't like the idea of replacing one BOV having issues with a second hand one when they're all prone to doing this.
