GFB dv+ installed

That's what an external wastegate dump and 2J race intake is for, lol

Screamer FTW

Idk about this one but the boomba adapter was annoying ASF! I had to remove it for that reason. It started to sound so ricey and weird almost after my x37. Anyone have a video of this one making sounds? Considering this to fix my boost oscillation problem

 

[TUX15ST]

This barely changes the sounds at all compared to stock, not a big difference by any means, anyone claiming it does is just placebo effect

I agree, I was thinking the same thing but to claim that it sounds some what like a r2d2 bov?? Had to ask

 

[TUX15ST]

Yeah lol, i mean its a slightly different sound, barely noticeable unless your looking for it but certainly not louder

 

[CanadianGuy]

Its not a vent to atmosphere. It vents likes the stock internally but slower. Sound is placebo.

That's why I would not even consider the boomba racing adapter, and would ONLY consider their recirculating BPV/BOV system against this GFB unit.

Jesus christ [MENTION=5976]ron@whoosh[/MENTION] this thing got here fast... thank you sir


Going to install this tomorrow. What should I log before and after for results?

If you can do a WOT pull through 1-2-3, maybe 4th gear speed shifting before/after so we can see if there's a difference in boost between gears, it would be much appreciated.

Boost pressure, speed, throttle position. What you should see with the DV+ is the boost being held between shifts or when the accelerator is released. Stock the boost drops to vacuum almost instantly when accelerator is released.

OK guys I will get r done in the morning

I ended up ordering one from Whoosh. Used coupon code Fist5 for 5% off.

 

[LaserWhisperer]

Just ordered mine, really excited to eliminate the low RPM "bypass valve hang"

 

[TyphoonFiST]

So with this valve....there is no more Bov noise like with my boomba adapter?

This is not a BOV. Therefore yes it will not have the sound of one. This is fully recirc like the stock but stronger as it does not only rely on the spring and has a slower release to help with throttle responce between shifts.

 

[BronxBomber]

I have this installed and you can barely hear anything from the BPV. Super quiet.

 

[DvC]

Just did the stock DV log, waiting for it to cool so i can install and go again

Wonderful post. Log is worth looking over carefully. I had no idea boost dropped from +14 at redline to -10 psi in 0.2 seconds during a shift with throttle lift. Then 0.6 sec to recover to 17 psi back on throttle. Very nice, quick and consistent shifts by the way. Generally dropping less than 2K rpm shift to shift.

If this valve upgrade provides benefits, this is the way to see them. Of course, only fanatics care about 0.1's of a second, but we have met the fanatics and they are us.

Now I wonder what flat foot shifting would show. I only use it on track when trying for a fast lap, but it does seem to hold boost better than throttle lift on shifts.

The next question is Can the boomba Bov adapter work together with this?

See a few pages back the question was asked and I answered. Need longer screws than available is either kit.
