The DV+ is also good to ensure a long diverter valve life. I can't tell the diff on my stage 2+ but I like knowing that my dv is much stronger.
I've had dv+ spacer and then the golf r one as well the 2 peice diverter valve. Now I have the forge blow off and I love it! It sounds louder and also hear it more often. I really havent felt any power differences so really just a personal preference.
The rev D valve can suffer from massive leaks even brand new as the plastic piston cannot be fitted tightly enough to seal while still being actuated properly by the solenoid. The Rev G seals perfectly but eventually the diaphragm will rip, especially if you are running extra boost or a KO4. The DV+ is extremely strong and can handle 50psi or so. Also, you only have to oil the piston on installation, it requires no maintenance or additional oiling. You will only notice a performance improvement if your stock diverter is failing or has failed. That being said, they sound great, last a long time and can handle more boost than either revision of the OEM valve. Not the first mod I would do to my car, but I just got a moderate tune (+51hp and 80lb/ft) and the DV+ works very nicely with the added boost.
I installed yesterday on my audi s3 and has that vibration not sure if it's something wrong, it's kinda annoying but I dont mind it if it's that dnt affect anything. And I forgot to put some oil on it as well 🙃
I had my OEM IS20 and an IS38 blow while using the Turbosmart 50/50 BOV. I’m not saying the turbos blew due to having that BOV, but I since have gone back to the stock DV, and haven’t had an issue since.
hey bro may i know which dv is better? gfb dv+ or 034 dv?
I was actually debating this myself like getting a whole bov/dv setup but it’s not really necessary you’re on uni stage 2 right? From my understanding we aren’t running passed 25 lbs of boost we won’t need it
Website claims they can handle 30 psi of boost
yay! first mod i did to my used a3 2.0 tsi but don't expect that woosh sound because this doesn't vent to atmosphere. spools a bit quicker and no surge back to the turbo. had it for the past three years no issues.
Hey man.Did you lubricate it as the video suggests?
LMAO bruh.... Im dyin right now!!! Funniest random sentence @ 1:57
I don’t think that’s how the placebo effect works 😂
For me the gfb dv+ is very helpful if you’re stage 2 or up .. cause the stock dv is designed to handle only 26-27 psi maximum, so sometimes stock dv drops boost over 23-24 psi and like me I used a jb4 piggyback tune it was always drop boost in only 22-23 psi’s settings after I installed the dv+ it’s really make different in handling boost, 25 psi without any problems, and so smooth throttle and fast boost chagring and always peak boost is in point .. that’s my experience
If it's only holding 22-23 psi, your DV is defective then. I have no problem holding 25+ PSI on the stock DV.
The stock dv was engineered to handle way more boost than the average tuner could afford to put through it.
My MK7 does the same thing with the JB4. I can't figure out how to fix it
U all own golfs lol losers
@@nickramsay2216 And what brought you in a video dedicated to golf guys?
I bet you wish u had one, LOL LOSER
Okay… i just got my DV+ from oscaro ans find out your vid !
1)What about the gain from the turbo lag ? Does it last ?
Your vid confused me a little bit.
2) Does it hurt the turbo to keep it on ?
I got a 7R 300 stock and want to limit the turbo lag.
Thanks for your answer
Just got APR stage 2 and I get this fluttering sound when I hit full boost, not sure if it’s a boost leak or if my diverter valve isn’t working properly (I have a diverter valve spacer in, not sure if that could cause the issue too)
Turbo flutter is what you want lol
@@ShutUpBubi no like it's fluttering while you're on the gas. like, specifically when you don't want any boost escaping
@@ballisticairsoft7070 I have the same issue. It's normally around 3rd or 4th gear maybe around 3500rpm. I can't figure out what the issue is. I have a JB4. Let me know if you find and answer because I have been looking for weeks @juulstain
I have the same issue let me know if you find any answers
@@juulstain9654 I think I know what it is. The diverter valve is only tested and manufactured for stock boost pressure. Once you get a JB4 or ECU tune the boost is turned up. The sound is boost escaping past the diverter valve because the stock valve can't hold all the boost in. To test the theory I ordered a DV+ diverter valve upgrade from GoFastBits. I'll have it installed as soon as I get it and I'll let you know.
Throttle is rattling but its not a cable drive....
So a BOV is better than a DV in terms of longevity of the engine and turbo?
not for gti’s or any tsi turbo engine. the k03-k04 turbo is built around a diverter valve. i’m not sure as far as bmw’s but yeah. no blow off on tsi turbo
Will a BOV harm the car if it is stock? Reliability wise
A BOV can damage your turbo eventually, mostly by causing excessive wear to the turbo bearing. This is not a BOV though, it's a diverter valve. The difference being that it maintains as much positive pressure as possible in the intake when shifting or coming off throttle where as a BOV venting to atmosphere does not. The advantage being better throttle response after shifting or coming off throttle by reducing turbo lag. It makes a sound like a BOV but isn't really the same thing.
Should I get a awe track exhaust for my mk7.5 gti w/ stock dp
GOODSATIVA I have an APR downpipe and awe track version, it’s a fucking hog. You get a LOT more noise from the downpipe than the exhaust. If you’re going stock downpipe, I’d just chop your stock muffler and save yourself some money. The exhaust system isn’t worth the money and trouble if you’re running stock DP *in my opinion*
@@nitsuabro9463 ok but I'm staying stock dp and I dont want to chop up the stock exhaust so awe track it is for now. On sale rn also
GOODSATIVA I’m not telling you not, just know what you’re getting yourself into. Stock DP is squeezing all that air and slowing it down. Doesn’t matter how wide or free flowing your exhaust is if the air can’t get to it quickly and fluidly. It’ll be louder than stock but it’s designed for a larger volume of air, it’s going to sound kinda hollow
also it's mostly the cat blocking a lot of sound. my catless stage 2 pop and crackle was 100x louder than my friend's catted stage 2 pop and crackle. both unitronic
@@GOODSATIVA stop being dumb. Just change the downpipe, don't get an exhaust if you're not wanting to go all out. Waste of money on an exhaust if you keep the stock dp
What if you just want the pssshhh or stutututu sound?
BOV is pretty good for that.
but it's supposed to affect performance
(you probably won't even notice the difference tho)
@@LucasHuang affect performance as in lower your power? Or do you mean reliability wise
@@scmtkings4
I'm no mechanic, but from my understanding a BOV will introduce a little turbo lag.
This is because the diverter recirculates the excess boost pressure to help keep the turbo spinning for longer when you let off the accelerator making for better power delivery upon gear changes. A BOV removes this system because it dumps pressure to atmosphere.
I also can't see how a BOV would affect reliability, but I can't say from experience as I've never had one.
Hope this helps!
Inlet pipe or DV+?
Both!
Lol the diverter valve has no effect on the feel of your pedals
I believe the #GFBDIVERTERVALVE should be done when the og fails.
but the likelihood of the stock one failing for most people is pretty slim
Lucas Huang mine just failed ☹️ getting it replaced Monday
well shit... speak of the devil
I ran the DV+ when the factory DV stop holding boost. Even with the new DV revision from Audi/VW will fail. I can only speak for two cars I had. One car factory and other with a stage one tune both with DV+. Also, you can run the DV+ with or without the main spring. Depending how you want the DV+ to work. Like anything you put into cars that is “aftermarket” may need fine tuning for your car/application.
Maintain your car and it will work like any normal thing 👍
Yes its designed to hold boost longer it works, first mod to any Volkswagen ive owned, btw the ebay clones work just as well as original 👍
Yeah... No!!! Total BULLSHIT... Have had my GTI for over 7 years mk5 had cheapos, from eBay, rkx, China no name etc always an issue (diaphragm) used forge, hks, never an issue one thing you DON'T I said DON'T went to CHEAP out on your turbo'd car is a BOV/Diverter valve!! ☝️☝️☝️ Had no idea what he is talking about ☝️☝️! So Spare the extra 100 bucks or don't drive a TURBO car 😂😂😂😂☝️☝️☝️😂😂😂
yeah idk how comfortable i'd be buying ebay/cheap stuff when it comes to the technical stuff. i'm all for it when it comes to aesthetics cause it's just looks. it's kinda like buying a phone processor vs a phone screen protector from ebay
the weakest point of all diverter valves that are aftermarket the gasket o rings suck and they leak after a while. i have the DV+. if you pull them out you will see the o ring all flatten which causes boost leak
@rankmeuptoday2119 soo the DV+ isn't worth it then? Seal flattens and it also loses boost is what you're saying? Super curious bc im thinking of buying one for my a4 and I keep reading mixed reviews
@@kylewinters8653 it’s worth getting it the dv+ they work really good but the fix to this issue was using one of my stock extra dv o ring instead of the dv+ one and get silicone maker and put it between the turbo and dv+ to make a better lasting seal. This has been my solution and it does the job
@@rankmeuptoday2119 thank you so much for the info and the quick reply. I will be ordering it this evening bro!
@@kylewinters8653 you bet
Anyone tuned there financed car?
if its financed...its yours...you can do whatever the fck you want with it...that doesn't work if its leased
nay
shhh no spoilers
It's a golf so it's fuckin slow anyway 🤣🤣
That Mazdaspeed is slow lol
NO, use the stock DV.
Why
nay
shhhh don't spoil the video lol
