- In this episode, we dig into our Alfa Romeo Giulia Quadrifoglio and fix one of the most common issues on these cars, boost problems! The factory blow-off valves are made of cheap plastic and are known to start leaking and cause issues with boost and throttle response. We take apart the factory units and install both the GFB DV+ BOV rebuild kit, as well as the Weistec External Blow Off VTA adapter. Let the chuchu and sutututuu commence!

Y’all have inspired me to tune my own Alfa Giulia QV!! Goodbye FCA warranty, hello performance!!!
This Is how I set up my 2017 Quadrifoglio, works great!
Open blow-off valve instead of recirculating means you loose boost pressure with every gearchange or throttle liftoff. The original plastic valve actually very rarely breaks too, its good quality
In an automatic, you only blow off if you lift... if you lift you were losing boost anyway. On a manual you might have a point but who cares because it sounds cool 🤣
What are all the mods you did on this car? Did you try a 60-130 or 100-200 time? I would love to do these mods on my Stelvio QV
Man I never knew that the Giulia Quadrifoglio has very good tuning potential
Makes this a very fun car tho I wish we had one with a stick shift
Yeah I've been pretty surprised with how nicely its been taking the mods. The drivetrain seems pretty robust! A stick would have made this car perfect, but the ZF8HP is a great auto for sure.
Manuel is only in europe
I installed the Weistec adaptors on my Stelvio QV. It wasn't as easy as your Giulia QV but I love the sound. I also installed the Ideal Race CF intake. A very worthwhile modification in my opinion.
They're still on. No issues and very unobtrusive sounding. They're a good match to the Stelvio QV. Unfortunately I'm relocating to Puerto Rico on the 25th and I voluntarily surrendered the Stelvio to the bank. I'm going to look into getting an RX-8 in Puerto Rico, rotary engines are the thing back home.
I left them on. I had some warranty repairs done at the dealership and now I can't open the hood. The techs don't know what they're doing.
I heard for the stelvio qv you would have to get under the car to access the Bov location for install?
I wish my arms were thinner but I was still able to get them from the top. The Wing Chun did come in handy, it's not easy doing it from under either. The easiest way would be removing the front bumper. My arms looked like I fought off a raccoon afterwards but I enjoyed the results.
@@robertoruizantonetti6385 is there space to also fit the GFB DV+ in the stelvio qv?
How did you keep the DV+ pistons from falling out when you installed them without the Weistec adapters?
This may be a dumb question but how do you get the air to shoot out like in the thumbnail? My son really wants to do that to my QV like in the f&f. Plus looks neat. Thanks
Nitrous tank with purge kit setup
I love this car
Will this work for the 2.0?
I have BOV adapters I never installed bc Alfa would void the warranty on a brand new replacement motor...
Did you have to get new bolts when combining the GFB and the BOV?
Are you guys going to add a body kit with spacers or?
I have never had any problems with the valves. Up to 2.5 bar of boost and zero issues.
It sounds amazing, looking to due this same project. We're you able to find out what size screws you used? Thank you.
Yes, they were about 80mm cap head bolts!
I bought both based on this video. Does the label on the DV+ say “fiat/bmw”?
Was it just me, or did it sound like the BOV sound too abrupt when it closed?
I think it's because it is electronically actuated rather than by vacuum.
so with both, you are recirculating 50% and 50% atmospheric?
Yeah! Great vids!!! 🇮🇹
Since it uses bypass valves instead of a typical blow off have you noticed any dips in power? Or delay in throttle response?
None at all! Because the car is fully run on MAP, it has no issues with the change in air volume.
@@albonfilms Is that due to tuning? So is there a possibility of dip in performance on stock setup?
Waiting for that “hnnnnnnnnn-so-to-to-to”
Oh he did the thing 🤣🤣🤣
Sutututu
how has the car been after the tune any problems? i have a 19 QV and would like to do a catless and tune
Haven't had any issues! The car drives really well in all conditions, and has been really reliable!
I get why some people might like this but tbh I would rather hear that Ferrari derived engine in all its glory through the exhaust than hear the whooshing noise. Great video nevertheless
I installed the forza valve bypass after watching your vid. Thinking of putting the xpipe on my QV. Would love to hear your thoughts on it.
I think the X pipe helped make the tone a little bit smoother, but honestly it wasn't a huge change. I'd probably recommend doing downpipes first if you haven't done that already.
@@albonfilms awesome thanks, glad I asked
Straight pipes? Great car!
I did hit that like button though
Great video again
I'm trying this
on my quad, what size/length screws did you end up using?
I'll have to go back and check, I ended up buying 3-4 different lengths and then choosing the one that fit the best.
so what lenths you get?
@@albonfilms
Awsome job will this pass smog with the changes you made?
Not sure about California smog!
Sounds nice!
It's not the most sonorous but definitely an agressive sound!
The opening of the blow off sounds good but if it‘s connected to the intake, how does intake air not come out of those blow off‘s now?
It only opens when intake manifold closes and makes vacuum.
Elyas got it! They only open when the throttle plate is shut and the intake manifold no longer is drawing in boost. These are electronically actuated too, so they open when the ECU wants them too.
With cat less downpipes do u think It’ll pop up the check engine light?
Without a tune, definitely. With a tune it should be no problem.
@@albonfilms ok thank you!
Mine doesn’t work when it’s in neutral only when I drive it it makes the pusssssssshhh (only put the blow off valve) I don’t have a quad but I have the TI SPORT
Whats next for it ?
WE NEED EP12 PLZ 🤔❤️❤️❤️❤️🙈
In the works!
Weird, the bov is electronically operated and not vacuum? Maybe it's not weird, I dunno, I have old cars lol
Yeah, first time I've seen this sort of system! It's interesting though because it keeps the BOV closed on upshift for better response in the next gear. Cool system for sure!
@@albonfilms makes sense, and explains why the bov noise is so unnaturally abrupt sometimes. Really cool tech, keeps that boost on tap.
@@robertsixto6320 Most new cars have electronically controlled BOVs, the Supra has it too.
What happened to the Alfa now 3yrs later
Any issues since installed?
None at all!
What are all the mods you’ve put on the giulia
Catted Downpipes, X pipe, Tune, and the Bypass Valve setup. Oh and the Forza exhaust control
Is that exhaust stock?
It has catted downpipes and an X-Pipe midpipe, but stock muffler!
So the VTA has literally 0 negatives associated on a stock quad?
Haven't had any issues with it as of yet
2020 supra content
It's coming! Working on a few things!
Sont pressure him man
take a 70-80k Italian car and ricer it out? lol like a Subaru... to each their own. nice exhaust though. what tune did you do?
Absolutely, to each their own! The tip in throttle response increase of fixing the poor quality OEM valves is well worth it to me. Plus I like when turbo cars sound like turbo cars. The tune is from Ideal Race. Thanks for watching!
You have no taste in cars lol another bmw fanboy
sounds like manual grinding gears.
nice
Get a go pro under that hood
That would be dope! Good idea.
Say hello to CEL.....possibly as ECM looks for that air in the intake...wisetech sounds like huge quwiffy. Lol
It doesn't use a MAF, the ECU calculates everything based off of speed density. Venting blow off valves will not affect anything.
But why didnt it make sttutututututut?
These bypass valves are electronically operated so they just open once instead of fluttering like a mechanical valve.
Oh now i get it thank you!
Gypsyx fix "Alfa";easy with gears boy
Bellissima auto il motore di origine Ferrari e lo stesso motore montato sulla Ferrari V8 California. Con due cilindri in meno!!
Hey @albon here you go. And - obvious tho it may be - he’s not wrong:
Beautiful car, the original Ferrari engine is the same engine mounted on the Ferrari V8 California with 2 cylinders less.
In related news, “il cielo è blu.” 😜👍🇺🇸
Impressive... for Teenagers...
👍
Noti squad
❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
External BOV’s are stupid!
I can't believe you haven't answered me 😒 fuck!
Wish it fluttered
Agreed. This sound is nice, but I prefer the JDM style flutter!
Is this actually Texas cos I'm from Europe and I was expecting everyone to have more fingers than braincells
Hahahaha, not all Texans are bovine!
What would make you think that 🤔
🙄🤦♂️
That car sounds crappy with those mods I would rather get some electribuc exhaust dumps
