Installing a GFB Respons Blow Off Valve! | Hyundai Elantra GT N Line

[@claypettitd5503]

Installed mine in my i30 nline premium about a week ago. Removed the factory valve from the top relatively easily, but tightening the hex bolts on the GFB was a PITA. Ended up removing the large diameter horizontal TB hose which made things easy. Adjusting isnt that easy when the cap is slick. Took a fair amount of skin off the knuckles doing it. Great channel Justin

Hey man how does the car sound with the BOV and is ur car the 1.6Turbo?

[@mrwill219]

I just picked one up used, 3000 miles for $160.... love that sound!

[@kz6fittycent]

Just got my GT N and I'm happy with it. Found your channel and now I'm subbed. Thanks for posting your videos.

[@JustinKelly]

Overall its a great car. Thanks for supporting the channel 👊.

[@awesomecomet3577]

Well now I'll hear you coming! 😉 The GFB valve sounds awesome man!! I kinda wish I bought a turbocharged car for this specific upgrade 😆

[@ChrisDallasDualped]

Hey Justin, where did you get those 225/40 r18 blue alloys from? Care to share a link? Thank you. Thx for the videos btw great work.

[@zoomsnipes5448]

They have this for the Elantra N. It I heard some bovs can cause over fueling, stalling and other issues. I’ve been looking at SXTH HKS forge and GFB PLEASE HELP!

[@ZrinNaidi]

how much is your pre load adjustment spring? is it 100% '+' or 50/50??

[@RobertoSantos-wx2gb]

Hello, does this car have any chronic problems?

[@OnlyPetsChannel]

Does this avoid warranty

[@curryduckandroti]

Sounds wicked!

[@JustinKelly]

Sure does!

[@joeochoa4030]

Ok ,, I just bought a brand new 2020 NLINE ... what’s this for ? What’s the purpose ?

[@joeochoa4030]

Will it enhance the performance on my car ? Or make it faster ?

[@anthonycoffey816]

I believe blow off valves are used to adjust how much boost the turbo makes before it vents. Different internal BOV springs have different stiffness which affects how much boost builds before it vents. It can certainly increase power but you REALLY want your car tuned to the boost level. Most people install a BOV because it sounds really cool. Looking at a 2020 N-line myself here soon! 🥰

[@PrinceofPeace2000]

@@anthonycoffey816 did you get one? Got my baby fluid metal!

[@Willshootz_89]

Thank you for this video man, super helpful !

[@compacheo603]

Did you adjust the valve itself on the spring?

[@jabu9]

I'm having constant flutter, not only during low rpms but every time I left off the gas. Any suggestions on fixing this? I tried adjusting the spring, my boost solenoid is working fine.

[@JustinKelly]

If you are hearing flutter chances are the valve is not opening properly and the noise is coming from the air being forced back into the turbo. I would make sure the spring isnt too tight and everything is working correctly.

[@KevMk3]

I really need a GFB for my i30N

[@JustinKelly]

I would definitely recommend the Respons if you want some adjustability. I have really enjoyed it so far.

[@adriangrosu8486]

What engine code do u have? I'm interested if it fits a tucson nx4

[@AcidOverable]

I m looking to install a valve like you did, on my 1.4 turbo. I already remap thé ecu last month. If i change the valve, i need to remap one more time ?

Hey man I have a 2021 forte gt is this same blow off valve compatible with my car? I’ve looked around and this one definitely sounds best

[@JustinKelly]

Yes I believe so but I would double check the flange.

BOV void factory warranty?

[@edycabrera8181]

Do you know if I can install it in my car if it’s a i30 1.5T-GDI 48V N-line?🤔 because I’m the info page it seems that is for 1.6..

[@JustinKelly]

That powertrain is very new to the market so it may be unknown at this time.

[@p_a_rivers_projects]

Would adding this or other aftermarket parts effect Hyundais warranty?

[@MrTherandomvidsguy]

Yep. My dealership told me they can void it if they want. If not, have them install it. BUT, they'll still have to prove that specific part ruined your engine.

[@ryanpatterson336]

How do you know when it’s 100 circle or 100% vent or 50/50?? Got one for my 21 Elantra nline

[@JustinKelly]

You can't really tell when it's installed per say. That is one complaint I have with it. I had one off the car a couple weeks ago and it wasn't even when it was spun so it was 50/50 closer to one direction or the other if that makes sense.

[@Meniodakis]

Hey Justin I bought myself the GFB Mach 2 Question any thoughts on upgrading the intake on these cars I was consider doing a drop in k&n panel with a big mouth

[@JustinKelly]

That's a good combo for most cool intake temps (not a huge deal with intercooler) but may help a small amount.

[@Meniodakis]

Thanks mate

[@hunterhiggins6435]

what size hose came with your GFB if you don't mind? thinking I need a longer one for my bov

[@JustinKelly]

Great question. I don't know the diameter of the top of my head but it was small.

[@ivangentili4760]

Hi, do you know if the engine is the same 1.6 t-gdi 204hp that mounts the Kia Proceed gt?

[@JustinKelly]

I am not exactly sure if it's the same fitment. GFB should have compatibility listed on their website.

[@yeahmate94]

How do you get the SUTUTU sound? Like a fluttering sound?

[@JustinKelly]

Most of the time that is Turbo flutter I believe and its not the best thing for the Turbo.

[@Aerondighteternal]

You actually don’t want that. Although I think it sounds cool it’s bad for the turbo

[@sahan2860]

@@JustinKelly But how do you get it

[@Viikfacee]

@@sahan2860 buy an air intake system

[@sahan2860]

@@Viikfacee I assume you still need a blow off valve with set to full atmosphere with the atmospheric vent plugged (closed)

[@JC-de2rd]

Dosent this car already have a blow off valve stock? Sometimes I notice a blow off sound when I release gas.

[@JustinKelly]

Sort of. Its a recirculation valve which vents back into the intake system. I consider BOV to be venting to atmosphere so you actually hear it. You can sort of hear the stock one but its not meant to be heard.

[@HarryTwatter]

oh I'm getting this for my Forte GT!

[@andrewhelou89]

Does the cerato gt have an air flow meter? Will this hurt the engine or go into limp mode

[@JustinKelly]

I don't know for sure but you should be fine

[@rastin8194]

How hard do you have to twist to adjust? I keep twisting but I’m not able to make it move

[@JustinKelly]

Off the car not very hard at all. On the car it is a little tricky getting your hand in the right spot but not difficult. Just remember it only turns so far in both directions.

[@sahan2860]

hey man, any ideas on how to get it to flutter. i.e how much recirc do we need or do we need to block off anything

[@roylaprattep]

It's the intake that gonna cause the turbo to flutter.

[@readyplayer5661]

Flutter is the result of not having any blow off valve. You would delete the blow off valve all together at both ends (pre and post turbo). It's then enhanced by changing the intake pipe to a metal type.

[@leodai8620]

I’m assuming this works on the veloster turbo as well since they re both 1.6T?

[@JustinKelly]

Yes it fits the 2019-2021 Veloster Turbo

[@amcornothing3720]

And does it fit 2021 sonata 1.6t right?

Was there any difference in performance or throttle response?

[@JustinKelly]

Not that I could tell

[@mkvftw]

Will this work for a 2020 Elantra GT base model

[@JustinKelly]

No because naturally aspirated engines do not have this part.

[@olishlt4206]

How you setup for 100% atmo?

[@JustinKelly]

Turn the collar to full open. This one is fully adjustable just by turning it.

[@teeztoyz]

Justin would you recommend this mod if the goal was better throttle response? I don't care about the noise so I would probably go for the Mach 2 rather than the Response. GFB claims 30% quicker boost and better throttle response but that is for the fully recirculating version which I don't know if you've run yours fully recirculating but would you agree with their claims? At $240 I want to know if it's worth the investment.

[@JustinKelly]

I dont think you'll get 30% better throttle response out of this part unless your stock BPV was failing. Maybe its a little better but I didn't notice anything throttle wise that I can recall but my car is pretty new.

[@VanillaWahlberg]

If you're under the impression fully recirculating will improve throttle response, keep the stock valve. It already fully recirculates back into the intake. This would be a pointless upgrade.

[@JustinKelly]

@@VanillaWahlberg The stock valve is rubber and can leak or fail over time. It would still be an upgrade even if its doing the same function.

[@VanillaWahlberg]

@@JustinKelly Very true. Although if not needed and still under warranty, can give them a reason to deny claims. Since they cause so many CELs on the Elantra Sport I won't be getting one until I get closer to the end of my warranty. They do no damage, but a CEL is the last thing I want to deal with in CA. :P

[@JustinKelly]

@@VanillaWahlberg No CEL here. I think if it gets bad enough there are drivability issues along with the OEM valve which some people get fixed and others dont.

[@waterhi]

I assume if you roll into the dealer with this installed you can kiss warranty goodbye? I just bought the exact car you have and I'm worried about mods/warranty. dealer basically said even a CAI would screw me.

[@JustinKelly]

I would find a new dealership if they think an intake will deny you warranty coverage in any way.

[@theflukey4114]

No. I work at a hyundai dealership as a service tech and we typically don't care about mods as long as you don't open up the engine or overwrite the factory tune. Chip tuning is fine, since it isn't permanent. As long as the mods don't cause any parts to fail, you'll keep the warranty. It just depends on the dealer, some are mod friendly and some aren't.

[@theflukey4114]

They have to prove the mod you installed caused a certain part to fail. You could install a CAI and maybe MAF fails or the turbo starts having issues, they have to prove the mod you installed caused those to fail tho. And a CAI is easy to install and remove. Just swap it for the factory one when you bring the car in for service.

[@Roadsurfer2k11]

@@theflukey4114 I know the dealership I went to for service definitely will void. I had severe oxidation on spoiler to point of near cracking. The service manager wanted it in the stall twice to slap essentially Armor-All on it so they can slide on painting it under warranty. And after 2 hours of that, it was the manager decision. Rediculous for something obvious. Too much info im reading so far regarding if bov's deteriorate turbos, I don't know what to believe. I posted videos (on this account) yesterday on the bov spring adjustments from stock to 3 turns tight and saw not much difference. But according to GFB video of their engineer showing spring adjustment, he mentions at end it should only open about 3mm Bov spring setting kzbin.info/www/bejne/gZiqg5mIa8-nY8U So I need to contact them and find out what's a normal, safe setting. My piston open up half way under a 4k rpm load

[@VanillaWahlberg]

@@Roadsurfer2k11 If the BOV is opening mid boost, WOT, you need the spring set to a stronger pressure. The thing is though, all these 1.6T's don't seem to like anything but the factory diverter valve. Not really sure why other than maybe because the spring is so soft and lets boost out at the slightest decrease of throttle pressure.
