2 Turbo Blow Off Valve Upgrades on a 2015+ Mercedes C300 W205. Which should I keep?

In this video, I remove the stock OEM diverter valve on my 2016 Mercedes-Benz C300 W05 and upgrade to 2 different aftermarket diverter valves. One is a standard aftermarket diverter valve. The other is a aftermarket blow off valve. Which one should I keep?

[@shaneomac4046]

I’d try and use a oil if you can. I know a number of people use sewing machine oil and hydraulic oil when rebuilding bov and Installing recirculating diverter valves it holds up to heat and constant movement better. Wd40 will lube components but it also attracts debris that can cause premature wear. I’ve seen a few bad cases where the Dv+ gets f***ed because it is brass and without proper maintenance (cleaning and lubrication) it starts to wear and you can end up with metal shavings going through the intake.

[@thomaslibonati]

I want the version with the blow off valve. I am planing on getting a GLA and I am already getting ideas.

[@davidijames_]

I purchased the DTE Pedalbox about 9 months ago, but I must say this GOFASTBITS BOV is amazing. This would be the first perf. Mod I would do to a c205.348 . It's it is amazingly responsive now especially when have the pedal tune on Sport +++ .RE the BOV it was very hard to get it to click in place. one side would click and the others would come up. Initially I thought it was 0.25 mill out so got out the digital calipers. GFB should really include (IMO) some small shims washers as there is like a 0.25-0.5 ml spacing all the way around and when you do up the bolts it causes the OEM DV to pull down on the corners wish I don't like as naturally this is causing extra stress on the plastic.

Where’s all the obviously I get paid to say this shot nonsense??? Holy shit... is this guy ... a genuine content creator?? Holy fucking shit. So basically, you were a bad guy in boyz n the hood and not you’ve turned yourself around and made honest KZbin videos. Well done sir, well done 👍

[@TheFlexxGarage]

Ummm...first of all, dope image for your avatar pic. #TeamSubzero. 2nd...I have no idea what you are talking about but I’ll take it as a compliment. Haha I don’t BS in my videos. The most I will babble is in the beginning of my videos when I tell viewers what I’m doing, what I’m doing it with, and why I’m doing it. That’s it. No point in giving them my life story for the day. If people wanna see a more vlog style videos with fluff, that’s what my R8 videos are for since that’s entertainment videos and not “how to” videos.

[@blizteredthumbs7911]

@@TheFlexxGarage ha, it’s a compliment buddy. Which part? One was meant as humorous and the rest complimenting... And fist bump 👊 at team sub zero ... I fight on Xbox, do you partake? Xbox or ps? Son has it on pc too. Ok, so to explain from my non bullshit autistic perspective. Let’s say I search ‘how to put in a thumb tack’ could you imagine a video longer than 30 seconds? No me neither.. but 99% of you tubers make a 10 minute video to do nothing more than waste my time, annoy me, frustrate me having to skip parts etc etc, it’s so fucking transparent bro. I mean even you do a few cut shots to explain something but it’s not unrelated. Keep it going man, I appreciate your clips. Personally, I don’t subscribe to 99.9% of you tubers because of the transparency mentioned above but seeing as I do find your content productive and you actually communicate with your comments.. you my man are cool in my book and I’m even going to put the dreaded subscribe button just for you. Only because you deserve it ✊

[@blizteredthumbs7911]

Done ❄️ Sub zero ❄️ approves lol

[@TheFlexxGarage]

That’s exactly why I started my channel almost 4 years back. I wanted to show people how I mod a car without no BS. Most youtubers want to hit the 10min mark because they think the KZbin algorithm will promote their video cause it’s longer. And that should get them more subscribers. I don’t care about that and that’s why most of my videos are under 5mins. I don’t really care about subscriptions. I care about creating good quality content, interacting with positive viewers and focusing on the love of the mods (not just trying to grow my own channel). If I make good content, the views and subscriptions will come but they won’t dictate how I create my “art”.

[@TheFlexxGarage]

Yes I have sponsors but 99% of the products I bring to the limelight are great and most people don’t know about it. So I use myself as the test rabbit for these products and bring them to peoples attention. And they can decide if they like the mod or not and they can decide to buy it or not. The sponsors definitely help my channel and allows me to keep making more videos. And I’m 100% transparent about them paying me in all of my video descriptions. My parents always taught me to always be fairly compensated for the quality of my work. Some people think me being sponsored is a negative but for the info I bring and effort I put into making my videos, I deserve some kick back in the sales of these products while everyone is getting my content for free. And trust me, it’s not a lot of money. I’m not quitting my day job anytime soon.

[@Entertainmentinc1]

responsiveness does not increase by changing chargepipes or intake tubes, you need to make tuning changes to adjust responsiveness. also people if you stock car us below 100k miles you dont need an aftermarket diverter valve, it wont do anything, you might aswell spend that money on somewhere usefull

[@grant1224]

would this fit w205 ‘18 c43 amg

[@TheFlexxGarage]

No, only turbo 4 engines

[@unfateddt]

Do a video comparison for Forged BOV and Turbosmart BOV. Those are pretty "hot" right now and performance wise, it feels better than GFB.

[@TheFlexxGarage]

No point. This is a c300…not a high performance turbo car. Your spending money on something that does almost the same thing. A bov is not gonna give you that much of a performance difference regardless what brand makes it. A hybrid turbo swap or a tune is what really changes things for a c300. Everything else is minor. I rather stick with GFB that I know that is affordable, lasts long, and does what I need it to you. Again…this is a 4 banger c300. Lol

[@newtongsm]

What mean leaner explain more have you install what product be clear ?

[@Acrimoniousbear1]

Likely the car would be running RICHER if he was using the valve that vents to atmosphere. Since he chose the recirculating valve the car likely is seeing no change in air flow. All air the MAF accounted for is still within the system. Basically no tune should be necessary

Throttle response isn’t really that much affected. Boost is affected cause power keeps kicking between shifts cause the car doesn’t really need to start over on building boost.
