So wastegates keep turbo speed steady or do they slow down the turbo?
You blew up somebody’s Porsche on the dyno? Lmao
Best description for how they work on the interweb in my opinion! Nice job guys
Very informative. Thank you!!
Thanks for nice and easy explanation 👍
wow, so informative! thank you so much :)
I have plans to turbo my Miata. Watching this video basically tells me that I don't need an external wastegate for an engine that is only going to be making about 250 horsepower at the wheels.
Super good video thank you!
Great video!
Hey Paul... fyi you wrote wategates in the description of the video
Hey man, I am wanting to install a catless DP on my WRX, but I am scared of boost creep. What else needs to be done to convert from an IWG to EWG? I am upgrading my stock turbo to an STI one while doing the DP as well. Is it better to just buy a High Flow Catted Downpipe instead of trying to install a catless DP and converting to EWG?
Where did you get the exhaust manifold?
Thank you
Nice video! i have a little issue with my Td04-19t on my saab 9-3. In 2nd and 3rd gear it does have 1.6 bar all the way up to redline (sometimes rarely it holds 0.5 bar when i floor it wich is base boost pressure) Yesterday i went for a top speed run and a 60-120 test but in 4th and 5th gear in high rpms is only has max 0.5 bar. Barely could get to 120 with 330hp at the crank. My previous setup had a T25 widh about 240hp which got to 150 mph and ideas?
Love this series. I have a MKV FSI as well. Do you guys plan on installing oil temp and pressure gauges on this car? What's the best/most reliable place to tap for a reading on this engine? Any sender and gauge recommendations? Keep up the awesome work!
really appreciate the feedback!
is it of you want to use external wastegate, u have to take out the internenal wastegate and welding the 'flipper' in your turbo?
are you guy gonna run a open dump thru hood or just under the car .... im building a same car right now and i can't decide thru hood or not haha ... im going with the gtx3076 external wastegate and custom open dump
What happens if you don't connect the vacuum hose to the wastegate on that first turbo set up ,
so if im aiming for 400-500 whp external is overkill or kinda a essential prevantative
is a good video and you know i own a beetle 2000 1.8 turbo but the turbo doesn't work and sometimes take out some white smoke can you tell me why and thanks your videos are awesome
Most likely a blown/ bad turbo... Id check and see if the turbo has any shaft play... also keep checking your oil
Hi, the actuator for my wastegate is not holding pressure. The wastegate flapper is shut closed. But the actuator rod does move and open the wastegate when I applied pressure to the actuator. The flapper has no play and sits tight. Can a stucked CLOSED wastegate flapper cause P0299 code. I am getting a P0299 with closed wastegate flapper. Is this possible? Any help would be greatly appreciated. Thank you
What about a internal wastegate on a small PSI scale say 8 PSI on a motorcycle???
Which internally wastegated turbo was the porsche (that blew the engine) using? Without being too blunt, if you don't or can't name the brand, it makes it hard to believe any successful products you might mention.
Are you guys in NC? If so what part
Could an Mk7 gti use a External?
So does this work as a screamer pipe?
Are you guys doing some noise cancellation or anything with the sound in post that causes the audio to sound a bit muffled or bad?
Yup we have to as this shop has lights that have a nasty hum that would drive everyone nuts otherwise
+xReptarMuffin yes this video was shot in a shop that has lights that have a loud hum to them. While compensating for that isn't perfect it's a ton better than that hum that would literally drive everyone nuts
Can you atmosphere dump and internal wastegate?
Bro can u tell me what is used for? Please
BFR needs to add some VW stuff to their website.
Ed Mathews while I do enjoy me some quattros (I own several old 5cyl cars and two D2 A8q), there are plenty of other VAG shops in our area and we are completely overwhelmingly busy with Porsche work. If we added VAG services I'd have to buy a bigger building!
Who else is here because of the new 2022 Tundra waste gate issues 😑.... I'm going back to the 5.7L V8 asap !!!
Similar like my tractor use it lol.
Very common now since there going so small in litre size you need a turbo to make any power out of the motor ..
Thats not the point. Those all have internal ones.
yeeeeeeeeeeeeeeeeeeeeeeee
Or maybe even watergates
why not show precisely how to tune up/down the turbo pressure on the first turbo set-up..??
basically guys you want a ...
38mm T25
44mm T28
60mm T30 and above
I use a 44mm tial on a 3076R
Is it okay? 🤔
@@javiertaycg956 it will be okay but you might have to up the spring rate.
@@cetGT3 wow thank you for the reply 🤜🏽🤛🏽
you know the thumbnail says "wategates" right?
What the fuck is a wategate?!!! Lol giving you a hard time 👍🏻
Still not really sure how a external waste gate works?
Bro i need to know what is this? Pls
👍👏👋
I’m so stupid man. I don’t know wtf either of them just said.
What you said is incorrect. You CAN have external waste gate on the stock set up, you just need to weld the flapper shut and weld a wastegate pipe off your manifold or rear housing
if you weld a wastegate pipe off the manifold it's not stock anymore
@@bigsalo8598 but it can still be done with the stock manifold.
Hello @imTriiBz
I found your comments interesting
What, do you mean by weld the flapper ?
So, can I have external WG with the stock internal WG and both works together..
Like when over boost the external WG opens, otherwise the internal do the job…
@@vanhabib10 no he meant you weld the stock on so it won't move anymore and completely fabricate your stock exhaust manifold with an extra pipe to hold an external wastegate.
I would debate against the comment regarding larger turbos and higher HP needing EWG over smaller ones. Boost creep happens on any size Turbocharger depending on the circumstances.
Great video otherwise though.
Terrible visual explanation. People can't read your thoughts.
