My Process To Find 1.8T Boost Leaks Fast! | & New TIP

In this video I finally upgrade the turbo inlet pipe on my TT. This is a critical part in the turbo system and it tremendously enhances the look of the engine bay. I am super excited to finally replace this part as it has been on my list of Todo's for a while. I have gotten alot of comments asking how I find boost leaks, so I thought now would be a great time to go through my process of how it find them on the 1.8 platform. This isn't a perfect method, by any means, but it's a great summary of all the issues/common problems that I have ran into. Hopefully you all find it helpful if you run into similar issues.
We are getting so close to 1000 subscribers it's actually insane.
I can't thank you all enough for the support. :)

Would love to see videos for installing a new boost gauge or any and all other parts. I bought my TT a few months ago and have never had a car with a turbo before so this is all a bit new to me and your videos have been super informative and helpful.

[@King_Henry]

Awesome as always bud. What a great overview and so well-spoken.

[@kevinsilveira6189]

Great video! Im currently on the hunt for a boost leak on mine aswell, my TT has lost some power and also holds the revs for a few seconds instead of going straight down when I shift gears. Excited for more videos to come!

[@HunterDirection]

I am glad you liked the videos and are excited for more. The support means alot to me. It's a really fun car to work on. Thank you!

[@JGZ114]

These videos are so helpful! I recently bought a 225 bam coupe and this is the channel of dreams! From the uk and hoping to replace all these hoses asap

[@andycharger]

Great content buddy. Boost leaks can be a real pain on the TT. The TIP often goes soft and causes issues. After all, these cars are many years old. I just dropped you an email about a project between our channels ;)

[@georgestreisel7920]

Excellent video!

[@rushardmiller9229]

Great video!!!!!!! Keep up the good work

[@HunterDirection]

Thank you so much for the support!:)

[@crikeymikey3691]

Another interesting video, Hunter, thanks. Your attention to detail does you credit. I especially liked the diagnostic flow chart. I have another recommendation for you. Adjustable rear control arms are another transformative modification to the TT. There isn't enough adjustment of rear camber angle otherwise, meaning the car's chassis balance is always towards understeer. Most people concentrate on power mods but the greatest deficiency the Mk1 TT suffers from is in the handling department. The HPA controller and the increased negative camber at the rear have improved my car's handling beyond belief. Congratulations, in advance, for nearly 1000 subscribers! Best regards. :-)

[@moncier77]

I installed on mine. Big difference

[@crikeymikey3691]

@@moncier77 All the TT's grip, in standard form, comes from the front. Most of the weight is there, and the quattro system is asleep much of the time meaning it has all the worst traits of a FWD chassis. The extra negative camber at the back brings the rear into play, effectively dialling out some of the front end push, of which there is plenty otherwise. I suspect US and Canadian owners are less bothered about handling, but for UK and other European countries it's more of a benefit perhaps. If you get an HPA haldex controller (somewhat ironically, a Canadian company) the transformation is complete. Keep running with wind! ;-)

[@HunterDirection]

I am glad to hear someone liked the flow chart haha. I always find procedural processes helpful so I was hoping someone else would too. I really appreciate the support. I also like the sound of adjustable control arms:) I will start looking into those and try and get them to show up when I get the coilovers. The HPA controller also sounds like a really great upgrade! Thank you again!

[@Al-qv5vs]

Another good video, thanks. Def felt a small power increase with a larger tip. I would like to see a boost gauge install video.

[@HunterDirection]

Thanks for the support. I am glad to hear you liked the video! In that case I'll go ahead and order up a nicer boost gauge:)

[@stevesloan6775]

Excellent video! Easy to watch. Good advice regarding isolating the leak. Love my Mk1 TT… Lols… My selector fork just broke in my 6speed….Gulpppp!!😂😂😂 I’m removing the gearbox myself.😐😐😐😂 Looking forward to your next upgrade video… “Gets the juices flowing”

[@HunterDirection]

It makes me happy to hear you enjoyed the video! Sorry to hear about you having to remove the tranny. I'll be doing that sometime when I have to replace my clutch. Thanks for the support!

[@stevesloan6775]

Ha I put in the latest version of selector forks in. 1st-5th selector forks fit, but you still have to use the original reverse and 6th gear selector forks. The new versions are full steel and robot laser welded. No rivets holdings different incompatible materials together, like bronze alloys and steel.

[@raggamodz9377]

Boost gauge tutorial 👍🏾💯

[@HunterDirection]

Sounds like a plan! Just got all I need ordered up. Thank you for the support!

[@mega__00f41]

Love your videos, they are so useful. I am currently having some boost issues and replaced my n75, however since replacing the n75 it has lost a lot of power and feels like it might even be in some kind of limp mode. Would appreciate any advice if you get the time 👍🤞

[@HunterDirection]

You sound like you're on the right track. Depending on what n75 you put in they have very different rates they ramp up boost. I know the "race" n75 has a tendency to make the car think it is overboosting and toss them into the 5psi limp mode. Do you have a tune or boost gauge?

[@CarChris82]

I put the badger 5 tip on which is much bigger than the forge which I was replacing also a pro ram filter is the biggest but great vid and some nice mods mate 👍 ps if your going bigger turbo or over 300bhp get forged rods fitted

[@HunterDirection]

I am planning on building a fully forged engine for the car eventually haha. When I can get my hands on one that is lol... Thank you for the support!

[@CarChris82]

@@HunterDirection good stuff mate you know those standard rods are made of cheese 👍im going to get mine forged this year

[@davidross-oo2vh]

That lil car is tough looking.

[@iasonstv5907]

I recommend you to replace your front grill. I had the same one as you have, and replaced it with the facelift one (the one with the 3 spokes). I painted it completely glossy black, with the Audi rings black as well. It makes such a big difference. To replace it, it's said that you need to remove the bumper, but I actually managed to do it without removing it. You only need some acrobatic hands and reach from the bottom cooling trim.

[@HunterDirection]

That sounds like a fantastic idea. I will try and find one soon so I can put it on while I have the bumper off for the front mount:) thanks for the support!

[@MarkMyWordsXx]

You had the same one before you changed it. You mean the "stock" grill that comes with the car? ....me too...

[@ExpoPerformence]

I think I have a massive boost leak on the big inlet pipes thanks for the video makes all the vacuum (19) but as soon you build boost it holds 0psi

[@rushardmiller9229]

PLEASE!!!!!!!!!!!!! Do a tutorial on boost gauge install.

[@HunterDirection]

I will get one on the way:) people seem to want to see one so its a great excuse to get a nicer one. Thanks for the support!

Buddy you did 4mm and 8mm vacuum hoses, we're these dimensions internal bore measurements, ps I have a TT and am gathering parts for a big rebuild fortnight soon. Love the videos...

[@HunterDirection]

I believe those are the inner diameters. I will double check that for you though. Sounds like you've got any awesome project! I am glad to hear you like the videos! Thank you for the support.

[@jamespinkerton1550]

@@HunterDirection Gathered some original parts from oil filter to crankcase, a few parts obsolete now, 20 year old car have to improvise a little, those pipes 4mm and 8mm got to he internal dimensions...be so kind and check your invoice for me...it don't need them ATM but building a stock pile of new parts for some fun in the sun soon...

A bigger tip for a left hand drive wont work without modding some stuff on the brake booster . I tried on the s3 , didnt work. Had to go to a forge inlet.

[@HERMIR]

How do you prevent the cold air intake sucking hot air? My engine bay gets hot, so I'm afraid to put a cold air intake, and how do you detect boost leaks without a gauge? This audi is my first car, so I don't know what to look for or feel the loose of power

[@brianchoi86]

I have cooling fan issue with my mk1 tt 225. Until now I replaced thermostat coolant temp sensor cooling fan switch. All these parts are aftermarket. While checking temp 49C temp goes up to 104 or 105 and fan turns on.

[@brianchoi86]

When A/c is on both fans are turning on. I searched low speed fan should turn on around 85 to 90 C' and now I am about to replace cooling temperature module. I remember watching water pump impeller fail video but it was already replaced and thermostat opens fine. Do you have any idea what could be wrong?

[@moncier77]

Was your water pump impeller replaced with a metal one? It sounds like the green temp sensor.

[@brianchoi86]

@@moncier77 I do not know about impeller type cuz previous owner got it replaced at shop. I could call them and ask but it does not over heat. Goes up to 104 or 105 and fan start to turn. I got aftermarket green temp sensor already.

[@andyknowles666]

The oversize TIP makes a massive difference. Creation Motorsports do a really good one. (Not sure about US shipping though)

[@SATXe46]

Did you buy your vacuum hoses as a kit or did you piece them together, looking to change all mine out

[@dankasamatsu]

could you explain me where the under pipes of the manifold should go? Im not sure if I have them swapped

[@griftor2345]

Mines is only -10 vac on start up and only boosts to 10 psi in 1st and 2nd but takes ages to build up to 22psi in 3rd but will get there, It does also flutter…. Do you think that’s just a small boost leak coming from the diverter valve side of the vacuum system?

[@HERMIR]

Do you have any tips do find problems on the n75? I bought new valve n75 but vagcom still gives error code. I have the fwd 180 version

[@jungillestt02]

I just got my mk1 180 quattro and was wondering how to install a boost gauge, I've seen they make one that fits into one of the vents. I have zero idea on where to start.

[@HunterDirection]

Sounds like you have an awesome car on your hands! I've actually made a video on boost gauges for the tt if you want something that will get you pointed in the right direction. I hope it's helpful. Thank you for the support. kzbin.info/www/bejne/qKScZniJarxsoZI
