hey guys, this is what happened, i was driving and after a boost the car made a loud bang after i changed gears, then the car wouldn't hit boost anymore as soon as it revs up it hits a limiter at 3k revs then dies.

I checked all the intercooler piping that seems all good, i thought it was the AFM because when i unplugged it then the car idled fine and doesnt stall, then when i plugged it back in the car starts then drops revs slow then stalls,

so i bought a new AFM put it in and it started going all good then after 2 minutes done the same thing and stalled,

Car is an r34 gtt.

Definitely sounds like intercooler plumbing. Have done the exact same thing a few times. Make sure every single clamp is tight as Jez said, don't just look at them and assume they are tight. If they are all good then my money is still on a vacuum leak, but seeing as it happened after boosting then I am quite sure you will find it is the clamps.

thanks for the advice ive found it now the manifold was cooled down, the elbow silicone hose off the turbo to intercooler is rubbing on the manifold and the heat must of put a hole in it then it must of burst and put a 8 cm rip in the back off it. :action-smiley-069:

      New fix for low tyre pressure from bmw

      I believe Unimog is the only vehicle that has it (from the manufacturer). I haven't seen aftermarket permanently connected kits, but I haven't looked either.

      Ha ha ha, can't overthink when exhausted... Oh how I wish I had that power! I can be absolutely dead set shot, and my brain will still go "we need a good 3 or 4 hours to just think about everything and anything before you may sleep... My biggest thing is making sure I give myself enough sleep. I don't operate on even 7 hours of sleep! I attempt to give my body 9.5hours sleep a night to be able to function. I don't sleep the whole 9.5, but I need to make sure I offer a big window. I also take a single supplement, which is to help with long term health, and fighting inflammation, and I notice it helps massively. Especially me sleeping, and just less "achey" in the body. Have also kicked sugar, and gluten. A majority of people with ADHD don't go well with gluten. It causes a really interesting natural opioid overdose in the brain, which causes bodily issues and sensory issues.

      Yeah that's what I meant, permanently connected not manual

      Yep. But typically that's just run a hose down to the tyre while stationary.   Oh and the Unimog will automatically air up and air down tyres from the onboard computer for you too.

      There was a good video somewhere, maybe Kurzgesagt that linked physical activity to ADHD/Anxiety/Insomnia etc. Basically the body WILL spend energy doing something if you don't spend it doing anything physical. It isn't fun, but I personally have noticed I've never been overthinky, or unable to sleep if I'm physically exhausted from doing a lot. The musings around it seem to indicate that this is one of the reasons/mechanism that physical activity improves mental health/wellbeing etc, by more or less not using that 'extra' energy to overthink, be anxious, inflammation, etc. There's also the fact that every obnoxious exerciser ever says it's great and helps which is extremely annoying. Like people who say the same thing about travel being the best thing ever. I mean, they clearly are, but blah. I started doing a LITTLE myself (think 3x15min per week) and honestly did notice the benefits, aiming at life quality when older. Which is sooner than you think. Getting something into your routine that you can actually make a routine has helped me at least. This post brought to you by procrastination between sets.
