Hi guys,

I am having some white-ish(theres a mix of white and black smoke) smoke coming out from my exhaust when i hit full boost. Read a few threads but all seems to point to the turbo seal.

The turbo on my car is a brand new HKS turbo hence i dont think it will be the turbo seal. No smoke of any kind when it is idling. Just on boost, you can see a cloud of smoke.

Any ideas what could be the problem?

Thanks inadvance!! :cool:

Aren't you supposed to do a break in before going full boost with your new turbo? Problem might not be with the turbo seals but the other oil seals in you engine. Since the new turbo would be pushing more pressure, those seals might have gotten worn out faster than expected.

White smoke when car is cold = evaporating water condesation

White smoke when accelerating = oil < from turbo, oil rings >

Blue smoke if what desiels blow normally,

Black smoke is octane. Either over fueling or not enough spark.

Is it making same power as before. If its just has a rich tune or lack of tune and is running rich it will blow black smoke = over fuel.

Thats fine.

I am having some problems with my tune. send it back twice and the engine light is still popping out on low boost 0.85 bar(10 psi?) Havent been driving on high boost.

This is the dyno graph and i reckon its a bit a rich side. Black residue all over my bumper and garage door. And also i did have lots of misfiring problems with even with new plugs and splitfires.

Turbo oil seals.

Otherwise, engine issues (rings, etc)

Daniel has alot of experience with this :banana: ey daniel lol.

normally id be going straight for the turbo seals but being a new turbo that makes it abit unlikly that the seals are failing already,but anythings possible right!?

if the smoke is a white/grey colour under boost then check your cooler and intake piping for blow-by, check your catch can (or get one if you don't have one) and do a wet and dry comp test on your motor checking for consistency and drop differences.

after this you will have an indication if the problem is your motor or your turbo.

    • Hey @Butters, did you end up getting this clutch in ? I have just ordered to a uniclutch track to go in my getrag 6 speed that’s in my BNR 32     
    • I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive
    • Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?
    • This came quicker than I thought. It ain't even 2025 yet.
    • I somehow quoted my post instead of editing it. I regret nothing.
