View Full Version : No Boost and smoke!!!!
All,
I need some advice please...?? I got my car back from Dude on Thursday after having a FMIC amongst other things fitted. Anyway when driving I was not getting anything above 0.5bar boost and so I checked hoses as per Dude's advice and sure enough one had come off.
I've since replaced the hose and made sure it was secure. Went off down the road hit 1.2bar....:D Great I thought, however the next time I tried I had no boost at all (Won't go above 0)
I checked the hoses again but can't see any loose ones. All seem secure. :)
The worst thing is the car is smoking all the time once warm. Does not happen when cold but once warmed up I get big puffs of Blue smoke on lift off and when accelerating, even on tick over it smokes a bit. :eek:
So I wondering if my blowers have gone or what else it could be???
Any advice is greatly appreciated as I'm very concerned....:(

Have you taken it back to Dude?
That would be my first step if it worked OK prior to it going in, I'm sure he'll be happy to take a look over everything.
What "other things" did you have fitted at the same time?
It's not something as trivial as fuel cut as a result of mods is it?
oh dear mate,
Sounds like turbos to me.
:cry:
Sure its nothing simple like a huge boost leak with the newly fitted FMIC?

ditto
Cheers guys,
I've spoken to Dude a couple of times so I know what I'm looking for now. I'm gonna take out the drivers lamp to check the hidden clamps.
I was just a little spooked by all the smoke as well. Did not think the hose being off would cause smoke???
I just don't wanna have to drive all the way back to Dude cos it's like over 100 miles from where I'm staying at the mo.
Any luck Matt if not ive got to come up and meet Terry to pick something up i could swing by and take a look if you like , let me know and we can see what we can arange .
Dude:flame Dev
Bad news I'm afraid....:eek: I've had the drivers headlight out and the battery. All hoses are secure and have been re-tightened...
I can't even drive it really at the moment as it's smoking really badly. People were flashing me earlier after I took it out to check...:(
Really can't understand what's happened??? Everything else looks and seems fine...

you not done a piston in have you. i was in a mini convoy with mate in his skyline other mate in uk spec supra me in mine and a escort cossie and mr2. mate in skyline shoots off at high speed other mate in uk supra gives chase and going round a sharp bend at high speed a big cloud of white smoke starts coming out of supra, i thought he had blown a turbo but in the end it was a piston.
you you have many safety and cooling mods??

Not sure exactly what you mean mate?
I'm running a S-AFC to control fueling so that should be fine and a AVC-R to monitor and control boost.
Also got a restrictor ring to limit it to 1.2 bar.
Cooling was standard J-spec until the FMIC was put on...:thumbs:
The smoke coming out is deffinately Blue
Cheers.
:)
Matt give me a bell when you get up , what boost did you say you hit when you put the clips on ???, blue smoke is not good :eek:
Dude:flame Dev
Well it looks like my turbos have given up the good fight and I'm left with a 0 boost smoke machine....:(
I am finding that hard to believe, you said you boosted fine to 1.2 bar, then the second time you only had 0 bar.. didnt you feel the car being hesitant? or see a cloud of smoke the second time round when you got 0 bar? :conf:
I did not notice any smoke but there may have been. I was watching the boost gauge...:( I still live in hope but with all the smoke it does not sound good.:eek:

Bastard for you m8!:(
Tell me about it....:eek:
You have mail Paul...:)
Matt, what other work did you have along with FMIC. Blue smoke means your burning oils somewhere, and is most probably where you have blown your turbo seals. To be honest mate I wouldnt drive it until you have had it checked over as if your burning oil you could be in danger of using oil your oil and seizing your engine.
My turbos blew after going FMIC, and walbro/FSE, and I had blown turbo seals, which would have pretty much dumped all the oil within 30 miles.
Feel for ya man ;)
Is this a case of the turbo seals being a little worn anyway but still holding until specific flow enhancing mods are added and backpressure reduced thus causing them to open more than previously?
Whow knows mate, your now diving into the realms of serious mechanics.
What do you mean by "specific flow enhancing mods" ????
And "backpressure reduced" ???
Are you sayig this happens when say going FMIC or Walbro/FSE ????
I don't know if something like an FMIC will have the same effect but I suspect the turbos on my car were in need of replacement shortly after I bought it. At the time it has a standard exhaust with CATs and I got no smoke, no oil loss.
I added the NuR and decats which reduced the back pressure - apparently this then had the effect of failing to keep the turbo oil seals tight (CW helped diagnose this in an old thread - he suggested stuffing scouring pads up the exhaust to get the backpressure back and test for smoke).
Just wondering if the FMIC has helped to highlight the issue further?
mmmmmm, some good points dude, but your asking the wrong guy, anything about getting stoned ;) Im ya man, back pressure and stuff, who knows............
Hopefully someone will elaborate on this :innocent:
matt - i feel for you mate. as you know, i thought mine had recently gone too but it turned out not to be the turbos but something else (just exactly what is another question) ... :)

I know i'm an outsider of the supra world but this thought did cross my mind as a cause:
You said originally that a bad hose was causing you to only be able to make .5 bar,(now i'm assuming here it was a boost hose) because of this, i'm pretty sure that the turbos would be running 100% all of the time to try and make the desired boost (wastegate actuator would never recieve enough pressure to open the wastegate) so if you were throttling it hard, then the turbos would have been running way over the top, which caused seal failure.
Just an idea, i'm probably way out but it's worth a thought!
Charlie
The hose was probably one of the pipes from the pressure lines that controls the actuators which open up the valves to start the 2nd turbo spinning..

ahhh damn! i guess i suck :innocent:
Thanks for the replys guys...:) Nice to know people care.
I still don't know for deffinate what caused it or what exactly it is that went or even if one or both have gone. :confused:
All I do know is I have lots of smoke and so my turbos are going to be little more than paperweights soon......
:D I'm going Single :D
nice one! :thumbs: any idea how it will affect your insurance premium?

Matt could you clarify which hose you mean, was it an intercooler hose?
If so, the engine would have been sucking unfiltered air and whatever else it could hoover up. I'm wondering if some of that detritus made its way through the engine and then met the turbos. :bang:

I'm in Shenfield, litterely behind the high street.......
I've often seen another silver supra driving around along with a red one which lives on the main road and gets driven by a blonde..

Hose wasnt off just needed jubilees tightening up more , strangely a lot of the turbos now failing seem to be No1 !!!! Mind you seeing as Matt has an HKS filter he may as well not be running one !!!;)
