yeah no kiddin'. I heard a gross story about a guy that had a detroit diesel runaway, so he yanked the intake hose off and sat on the intake right before the turbo.......uh...that was the last thing he ever did. The moral of the story, NEVER sit on a turbo!

its is an AAZ, my hand is fine, wasnt driving long enough for the turbo to get hot.
it was reving at 5k for about a minit, it may hav been less, seemed like ages.
its amazingly easy to change the turbo on a mk1, only took 20 minits. ive been driving it since, it seems fine no damage at all.
although my replacment t3 is also spitting oil, if anyone knows about changing seals advice wud be greatly apreciated, and where can i buy them from?

it has nothing to do with getting too hot , but rather SUCKING all the flesh off of your hand into the engine ....
a couple posts up mention a guy with a detroit diesel ....... what i had heard with the story was he sat on the engine to stop it from running away , and it sucked all his insides out his butt and killed him .

Thats pretty graphic in words alone ... :x :shock:
With the minimal knowledge I have with turbo diesels...is the "whoosh" you're all mentioning have to do with the fact that the amount of boost is causing the turbo impeller to turn backwards after letting off the pedal? I know on a buddy's dad's duramax, they did a larger exhaust and chipped it and it makes a "whoosh" noise and this is what he believed what was happening.... :?:

the garretts totally rock over the kkk's
it has just a little more lag down low,but when it comes on
it hits in the middle harder,and carrys up top more
my tdi-m proved that for me
et's with kkk:14.4 or so
garrett,14.1's or so
my garrett blew the turbine wheel right out the downpipe too at the track once
i just disconnected the oil feed line and plugged it and drove home
track officials didnt find the wheel either...

sucked his insides out his butt? urban legend or what!!! time for myth busters! :lol: who is stupid enough to sit on an intake anyways? i guess if its all he could think of... i have heard of people getting their insides taken out by pools and living. just need to be on a machine for the rest of their lives.
as for the woosh its just turbo surge... the turbo is going from a super high rpm say 200'000 being fueled to not being fueled at all... so the engine requires less of the boost pressure, so some of it can't be sent through the engine... so it starts to come back out the inlet of the turbo. a BOV in this case would probably be a good idea. make it come on when the engine returns to idle and there is more than 20 psi boost hanging around

I'm wouldn't be so sure that is an urban legend. I've read lots of really messed up warnings in aircraft books and they have all been written in blood. :S

I've never heard of someone using a body part for it, but I know some old 2 stroke diesels have enough suction at the intake to eat a phone book.
mythbusters disproved the pool suction myth IIRC, but the intake on some diesels would be considerably more than a pool filter pump...
Do not attempt to stop motor with hands, face, or genitals! similar to a warning on a electric chainsaw.

omfg lucky for me that the turbo shaft had snapped in half, sounds like i would hav been dead if it hadnt. just the inlet suck alone was enough to realy hurt
my t3 is definatley leaking, if i take the pipe off it spits oil. not loads but enough to worry me.
this turbo may hav not been used for 5 years or so, do you think it may just need running in? im sure the oil retern isnt blocked.
am i ok to not use an intercooler? i heard that with bigger turbos its not so important because there is more air volume and it never gets that hot
sorry if this is a bit of a tangent but i have aquired a tubular manifold, was wondering if anyone has tried running to 2 k14s from 2 exhaust outlets each? wudnt that reduce lag and also allow higher boost? or am i talking ***? :roll:

actually rich,
somebody here on the forum built a dual turbo motor!
off the top of my head i can't remember who? but it was impressive!
somebody will chime in that knows where that thread is!

thats why i use a chunk of 2by4
those detroits rule
i saw one run away one time(detroit 12v71),the mechanic took a sledge and smashed the fuel lines right off the cyl head!!!!it quit within 3 or 4 seconds

you could always incorporate a butterfly valve hooked to a cable. I bet someone has to make a compact one.

i remember seeing it on TV and it showed the little boy who's innards were sucked out because he sat on the water suction port where the cover broke off. if you get a good enough seal the hydraulic effect would certainly put lots of pressure. now pools are required to have two drains so that you don't have that happening... they even measured the suction force and it was pretty high. only way to get the kid off was to turn off the pump.
i think mythbusters disproved a myth where the fire rescue helicopters sucked up some scooba diver with their water pumper... obviously that one failed because of the size of the opening and because you need the hydraulic effect from the water (putting a glass in water, filling it, and then raising it above the water level... the water doesn't drain out until you break the air tight seal)

I'll make another suggestion for people that wanna be fancy.
Carry a CO2 fire extinguisher, or make your own with a CO2 tank from a paint ball gun (some piping, and valve system that'll evacuate the whole bottle in a second or two.)
Gotta have air to burn on a run away, and it gets you further from the intake.
the CO2 will prevent fuel or oil from being burnt by lowering temperatures in the cylinders and displacing air.
