Turbo Damage..?

[nissan200sx.dk]

Hi there.

A week ago I was to a car meeting... Gave it some ass in first, burning rubber, then drove forward, I should park, the engine died, fired it up right away. Died 5 - 10 secs after it was punched, and was started within 2 secs again.

Ran 20 psi boost.

Could my GT3076r turbo, with same size oil restrictor as from ATP, have taken any damage?

Also today, was driving slow, clutched in and engine stalled. released clutch within a second so fired ud again, could any damage have taken place?

I hope not... There isnt any smoke, or missounds or anything.

sounds like a problem somewhere else, maybe the AFM or cooler pipe leaking, and not with the turbouitself

[BAMR33]

Checked for any vacuum leaks?

Im experimenting with a new dump valve design Ive made, prob. thats why it died on my... But my concern is, any possible damage to my turbo.

[666DAN]

sounds like the dump valave is stuck open

Could be a tune issue, if using an aftermarket ecu.

If you started the car straight away, the turbo should be fine.

[MBS206]

wouldn't be a turbo issue.

It'll be something else. Do you have a atmo BOV?

Hmm.. But could there be any turbo damage??? That is my question, i know my valve have issues... Im experimenting with it... Making different types of pistons inside, different clearances and so on.

The only thing im concerned with is turbo damage because of no oil pressure when engine died, in those two situations as described in my first post..

Its not ideal, but i doubt the turbo has sustained any real damage

[nissan200sx.dk]

Know its not ideal... But it need very little oil to get lubricated.. Hole in oil restrictor is only 0.85mm, as per ATP turbo, oil in to my turbo is faily high.

I mean, it has around 8cm different fittings straight up from, oil in, on turbo. Both to clear the housing, and to get from one size thread to the steel braided hose I use.

So in that 8cm pipe, from turbo oil inlet straight up, 90 bend and then my steel braided hose, there will be oil still lubricating the turbo when engine is turned of.. There is about 30 ml oil in the pipe, it cant run back to engine, only way is through turbo... So im trying to calm myself saying there is no damage to turbo, has just replaced the turbo, blew the old one with too much oil pressuere, and is under education, so dont have money. hehe. So basicly I want to be calm'ed.

Good son of rajab, i thought my swedish/english was bad...

What ever your trying to say, i doubt your $2000 GT3076r has taken damage. It would be a "sensory input to your ECU" issue me thinks. Check that nizzle out. You haven't told us bout the basics, so widdle the branch and let us know

[nissan200sx.dk]

hehe.

What is it you dont understand of my english?

Its straight forward.....

What "basics" do you want to know?

[daisu]

Just because your engine was off few a few seconds I don't think the turbo would've suffered any damage. I'd say damage would occur after heavy use (like the skid you pulled) then turning off and leaving the car turned off for extended period. It would be more from when the turbo has stopped spinning and it becomes unevenly heated without the oil to help disperse the heat. It's not going to stop spinning after a couple seconds of engine off though.

I dont think so either...

Just wanted to be sure. hehe.

Would really hate myself if I buggered the turbo because engine stalled.

[Aif]

So basicly I want to be calm'ed.

there there little buddy, everything is going to be fine *pat on the back* you know when ever i think something its wrong with my car i put on my happy shoes and dance like Napoleon Dynomight. and if that doesnt do it for you, then u might take comfort in the previous posts have all said things like "I don't think the turbo would've suffered any damage" "i doubt your $2000 GT3076r has taken damage" "i doubt the turbo has sustained any real damage" and "wouldn't be a turbo issue"?

do you feel better? *hugs*

AiF

P.S. it feels a little to me like you want someone to say your turbo is shagged.

[s13_Skyline_inside]

your turbo would be fine, as said before its if you let it sit still for a decent periode of time after it's been totally thrashed so it has some decent heat in it.

[nissan200sx.dk]

hehe.

That helped alot. Needed to be calmed... I get really nerveus about my car.

Trust me, I dont want to hear its buggered.. Skipped my summer vacation to afford this turbo... So no no no, dont want it to be shagged, buggered, busted, damaged or anything. I'm under education, so dont have alot of money....

Want it to be in super mint condition.

.....

I wish for a money tree for christmas.

lol I love half english speaking people.

The words they use crack me up.

Won't be a turbo problem dude - sounds like a sensor issue. Will be easily sorted.

[TTT]

LMAO at the number of people trying sort out the stalling issue.

ALL he wanted to know was.

Will the car being off for 2 seconds before being turned back on, cause any damage to the turbo since he had just done a lebo wedding move.

he knows the stalling issue is his "experimental" atmo venting bov.

he was asking if the turbo could be damaged by the 2 seconds the car was off immediately after a burnout.

at least some people go that.

[The Mafia]

ahh I see

nah, 2 seconds won't worry it at all.

I wouldn't let it go for any longer though
