Did I Blow My Turbo Up...

[wizlb]

I was cross the Harbor bridge head toward Castle Hill and this sound >>> boom came from my engine. I was about to get off the hwy.

The engine sounds fine when I am reving,,,,but my boost level is around 17 KPI, if KPI is correct.

Can someone tell me if I blow my turbo and is there anyway to tell from looking at your TURBO if it is blown.

One last thing, when I open my hood the turbo look like it was on fire...the color red!!

Thank for your help !!!!

do you mean KPA? 17 KPA isnt much - ie; its shagged

the best way to check is to drop the exhaust at the dump pipe and inspect the exhaust wheel

usually it fails and the turbo looses backpressure, thus the compressor does nothing - ie; no boost

you could also try undoing the bolts to the CAT and look for smashed bits of ceramic - the wheel can often end up there

[wizlb]

Thank Paul.

Should the turbo be red from heat.

[wizlb]

One thing is for sure.

I am not able to fit my car. But if someone can tell me other ways to see if it is blown, so very cool.

[paulr33]

glowing red indicates excessive heat, heat usually makes the exhaust wheel fail / crumble apart

[wizlb]

I silly question but where is the exhaust wheel located behind the turbo?

Thanks for your help Paul. Do you know what will cause this problem

[cuppas]

your best bet is probably to get a mate whos good with cars to have a look over yours

dead turbo wheel? possibly too much boost/poor tuning

possibly not a good idea to drive it until you know what exactly is wrong with it

I forgot to mention this, I just had a shop install Camshaft and a retune.

Here is the dyno run and can someone tell what they think of the tune.

What sort of turbo? std or hiflow? HKS? etc etc

Dyno looks fine, but really doesn't tell us anything. Need the boost level and the AFR graphs.

It is a hi-flow GTT34 VG30 back

I will get the dyno sheet tomorrow.

No blown turbo just some damn leakage.

[neo32]

so the sound was a cooler pipe blowing off?

How fast were you going across the harbour bridge then?

As a club, we don't condone speeding...

[tridentt150v]

Ok, why would the turbo glow red if it wasn't working [and assuming he was just cruising [not flogging the bejesuz out of it] before it happened]>>>our was he???

[wizlb]

How did you get to speeding from what I wrote. Lets stay focus here. One of the pipe connecting to my intercooler came off and this had little or if anything to do with speeding.

I really would like to thank the people who try to help me.

[DRD-00F]

A glowing turbo, and blowing an intercooler pipe off so it makes a BANG noise doesn't happen while you're parking.

[Munkyb0y]

does it really matter? he found his problem.

and whats wrong with parking at 7k rpm ?????

[DRD-00F]

No it doesn't really matter. But he asked a question so i replied

Parking like that is ok... but you better be sideways!

[wizlb]

I am not a great writer and that may be the reason there is a little confusion about what happen.

I was on the hwy and the intercooler pipe came off and it created this sound>>>boom<<<

I was able to get off the hwy and park the car.

Thanks for you help.
