Turbos, new set and killed them.....

Guys, WTF is going on, I picked my car up on Monday night, after having a second hand pair of stocks put on, and withing 100 mile as I pulled into my estate luckily, death wine, louder than a fire claxon, jeez you really do know its a death wine when you hear it, and 0 boost, seems I have had a second failure. Turbos had done 70,000, but were pulling very stronge for a stock car and from a mechanics eye looked very clean.

 

Is there anything on the car that could be causing this ????

 

So say Im a little miffed, peeved, disapointed, and suicidle is an understatement, so far this year I have driven my car for about 3 weeks, and now that day seems even longer away. Still I had her for about 90mins, up to 1bar, and onto around 120mph, good while it lasted, still its like sex, thats that till next month :D

 

:conf: :conf: :conf:

 

If your going to ask did anything feel strange, or did this feel like this dont ask, anything to do with feeling was strangley over powered by the excitment of having her back and forgetting what she felt like anyway, just hadnt driven her enough to know....

 

So your views :confused:

Yeah Im feeeling that end of the stick at the moment...The car they came from when on was performing brilliantly, pulling very strong for a stock pair, and looked clean, so Im told.....as I said done 70,000, and was run at 1.2b for about the last year I think.....

They were my second hand turbos. I donated them to Ash when I got my Single upgrade. I'm really gutted for you mate. I never once had any problems with them. They ran 1.2 bar for the last 6 months with a couple 1.3 pulls. Always pulled like a freight train.

 

Up until November, the car has only had an induction kit and exhaust. So, the 70k miles on them couldnt have been that bad.

 

Really sorry to hear mate. :(

Why did you replace your turbo's? Did the no2 go on the original ones? If something went with the original's did you find out what it was that caused them to go?

Who did the install? It's VERY important to prime them with oil before you start the car up for the first time, otherwise your going in dry (so to speak ;) )

What were you using to know they were running 1.2 bar on your drive home? Bleed valve/boost controller?

 

I'm really sorry to hear what's happened to you. 3 weeks in 4 month's sucks, but I know you don't want to strap yet another pair of blowers on, for them to go again due to something like a VSV not working or some-such.

 

Regards

1) I think that these ceramic turbos are prone to failiure !!!!!!!

2) not only were they filled with oil pre shipping and on arrival but primed before start up

3)Restrictor ring

4) How can a VSV cause a turbo to fail ????

Especially after 70k, and with some 1.2/3bar burst. It was a gamble, that unfortunately did not pay off. :(

 

Nothing wrong with the car, hybrids/single would be a logical step if the budget allows.

So I take it you fitted them then Dude? Well at least that puts "fitting error""out of the question.

 

I know what your saying ala ceramic turbo's but two sets within a couple of hundred miles of each other seems a little unlikely, and I'm all sure we'd hate to see it three.

If the valve that opens to pre-spool no.2 fails and is shut, or only opens periodically, can't full blatt to no2 all at once, cause it to fail?

Gamble or not, its kinda odd or just dumb luck that it went after just bolting them on. Like I said, I have never had any issues with them whatsoever. 65 of those 70k miles have been virtually stock boost + exhaust.

 

I literally gave the turbos to Ashley as I knew his car had been off the road for some time. The only reason I got rid of them was to make way for more power in the form of my single. :)

Pre-spool is certainly kinder to no.2, but not having does not cause it to fail. Some people used to disengage it when fitting EBCs in the false belief of quicker spool.

Gutted for you Ash..........

It may be worth having the turbos fully inspected before strappin a new set on?

Could this possibly be oil starvation?.....even then if the new ones were primed ect it would make no difference in the end?

 

Just an idea?

Paul

 

Yes, UK ones are steel rather than ceramic. Ceramic blades don't like high boost pressures, and it is not uncommon for them to fail.

Perhaps wear wasn't the cause - if your injector(s) are fouled up and not delivering enough fuel, you'll run lean, your EGT's will rocket and your turbo will go pop.

 

Got an EGT gauge or a AFR gauge?

I asked the same question m8

 

But apparently the original turbo blow out emptied the sump in 20 miles - so cant be no oil getting through!

 

:(

 

Dont worry Ash - we'll get you back on the road somehow!

 

You can have the set of stage 3 hybrids at cost and pay me back on the never if you like - Dude will no doubt work something out with you too!

 

Get some decent injectors and a resistor pack off Emin and away you go!

 

Always look on the bright side of life de-dum..de-dum de-dum de-dum etc etc

 

:p :thumbs:

Ahhh...c'mon m8! You'll do my reputation no good at all!

 

When you get something like this happen it's a real bummer for the lad!

 

Even if he is a skinny git!

 

Normal service will be resumed later!

 

:p

ash - am truly gutted for you to have this happen. wrong things happening to the wrong people and all that ... :(

 

i've been in jason's several times and it did pull quite strongly and without problems (remember a certain night on the M1 J ?) so am surprised it fell apart so quickly. guess it must be dumb luck then.

 

all the best ash in whatever route you choose ... :)

 

paul - good on you mate for offering your help .... not many would i'm guessing.

IMO the most likely explanation is that the turbos had been dropped sometime on the way to me which could put them out of balance seeing as they spin at over 100,000 rpm , the box was pretty battered , the oil feed pipes are not blocked allthough for safety sake i think we will now replace them , i'll also be stripping both sets to see what has failed .
