Blown Turbo On Ex Hpi R32 4door Rb24 Motor

[RBwhatever]

Ben Ellis isn't the editor for HPI anymore. Some new dude is doing it.

WOW

That's AWESOME!

I vote "Best Turbo Failure EVAH"

My vote is in! I have never seen anything like this one before? I was in so much shock when it happened!

Still am... Might pay Otomoto a visit to show them what happened!

[Swiper the Fox]

dont use KKR hose clamps either...

they are shit...

how do i know...

unfortunately i tried to use them...

[dori34]

get in contact with otomoto @ www.otomoto.com.au

im sure they can do something about this for you

the first ive heard of a KKR turbo failing but from others and what ive heard, theyre pretty good for their price.

[Guilt-Toy]

at the end of the day, to KKR's defence.. I would hate to know how many turbo's they have sold. If this is the first one to fail like this and it had a Bee R connected to it then damn KKR get one vote from me!

There is no such thing as a mass produced product that does not fail. I have used the KKR turbo before when doin up a r33 and i must admit for what they are they aint doing too bad.

This is one shock horror story, why is it everyone has to go and say KKR turbos are crap. Sure they are cheaper then the expensive ranges but one failure guys...

How many more people on this forum have had a KKR fail like this or even fail at all ?

[dori34]

^ thats true,

how many Garrett turbos blow & you guys knew about it?

alot

lol yeah the GT series have been accused of shitty/weak bearings BUT I really think this comes down to the owner. Not allowing oil temp to be at operating temp before giving it a hiding.

When water temp is at operating temp oil temp is still cold until ~7-10mins after water temp reaches operating temp.

Thats my experience anyway.

[Bass Junky]

I think all turbo manufacturers can have a lemon or two, and I know of a certain car that has had several Garretts blow after only hours of driving....

Having said that though, this failure is absolutely, completely and utterly catastrophic!

I find it hard to explain how that could have happened...

[Adriano]

Has anyone considered it may have injested a foreign object?

[Guilt-Toy]

why would they do that? its easier to blame the turbo for being crap.

I mean lets put heaps of fuel in the exaust manifold and fire it time after time causing massive backfires and explosions and wonder why the turbo explodes.

I dunno but i thought the cyl's is where the fuel and spark & bang should be, if you put a bee-r on your car who knows how big of a explosion you might be causing around the poor little turbo.

If you send them the bits and say please explain and tell them about the bee-r they will laugh at you and tell you to go jump.

Has anyone considered it may have injested a foreign object?

[Psymon]

Unless the bee-r was put on when HPI built it?

[RBwhatever]

Yeah I believe it was installed when HPI built the car.

So can we come to the conclusion: Bee-R Rev Limiter=Turbo Killer?

[GeeTR]

A thought... the truss’s or ribs on the back plate, although not thick, would provide some bracing, to think it snapped there is pretty wild.

Many people use the Bee-R device, plus many more the anti-lag function the Motecs and Autronics have (both cause ignition through the manifold / exhaust)

Instead of any amount of back firing through the exhaust causing the failure, maybe it was some sort of external force on the compressor cover due to excess engine movement, or something.

[Green_s13]

that is one nasty turbo failure, maybe the cheaper materials have caused the degree to which this has failed however the bee-r rev limiter would surley be the cause of thise over time. i personally have never used a kkr turbo but i have heard good things about them

i would be chucking the cooler in the bin or pumping alot of high pressure air though it for a few hours to blow everything out, also check the inlet and throttle body, hope the enigne is ok

[Beer Baron]

It looks like it shattered just due to poor quality material. but obviously something happened to trigger it. either wheel spinning out of balance, or foreign object, but the way it just fell appart is not very encouraging. yes I've seen plenty of garrets fail for various reasons but I've never seen one end up like that!

[abu]

That is pretty damn bad! Poor quality for sure.

I was just looking at thee KKR turbo's last night, well and truly put off for good now.

[RBwhatever]

Hmm yeah. I was contemplating buying a kkr430 for a mild upgrade if the stock one spits it.

Not so sure now.

Edit: Its still a valid option

Its common knowledge that bee-r limiters aren't great for turbos... but for one to cause that sort of failure? I dunno... i'm sure it had its part but i think there could have been more to it.

[Cubes]

A little bit of speculation.

Maybe it was dropped prior to install?

Caused a hairline fracture on the comp cover backing plate that eventually failed causing the comp wheel to fail the way it has?

How otherwise would the back plate fail in the way it did?

[BHDave]

Best failure ever!

I'm impressed.

I think the backing plate failed as the compressor has just disintergrated at 15k rpm and eaten the housing rather than throwing off the blades but leaving the center of the wheel intact on the shaft as usually happens when something is ingested. Thats a fair mass of material with a lot of energy to disipate.

In all honesty, shit happens. For a pretty cheap line of turbos there are surprisingly few failures that i've heard about. And despite my thoughts on the Otomoto/HPI link the guys associated with the mag and company all seem to run these turbos on their own cars which atleast shows some confidence in the product.
