Yeah, but its like what came first.

The Chicken or the Egg. :)

In this case, the middle-area of damage to the wheel would suggest it came first, and the rest of the failure came as a resulting factor... being the middle doesnt "damage itself". Its almost impossible id imagine

I think this is a rubbish opinion, and you are seeing things, no offence.

There is absolutely no damage that hasnt been caused by parts of the comp wheel as it has disintergrated. Hell i wouldnt be surprised if the wheel itself was made from low quality materials contributing to the ease in which it came apart and then the damage it caused.

The core or middle as referred will crumble once oil seal has gone small washer/ring washer 2-3mm thick then bearing or bearings will crack and the core crumbles, shaft snaps, wheels go good buy and the retaining nuts fly off, leaving the housings shredded unuseable. Ill find my phone leed and post pics tomorrow

You cant rule out something coming causing problems but anything small enough to get in wouldnt cause a problem 99% of the time its balancing. Freak problems happen but still comes down to affecting balancing.

The only way you will know is if you take off the exhaust housings/compressor housings 6 x 10/12mm bolts and have a look.

Looking at the outside wheels doesnt tell you much we are all just guessing and you still cant be for certain lol thats about all i really know

because highflows get hotter as they spin faster so ive been told there not designed to run highboost but you shouldve still made more power, heaps of factors oil supply to bearings, quality of oil, oil temp,fuel quality/octane levels, fuel supply, air temp , afm ratings, temp on day between tunes at 14/16psi if done on same day could go did you watch it on the dyno i dont believe in tuning cars on dyno how may 7sec drag cars get dyno tuned NONE? Who Tuned Your Car? Lol

My mate owns racers Choice in seven hills he has drag cars/Drag Bikes/ Shit everything lol Lucky bastard not one of his cars ever gets dyno'd were goin off question here lol

Cheez i think you meant seeze lol

You still need a turbo

I have just read through this thread with interest. My Slide highflow done the exact same thing 6 months ago. Exactly the same situation, turbo was pretty new, had done approx 1500kms, had a proper, full power fc dynotune with z32, injectors, fmic, full exhaust, cams everything on 16psi and about 300kms later, one night it just let go. Boosted up then pop, no boost and grinding noises. I babied it home and pulled everyting apart and the pics are below. Nothing had been pulled apart prior so if there was something in there it would have been sucked through already. And it had a full filter setup so absolutely nothing could of or did go through it.

Yet when I tried to get it fixed under warranty, the owner Sheldon (because Aaron was uncontactable for prolonged periods) who builds the turbos said something must have gone through it or it overboosted. My car has the power fc boost control kit and was only running 1.1 bar and did not overboost nor did anything go through it. After being promised it would be repaired asap and within days it took weeks and they would not return my calls. After I finally drove down to see them face to face again I ended up paying for the new compressor wheel because they would not give me my turbo back until this happened. I was not happy. I have read many happy stories of people with these highflows but I personally will not be buying one again.

Here are the pics. That is just my story. Cheers

you're all blaming the idea of "something has gone through it"

where the hell is it then? The engine is ok, so why didn't it go through the engine and kill it too.

So forget the idea of something going throught.

They are probably stress breaks - the blade that hits the side of the housing gets force all the way back to the center of the wheel busting it in various places. And any bits that would have broken off would have bounced around and entered the compressor in any spot not just get "sucked in". The momentum would have been more than the vacuum and bounced around for a split second.

There is no way something big enough could have gotten through an air filter and done that. The air filter would be busted, the engine would be dead, etc.

i got this funy thought that they wont honour the warranty for some weird reason. cause i spoke to them today and he didnt seem genuinley intersted when i said someone has had a look at it and mentioned its under watrranty. they looked at it unopened ofcourse

I am no expert like the rest of you obviously,

but to me it would seem that the comp wheel has hit the housing and managed to break off one of the fins,

which having nowhere to go initially would have been bouncing around on the front of the wheel for a microsec or so under suction

on spindown and caused the slight damage on the high points of the comp wheel fins that remained!

I would be interested to know exactly where that offending piece of broken fin is now?

The problem is further back in the CHRA.

so much ppl having problems with slide high flow turbos,

read so many negative feedback about them so i guess its a good thing theyve stopped making them or else more issues will arise.

do the turbos come with warranty from slide?

Hey guys

The turbo's all came with a manufacturer warranty which is still based with the shop on the Gold Coast where we would help make and sell them from.

We have had around 7 highflows fail out of 1376 made.

Warranty is based with Murnane Motors in Burleigh Heads on the Gold Coast.

There is no longer an involvement by Sliding Performance with highflows due to the simple fact that the man hours requried to turn over that many turbo's even with a 3 week delay was atrocious and all involved decided that family and in one case health was more important.

The engineer would look at this turbo/pull it down and find what the cause of its demise was and will let you know.

:P Jase

Is it possible to see a damaged turbo with the compressor housing removed ? Only problem is that the manufacturer may void any warranty if it is .

From the pics so far the compressors look like 8/16 blade T04B wheels and they use fairly thick section blades . I mention this because if the wheel had a big rub and lost parts of its blades they could smash around in the snout of the housing bouncing off the leading edges of the blades .

If you look at some 8/16 blade T04B wheels the vanes are pretty close together and the exducer tip hight not high like later GT series compressors . What this means is that the escape route for bits of shrapnell is not an easy one so the high speed trips around the inside of the housing could last a bit longer and do more damage .

Many different things can cause a compressor to hit its housing , that GT3082R that R33 Racer sent me looks like it had an oil starvation issue long enough for the turbine end bearing to sieze up and friction weld its collar to the turbine shaft . I reckon the sudden violent decelleration made the shaft whip enough out of alignment to send the compressor blades into their housing . When I pulled it down the shaft was bent like a bannana .

Very high shaft speeds and end thrust loadings are not kind to bush bearings and thrust collars/plates . Super duty use is more likely to be long term reliable with annular contact ball bearings .

I have no idea why those turbos failed but the answer possibly lies with either their bearing system or the shaft loadings at high revs/boost (the turbo that is) .

So as not to be O/T I'm starting new thread for those with experience of Garretts real GT3071R on RB25DET's .

Cheers A .

ok the turbo is now off the car. ive taken pics of the rear wheel. as you can see its still in tact. i turned the shaft and both wheels still turn. still pretty smooth but wobbly. and dont look like nothin went through it...

Well I had better add my story then....

Yesterday at the track my Slide turbo did exactly the same thing. Wouldnt have even done 5,000kms. The car was recently tuned and we had 2 boost guages hooked up, no signs of overboosting. Exiting a corner in 3rd gear then BANG! no positive pressure. Upon inspection the comp wheel blades have actually bent outwards towards the front of the car. Nothing could have gone through the turbo and there is absolutely no end float.

Going to take some pics and send them off with a please explain and see what happens!!

:glare:

    • My goals for it atm are to get it registered, respray and some mild power gains eventually... I picked up the car from an elderly gentleman near the border of NSW and VIC, its honestly a bit rough and looks like its been driven on a farm (because there was so much dirt underneath). Last week I dropped the subframe and emptied the old fuel out + added a new fuel pump (think the old one went bad from old fuel). Now I'm onto fixing a coolant leak at the rear of the engine + adding a new radiator as the old one is corroded. After that i have a new bumper, coils (as the old were leaking) and lots more
    • Welcome buddy! Plenty on here and YouTube. What are your plans for it? Good luck with the Rwc and Rego bud!
    • Love this so much! Please post a photo when you have a bike on the trailer.  I was a little bit worried about having a tow bar on the Skyline, but having it hidden behind the number plate is genius
    • Came here to say, put all the wiring from the new motor and gearbox in that you can, then throw the stock ECUs in the bin, and get an aftermarket ECU. Should be pretty easy if you can use a multimeter and read a wiring diagram to then use a PNP aftermarket ECU to suit the motors wiring loom, and make the minimal changes you will to get it to work in with the body loom (If any). This will mean you can very easily circumvent/bypass the Park/Neutral start disable switch, and get everything running really easy!
    • If the roof is dual skinned the whole way, IE, there's a "top" metal piece, and a "bottom" metal piece, to slow it down as much as you practically can, you should be able to get an attachment for a spray can/your spray gun, where it is a long, thin flexible hose, and when you're "spraying" it is spraying it in every direction possible. The I'd get that, and feed it through the roof as much and as far as you can. It's basically like fish oiling the car, but you're soaking it in rust converter. Then do the fix like Murray has described having cleaned up the existing metal as much as you humanly can. I'd also throw as much rust converter on that exposed metal before putting the fibreglass/metal filler over everything.   As for welding a replacement in. I've owned my own MIG welder for about 10 years. I've also worked in an industry doing MIG welding for a job for about 3 months dead straight, and we were doing 11.5 hour work days 5 days a week, plus a Saturday 6 hour day. (I then moved over to running the massive CNC plasma as I could understand the technology, and work with the main guy out there). I also f**k around with my welders a bit at home. So what I'm saying here is, I've probably got more hours on a MIG gun than you'll manage to get under your sleeve doing home sorts of jobs over the next 5 years. I also have an ACDC TIG that I got myself a year or two back. I've got a short amount of experience on the TIG only. My home MIG is also presently setup for doing thin sheet metal. Unless I didn't care about how that roof looked, and I just wanted a functional metal roof, and it being out of alignment, warped, and bowed, I would NOT attempt a roof replacement UNLESS I could do it as a whole panel like Murray described where the spot welds were.  Welding has this REALLY annoying thing, where if you want something to be perfectly square, unless you can clamp that thing to damn perfection (Welding fixture table), it is NOT going to be square, so you start to learn, the type of metal you're working with, how thick it is etc, and weld in VERY specific ways, and by knowing how YOU are as a welder, so that as the welds cool, the metal work pulls itself into place. If you want to see some cool tricky shit done, Bennets Customs is an Aussie guy, and he mentions a guy a lot call "Kyle", who is from "Make It Kustom". Watch some of their welding videos, especially on sheet metal. You can use the welder to shrink the steel in, and you can also use the welder to stretch the panel out. When you have the skill level that I have, you can shrink the metal in and out... But never on purpose like those two guys do. You just manage to f**k it all up. Then I smack it around with a hammer till it sits lower than I will want it too, then I shove filler on top and then pray to deitys that I can sand it into some form of sane shape that doesn't look like a dog has taken a shit, after eating a tonne of pumice stone... I'm all for DIY, and for learning, and please, feel free to give it a go, but be aware, you need to live with the consequences of how time consuming it is to do, AND that it's going to look no where near as good as what you can make it look with just some filler now. Oh AND, even once you replace it, it's like to still rust away again eventually, because you'll have missed putting primer and paint on some part of the newly welded in sheet metal, or against part of the existing metal you couldn't get to...   Oh, and to weld all that in, you will need to pull the window out, and strip at least the roof and A Pillars of interior trim and wiring. You'll then need things like the big fire proof/weld spatter proof mats to lay down, OR you'll end up needing to strip the ENTIRE interior to avoid sending it all up in a ball of flames. If you want to see how annoying sheet metal is to weld, head to bunnings, buy there 600x600 1.6mm mild steel (Not GAL!) sheet, and cut a few pieces, and try and weld them together. Then understand, 1.6mm sheet is nearly 50 to 100% THICKER than the cars sheet metal.   The photos I posted before, I'm replacing with 1.2mm thick mild sheet, and it's very easy to blow through both the original steel (Especially if I hit an area that should have probably been cut out a bit more) or straight through the new sheet metal. And I'm doing the floor, which can be hidden easily, and doesn't matter how pretty I make it, as long as it's damn strong! I'm also doing it in a 4WD, that has seen many off road trails, and doesn't need to look that pretty ever
