    Golf R Turbo Failures

    Golf R Turbo Failures Hello all, long time no post, lots going on here, tuning development etc etc. I have tuned over 80 Golf R's, and of those cars 4 have had turbo failures. That's 1 in 20, which is not a good stat. I have also had a number of customers that have booked their car in have to cancel, due to to the turbo failing on completely standard tune. The last of these failures occurred earlier this week while on my dyno. This was frustrating but as I was logging at the time it allowed me to study first hand. The car had done one flawless power run, and then failed on the second. Data logs showed everything was perfect, with boost at 1.5 bar at the time of failure. This is less boost than virtually every tune available for the Golf R runs. So what's happening? Obviously I was keen to find out. The IS38 turbo borrows technology from Motorsport and employs a "zero clearance" compressor design. There is (virtually) no clearance between the compressor wheel and housing. This improves efficiency and contributes to the incredible performance of the turbo. The compressor housing is lined with a Teflon insert, as the compressor wheel will come into contact with it in normal operation. The issue is that batches of the turbo have not been balanced properly. A number of turbos have now been stripped and examined, only to find the balancing is out by a very large margin on a number of turbos. This causes the compressor wheel to move off centre slightly. On a "normal" turbo this wouldn't be an issue, but on the IS38 the compressor wheel is hitting the Teflon insert, digging in - and snapping the shaft instantly. In other cases, it is undoing the the retaining nut and then causing even more of a mess. The shaft diameter is considerable - it's a very strong shaft but when it suddenly goes form 100,000 Rpm to zero something is going to give. Early 2014 cars have had the most failures, but the failures are not isolated to these. We have seen failures on 16 and 66 plate cars as well. No failures yet seen on 15 plate cars, including mine which had run well over 2 bar during development. The IS20 found in the Golf GTI turbo does not suffer from this issue, it also has a much smaller/weaker shaft diameter but is properly balanced. We are now recommending that anyone tuning their Golf R has the turbo checked over for balance. Pricing is not expensive - around £250 - but there is obviously the labour involved in removing the turbo, and the 3-4 days the car would have to be off the road. The compressor insert is checked and re profiled to correct clearances, and then the rotating assembly placed on a VSR balancer to check and be adjusted as required. Options to hybrid the turbo will also soon be available but these are not required for Stage1/2 tunes. This is not any kind of ploy to extract money out of anyone, but born out of the frustration of trying to tune an incredible platform with a major weakness. Anyone is free to send their turbo to any specialist turbo company that can perform a proper balancing operation. Thanks, Rick

    My 7.5

    Aren't you the guy that was giving everyone a hard time on the embarrassed thread saying you didn't own one and challenging owners to race your mighty M140i if we were in your area? If I remember correctly, you were calling the R 206BHP of S#IT. If Golf R's are crap and loose a ton of money, why did you buy one? Actually, you first said you had picked up a new WRX STI in October '15 then changed it to a mighty M135i in April '16 then in a later post corrected it to M140i in February '17... At 36 posts, looking through your post history it's just a stream of abuse towards Golf R's, owners and how they're financed. Is this even your R or are you just trolling us even more?

    I'm going to bill every one of you!

    Before I subscribed to this forum while researching my impending R purchase, I didn't even know what detailing WAS! Now I find myself with a Kamikaze Enrei coated car, snow foam and lance, wash mitts, buckets with grit guards, pH neutral shampoo and goodness only knows what else! And you're all to blame! So you can all contribute, please! Car was covered in some sort of sand, so snow foamed, washed and quick detailed this evening. The Kamikaze coat really is amazing... I love it! In all seriousness, thank you all for such an informative, friendly forum. Sent from my iPhone using Tapatalk Pro

    My R now with GTi Clubsport S discs Just had my my R fitted with some GTi Clubsport S front discs and got my calipers painted blue. Wanted to introduce another colour and decided to go with blue to tie in with the blue lighting inside the car. Also have 12.5mm front and 15mm rear spacers.

Spec is: White Silver Black Pretoria's DCC There will be a few more additions as time and money allows. I also own a mk5 golf GTi which has its fair share of mods too. Thanks for reading Craig

    Wheel Storage

    So today I decided to buy and install some brackets to hang my spare set of wheels, while their not in use. I was going to use some industrial heavy duty Unistrut brackets, but I didn't quite have enough lengths of Unistrut to complete. I allocated a suitable space on one of my garage walls and I'm quite impressed with how tidy it's turned out. First it was a case of working out the clearances required. Fitted the first bracket and then checked the clearances again before drilling and securing the rest of the brackets. Decided to use pipe lagging as protection. I was going to hang the wheels with the front of the wheel facing out into the garage but the centre of gravity of the wheel swung the rim out further. Thankfully the rim protectors on the tyres are enough to prevent contact with the wall and additionally I've used bubble wrap as an extra protection. The end result is a nice tidy solution and I've used the fabric covers from ABT to help keep them covered.

    Did the final bits today… A second coat of Swissvax Best of Show, Sonax Brilliant Shine Detailer on passenger front wing (just for Gary - Mainframe, lol). Protection complete! Lastly, applied Aerospace 303 on window rubbers to freshen them up, tailpipes polished with Mothers and tyres dressed with Achem Hi-Shine. All done! Final details… Bit of trim attention Buffing off final coat of wax Then it was time to pack up the detailing tent and brave the elements once again. The tent has been fantastic for the spring detail over 3-4 days. It has rained twice during that time, not to mention tons of pollen blowing about, but car was kept out of harms way. If I hadn’t used the tent I would have had to do several additional washes to get rid of overnight debris. It was a bit of a weird purchase but so glad I did. Packing up Goodbye marquee! And took some pic home and away…. Reflection shots Some DBP flake in the sunshine And now I'm having a lie down and rubbing copious quantities of hand cream into my stricken hands!

    Just time for a quick wash today. I tried out the Race Glaze water filter, @#!king fantastic. Despite starting later in the day, when the sun was up full, not one single water spot mark. Well worth the cash. My water turns out to be only 225 ppm according to the TDS meter, which i think means i should get about 800 liters out of the resin.

    Leaving the R Fold for another type of R ;)

    Leaving the R Fold Morning all. As some of you maybe aware I've ordered a gtd as a daily driver meaning that the R just isn't as special enough to keep as a weekend car anymore so the R has gone But I've replaced it with this, delivered yesterday . Mainly to avoid the £2k ludicrous road tax. The V10 is something else and can't wait to test it out on the auto bahn in the summer. I'll still be active on here though having a gtd. More pics to follow once I've fully detailed it.

    So here's a before and after in mine Sounds is definitely more throaty and much deeper. When idling you don't notice it all but on the throttle the volume is awesome. There's a lot more noise in the cabin. On the motorway I thought I might need to set the flaps back to auto rather than permanently open as it is quite loud but now I just turn the radio off and enjoy the new exhaust soundtrack instead! Here is a before snapshot of noise from the cabin on the motorway: And here is after: I was quite shocked at the difference and wondered if it might have been too loud at first, but it's great and I love it! No regrets at all.

    Today I'm in a 7.5 R demo car

    So my good mate Chris at warrington VW has sorted me a day in a 7.5 facelift R, the car is a 5 door manual in indium grey, with a few options including pro nav, carbon leather, Spielberg wheels etc etc just thought people may like to see some pictures of the changes I've found on the car from the Mk7, i remember someone asked the other other day about the brakes & if they were the same or different, they are exactly the same front & rears on uk cars, some of Europe gets the option of clubsport brakes which are drilled front discs with different front & rear pads if if anyone wants any more info on it, let me know 👍🏼
