The statement you made about the bearing clearances being off and causing smoking issues is also inaccurate and not even possible as that would be related to a defective piston ring on the turbine shaft or flinger. It's also not possible for our turbos to become elliptic as a result of bearing failure as our bearing carrier design would prevent that from occurring. Our engineering department has been in direct contact with Roger, the owner of Trollspeed, regarding a minor smoking issue under deceleration which was not a result of any turbo failure or clearance issue at all. As a matter of fact we have numerous emails from Roger stating how well the turbos were performing even with the minor smoking issue.

After our engineering department spoke with Roger they were able to deduce that the cause of the smoking during deceleration was a result of a thinner oil grade they were running. This is not uncommon with ball bearing cartridges as they require much less oil flow as compared to journal bearing turbos which is why all of our cartridges come with restrictors. In Roger's case all that needed to be done was for us to send him the next size down oil restictor and his problem was resolved. Roger even emailed us after the new restrictors were installed and stated how happy he was with the performance and that the smoking issue was now 100% rectified.

As we are in direct contact with all of our customers and vendors let us be very clear, we HAVE NOT had any documented or reported turbo failures from any of our KRAS55Bi customers. While we appreciate the input you're trying to offer to the community, we ask that you please provide proof when making such bold claims as to our turbos failing and needing to be sent back for rebuilds due to clearance issues. In this case there is no proof to provide that backs your claim as no turbos were ever shipped back to us from Trollspeed and no rebuild was ever performed. We pride ourselves in our engineering and product quality/durability which is why we take claims such as these very seriously.

Hi again. Sorry for late reply. I'm a good friend of Roger and know the guys at Trollspeed. I don't think that you got all the information from Roger about the turbos. Maybe he didn't want to bother you with it as it's a long way and also takes time to send them back, get them fixed and then return them back to Sweden again. First of all i want to say that the car runs perfect now and the turbos are working very well with great spoolup so Roger is very satisfyed with the setup so far, so all credit to you for that. The turbos were never sent back to you because they were sent to a turbo shop here in Sweden named SL turbo.
They rebuilded the turbos and rebalanced them. The car was also run on 10W/60 oil on the dyno so not thin oil was used.
As i said earlier, Everything can happen and noone is perfect. I do NOT want to throw any crap on you, the turbos and the design and performance is very good for the tune that Roger runs now, 668 hp at 2 bar of boost on a stock engine.

In the name of transparency, we've decided to bring to everyone's attention the root of why and how these false turbo failure warranty claims transpired.

A member of the bimmerpost community contacted us several months ago to inquire about becoming a Global Motoring Group Dealer to purchase our KRAS55Bi's for their company car. The name of the company this board member claimed he was affiliated with was Prestige Car Services in Abu Dhabi, which anyone is more than welcome to google and see is a very well established exotic car dealership that also does performance work. He was emailed a dealer application which he filled out and sent back for review. After reviewing the application management decided to approve it and offer our KRATOS KRAS55Bi's at a specified dealer discounted rate. During the last several months this individual had our sales staff write up numerous very high dollar quotes of which one quote he stated he wired the money and then changed his mind and canceled the wire after it was already sent, which we found odd. He would contact us several times a week to ask tech question about tuning and various other performance related topics. We also referred him to Halim at HCP tuning for his BM3 tune, which we were told he tried nickle and diming HCP and asked to pay less than half price. Then one weekend he tried contacting our offices over 50 times by phone, sent numerous emails and messages through our various social media platforms, and even going as far as to contact Halim at HCP on his whatsapp account on a Sunday to try to get in touch with us. All this to ask a tech question that he was too impatient and desperate to wait until Monday morning to have answered. Not only was his behavior extremely unprofessional, but also very immature and childish in the manner in which he conducted himself.

All this behavior got us thinking that there is definitely something not right about who this guy claims he is. What well established company like Prestige Auto Services would conduct themselves in such an inappropriate and unprofessional manner and then nickle and dime the tuner for such a small dollar amount compared to the type of day to day transactions this business conducts? Our management then decided it was time to speak to someone in charge at Prestige Auto Services rather than the normal contact name we were given on the application. At that point, it didn't take very long to figure out that the account was opened fraudulently. It turns out this individual was nothing more than a customer of Prestige Auto Services that fraudulently filled out our dealer application with a fake UAE Tax ID # and forged documentation to claim he was someone he was not. What he did is not only commit fraud, but also identity theft which is a criminal act. All this just to get a discount on his turbos.

This individual was then contacted and confronted about his actions, which of course he denied. He then changed his story from, "I'm an authorized employee and purchaser" to "I work for the company" to "I'm a customer and was given authorization by management" to finally when being told we would proceed with legal and criminal action against him "I'm a customer and shouldn't have lied to you". He was then told his fraudulent dealer account would be revoked as well as his warranty and was told never to contact us in any way, shape, or form again. He was also warned not to attempt to commit slander or libel about our company as a form of retaliation, as this would result in legal action. As many of you now know, this didn't stop him as he started creating false rumors about friend's of his having warranty claims as a result of failures on bimmerpost to cast doubt for potential buyers of our turbo systems. Once we realized his screen name on bimmerpost was M3anpower, we contacted Jason and explained to him exactly who this guy was and how he defrauded our company. Jason then took it upon himself to not only delete his posts, but also ban his account. This also did not stop him as he created another account M3mantis on the same exact day he got banned. He again continued on the same path making false claims that he had friends with failures. Whenever we responded and asked for names of these so called friends with failures, he would disappear or claim we were being defensive and never provide any proof. We then asked Jason if he could look into this account and confirm if it was from the same IP address, which he confirmed indeed was. Jason then took it upon himself to not only delete all of the posts M3mantis created, but also our posts that rebutted his defamatory information. In addition, he banned the account and the IP address.

So, making innuendos that we are being trigger happy and deleting posts couldn't be further from the truth. Maybe the behavior of deleting posts is what board members such as yourself are accustom to seeing from certain vendors. We implore board members to continue making screen shots of posts we've written in name of "integrity" as we have nothing to hide. As stated many times, we have always conducted ourselves in a very transparent manner and will continue to do so. Hopefully, this information provided will put any doubts or concerns regarding these false claims and accusations to rest.

There was never any doubt in my mind, and I don't think you guys even owe anyone an explanation, but this is what separates the great vendors from the mediocre/bad ones...

It's too easy for people to spread rumors/hearsay behind the comforts of their computer screen and keyboard nowadays. Managing one or two bad apples is not an issue, the problem is with the sheep that follows the herd. Haters love spreading false information out of pure boredom, poor use of judgement, or inability to properly process written information.

While I'm glad to have you guys as a vendor on this platform, I feel bad that you all have to deal with non-sense. At least I can say the S55 community isn't as toxic as the N54/N55, at least not at this point in time.

Johnny,

We have just spoken to Roger, from Trollspeed, the owners of these turbos to confirm that there have not been any new developments in what appears to now be an ongoing story. Roger confirmed with us that he never experienced turbo failures with his KRAS55Bi’s and that the information we provided in the previous posts regarding this set of turbos is the most accurate, complete and current. No new information has appeared since our addressing it.

Your explanation that Roger could not have been bothered to send the turbos back to us does not hold true as we were in constant contact with him during the process of providing him the increased restriction to his oil feeds. Further, as stated in our warranty policy as an action that revokes the 2 year warranty, the turbos were taken apart without the approval of our customer service and engineering representatives. Turbo services are only authorized to be performed in-house should the customer wish to retain their warranty. Pre-emptive to his contact with us, Roger’s third party mechanic contracted SL Turbo to diagnose his turbos as he believed a larger issue may have been causing his smoking. Upon inspection, no such issue was found. Roger contacted us after he had already had the turbos taken apart by who we now know to be SL Turbo. The transit times you mentioned are a moot point as we offered to provide a DHL shipping label should he have chosen to have the turbos checked over, which Roger and our sales staff knew to be two days of transit time.

In your prior message you stated that the bearing clearances were out of spec and this is the reason for the failure. If you claim any bearing clearances were off, it would not have been impossible for SL Turbo to replace said bearings and rebalance the turbos as we utilize a propriety ceramic ball bearing size and design that is only available through us directly. This statement that bearing clearances were off is simply not true in any degree. Should this have been the case as you stated, there is no possibility that the turbos could have been rebuilt and rebalanced. In addition, there would have been signs of damage to the compressor and turbine wheels from contact with the manifolds and compressor covers. This is clearly absent from the pictures you provided.

We have gotten all of the information from Roger directly. We have been in constant contact with him; in contrast Roger said he has never spoken with you about his turbos. During our staff’s conversation with him today he mentioned knowing of you, but made no mention of being good friends with you.

A representative reached out to the company you stated did the work of rebuilding the turbos, SL Turbos in Sweden. The owner, Stefan, confirmed with us that there had been no turbo failures to report or bearing clearance issues of any sort as you stated. The pictures you provided are consistent with the symptoms outlined by our previous response and that our solution of increased oil restriction solved. Roger is now using the recommended oil with our provided restrictors and his turbos are performing flawlessly. Stefan confirmed that these turbos were NOT rebuilt due to failure as there was no failure.

In addition, these pictures and the information you have shared were not provided to you by the owner of the turbos and are not consistent with what the shop who disassembled the turbos has stated. We have spoken to both parties today and they have both confirmed this.

Stating that you “do not want to throw crap” at our products or brand does not change the fact that spreading misinformation about our products and giving credence to falsities does just that. You are a third party without full information, please refrain from representing your statements to be true and complete when you have only partial or incorrect information. Your word is not to be taken as more accurate than the owner of the turbos himself. When put in context, your statements appear to show that you may have an agenda, we hope that this dispels any future efforts to spread information that is not true.

Again, for transparency’s sake, we will continue to respond directly to accusations made with false pretenses.

[bracer]

As someone who has been dealing with Kratos lately I can personally say they have been super straightforward, ethical, and super responsive to deal with. Down to their engineering even calling to discuss how I was going to be using them and how their testing went.

Time will tell their longevity, but if they designed them with anywhere close to the same level of detail as their customer service and support has been I think I'm in good hands.

Ok, good. Sorry for my bad explanation about the bearing issue. I guess i explained it wrong. Swedish you know.. As i got it explained to me there was some bearing seal that wasn't properly installed but we should not dig deeper into that.
As the problems are solved now it's all good. I didn't speak to Roger directly but to the guys at Trollspeed who installed the turbos. And i must say to your favour that i am impressed of your response to Roger about this. That tells me that you are a good and responsible Company who cares about your customers.
Lika i said earlier, anything can happen but if you wouldn't handle this like you did it would have been bad but you have shown very good responability and great feedback so all credit to you. That is something i will take with me when there is turbo upgrade discussions in our European BMW M-forum.
I wish you a good day!

Car made around 500 on the wastegate spring. Port injection and boost target are setup and the JB4 is working properly with the fuel controller finally (1st issue weeks ago was a faulty controller) Should have larger numbers soon after the holidays and once I get it back I'll post a lot more don't worry not trying to rush the process

I actually ordered the docrace kit and spoke to them a number of times only to change my mind and go with Kratos because of the ease of use of the ewgs to hit my power goals 1100whp+. Let's be real most of us (not all) pay for the Kratos to hit big power or eventually hit big power.

I still have my Kratos, they are currently on a test car that agreed to help me do some testing on them while my car was still in the final phases of being built.

During this time, I've seen a pretty well known s55 running Kratos have a couple of failures trying to push these turbos 40psi+ (the marketing post from Kratos showed this and more). Considering my power goals are 1100whp + SAFELY, I now have 8k Kratos paperweights. They're pretty, though. This isn't hot air (no pun intended) - just see how many kits were sold on the used market recently without even running any events. Really interested to see how Docrace does.

We would like to shed light on the situation that the forum @M3atl user is talking about here.

The set of turbos the user is talking about suffered a failure due to oil contamination at over six thousand miles of use. Metal fragments within the engine assembly were sucked into the turbos through the oil feed. These metal fragments scored the outside of the bearing carriers and caused the carriers to become offset within the bearing housing. The offset was so minimal that although the compressor wheels did make contact in specific spots of the compressor cover walls, it did not warrant the compressor wheels to be replaced but did cause issues with the piston rings on the turbine shaft. While @M3atl may not have been aware of this for various reasons, this was the cause of failure on this set of turbos. This was well documented to the owner with a full service analysis breakdown, list of parts replaced as well as pictures of the disassembled turbos showing scoring on the bearing carriers from external metal fragments as well as the bits of metal fragments.

We diagnosed the turbos and repaired them free of charge although a warranty service was not required as failure was not due to faults of the manufacturing process or design of our turbos. We did this in good faith due to our relationship with the customer.

After the service was performed the car ran with the turbos for a short while, in which there were no reports of power loss or symptoms of failure. The customer decided to send the turbos to a third party to be inspected due to a reported whistling noise coming from the engine bay that was not diagnosed. When the turbos were removed, the technician reported no oil, no play and no indications showing contact between the compressor cover and turbine housing with their perspective wheels. The client and his technician told us that no turbo failure was found upon inspection but that a symptom of the previous failure was found. Included in the report was missing anodization from certain sections of the compressor wheels; as stated earlier no replacement was needed during the original service as the compressor wheels were still able to be balanced. The missing compressor wheel anodization is completely explained by the symptoms of the prior failure and the lack of evidence of current compressor wall contact dispels the notion that a second failure may have occurred. Our bearing technology stops the rotor group from becoming elliptic in event of failure which is why the compressor wheels were still in usable condition after the previous failure.

All of the hardware needed for a rebuild in the event of failure is proprietary and no party has access to this hardware but us here at Global Motoring Group. This makes it completely impossible for a third party to complete a repair of any sort of bearing failure of our turbos. It is also not possible that a compressor and turbine wheel could be replaced as both pieces are proprietary as well. For these reasons among others, our turbos cannot be rebuilt by a third party in the event of bearing failure, which is what the claim is.

Disassembly by a third party without written consent is outside of the guidelines of our warranty policy and voids the warranty on the KRAS55’s. After being inspected by the third party, the client sold these turbos as a working set to another enthusiast on the forums. Their “in working order” condition is telling of lack of failure during the time of their third party inspection.

We believe this to be a misunderstanding due to misinformation being provided by the customer in group chats and other media platforms. It is unfortunate as we believe that we went beyond what was expected in aiding this customer.

[guess2098]

i am the 2nd owner of this turbo. before i install it i actually called Kratos for some installation questions. They told me all the detail about it and they are standard behind their product and offer me a free inspection even though they think this turbo is probably fine.

Dont give me wrong and i do 100% trust the previous owner but just peace of mind having Kratos to check it before install is aways good.

they will provide me complete report and they can share to everyone in the forum.

sorry for off topic but just want share my experience about Kratos so far.

there's always two sides to a story, and thank you Sales@KRATOS for sharing yours. even though I had a slight displeasure with my personal order to shipment experience, I'm not going to let one person's attitude change my whole view on the company.

There aren’t many companies that give you good support as the 2nd owner, but Kratos and Pure are two companies that too. It will keep resale values on both products at a good level

This was well documented to the owner with a full service analysis breakdown, list of parts replaced as well as pictures of the disassembled turbos showing scoring on the bearing carriers from external metal fragments as well as the bits of metal fragments.

We diagnosed the turbos and repaired them free of charge although a warranty service was not required as failure was not due to faults of the manufacturing process or design of our turbos. We did this in good faith due to our relationship with the customer.

After the service was performed the car ran with the turbos for a short while, in which there were no reports of power loss or symptoms of failure. The customer decided to send the turbos to a third party to be inspected due to a reported whistling noise coming from the engine bay that was not diagnosed. When the turbos were removed, the technician reported no oil, no play and no indications showing contact between the compressor cover and turbine housing with their perspective wheels. The client and his technician told us that no turbo failure was found upon inspection but that a symptom of the previous failure was found. Included in the report was missing anodization from certain sections of the compressor wheels; as stated earlier no replacement was needed during the original service as the compressor wheels were still able to be balanced. The missing compressor wheel anodization is completely explained by the symptoms of the prior failure and the lack of evidence of current compressor wall contact dispels the notion that a second failure may have occurred. Our bearing technology stops the rotor group from becoming elliptic in event of failure which is why the compressor wheels were still in usable condition after the previous failure.

All of the hardware needed for a rebuild in the event of failure is proprietary and no party has access to this hardware but us here at Global Motoring Group. This makes it completely impossible for a third party to complete a repair of any sort of bearing failure of our turbos. It is also not possible that a compressor and turbine wheel could be replaced as both pieces are proprietary as well. For these reasons among others, our turbos cannot be rebuilt by a third party in the event of bearing failure, which is what the claim is.

Disassembly by a third party without written consent is outside of the guidelines of our warranty policy and voids the warranty on the KRAS55’s. After being inspected by the third party, the client sold these turbos as a working set to another enthusiast on the forums. Their “in working order” condition is telling of lack of failure during the time of their third party inspection.

We believe this to be a misunderstanding due to misinformation being provided by the customer in group chats and other media platforms. It is unfortunate as we believe that we went beyond what was expected in aiding this customer.

This post is really my experience with Kratos and how I'm excited about the Docrace results (finally). Not sure why it needs an essay reply.

I know Ricky. And we know he has a supremely well built engine by Steve Dinan that's still running hard now on different turbos, unfortunately for Ricky.

You're saying there were metal fragments in his oil, fair enough. I find it hard to believe but it's not my car and I am not based in that area.

I'm not going to go too far off on a tangent - I'm not an active forum user but wanted to show excitement for Docrace cars finally coming out with big results (can't say the same for Kratos). I would be remiss if I didn't call out our direct communication, Abid, where you said you marketed these turbos for 850whp and that taking them above this is taking it out of its efficiency range (fair enough), but saying you put this everywhere on your big power dyno runs that you marketed is patently untrue - those posts were wholly about what these turbos can do (1100whp+)with the right mod list, and we assume, safely. The question then becomes how safely can the turbos make 1100whp + and for how long? We haven't seen any results yet.

Again, back to Docrace, it's great that tuning has finally been worked out and all of the people who wanted turbos with their electronic waste gates no longer have to worry about getting those turbos. I might. I'm clearly in the market for turbos as my pretty Kratos turbos are just eye candy now (that's my decision - ymmv).

@M3atl, we simply want to shed light on the situation you mentioned and clarify any misinformation or misunderstandings that may be occurring. It is important for us to make sure that the information regarding our products being provided is complete and accurate.

We are not questioning the quality of any other vendor’s products, we are simply reporting what the findings were upon disassembly of the turbos you had made mention of.

Abid is within our engineering department and does not handle our communications via social media or the online forums. Our social media and online forum correspondences as well as marketing strategy are handled by our sales staff. What you may be referring to is correspondence had via Instagram. Our KRAS55Bi’s are rated at roughly 85% of maximum efficiency. We rated this system at 850whp+. A dyno of one of our development cars producing 1,066whp at max efficiency was provided to showcase what the max efficiency of the KRAS55Bi rotor group is. All of our 1,100whp+ dyno graphs stated that this was beyond the max efficiency.

To be clear, the turbos in question did not have issues of reliability relating to their continued operation beyond the max efficiency. Their fault was due to engine oil contaminants being lodged within the bearing carrier as previously stated.

We are sorry to hear of what your opinions of our company and products are and hope that the party who currently has the turbos you purchased enjoys them.

Who in their right mind would pay 8k for turbos that can do 850whp (rhetorical)? We have plenty of those options for half the price. Either I don't have a right mind or I was duped. I know the answer.

Good luck with selling more 850whp turbos for 8k. Clearly that's how you wanted to market them.
