I purchased precision sc61 a couple years ago, about 4 months of on and off use, the turbo turbine wheel snapped off. while driving on the autobahn passing a car at about 200 kph. I sent the turbo in under warranty they blame it on oil starvation. my car puts out 65-70 psi of oil I only use mobil 1 synthetic oil. then they try to blame it on the location where it was fed, saying that oil pressure sensor is feeding the turbo dirty oil. they repaired it under warranty so I switch the feed to a Golden eagle sandwich adapter. 3 months later turbo started smoking (note I don't drive my car daily) sent it in for repairs they repaired it and blame it on the location again, saying the sandwich adapter is feeding the turbo dirty oil, and not giving it enough. I have a gauge between the turbo line and the fitting on the adapter.
a few months ago turbo started smoking again. then it gets really bad, I was testing a boost controller one day and the boost got up to 14 psi. and the compressor wheel broke off, turbo still spins freely, but has a lot of shaft play.
sent the turbo in and they sent it back to me saying I have to pay $800 dollar to rebuild it, because its oil starvation, they did not even inspect the turbo. I know because all my bolts are still painted like I sent it in.

 

 

I know I will get bashed, and because they sponsored and moderate this forum I might get banned but where is the lost?
at least I let everyone know whats up.
my friend also owned 2 precision turbos that went bad after a short time of use also.
but instead of owning the problem and do something to fix it, they blame the customer.

Looks like it got pretty hot bro...

I've used/sold hundreds of PTE turbos over the years and I've only ever seen a couple legitimately fail.

They are great at customer service...why should they keep sending you new turbos when you keep destroying them?

In typical honda-tech fashion, 'PTEs are junk' and it's complelely inconceivable that you are just an inexperienced moron who doesn't know as much as you think about turbocharging.

Dont worry about that. If there is a problem with a product, its for the good of us all to know about it. What do you plan to do now?? I wouldn't be running another Precision unit after all this...

 

years back i had one go out on me. just the seals went back. They didn't really give me any issues. they replaced the seals. I sold the turbo while it was at precision so i don't know how long it lasted cause they shipped it straight to the guy.

I expected that, so I won't get mad. you a dealer you supposed to defend them. I won't even bother to defend myself on that coment. I just wanted to let it out instead of keeping it secret.

 

judging from those pictures that thing got pretty hot.

if you are damaging the turbo's that fast i dont think its the manufactures fault. you need to check your installation and setup.

 

I do took advise from PTE , I beleived the turbo failed from too much oil, but they insists that its oil starvation. so I run it straight without a restrictor. so the seal blow fast. they keep telling me that their turbos see 100+ psi daily without issue.


don't get me wrong I still use their injectors and I love them. and I still love the fact that their turbos puts out more hp than the average tubo. I made 440 whp on 14 psi on this same turbo. but they are fragile and they need to fix it.

I am not a turbo expert, but I am not an idiot, I am a certified mechanic. been a mechanic for 8 years, I know how to install a turbo setup, I don't need to pay someone to do it to ensure its done correctly. my name is not big but I can build turbocharged and tune a honda correctly.

 

seems like alot of people having things come up about there turbos out the blue and in the pass year i have never had any thing happen to them and i have used over 20 of them

 

Can you post up some pics of the setup, feed, return and whatnot? Just a thought, someone might see something overlooked. You seem kind of close minded about there being an issue with your setup, I understand your a mechanic but sometimes things get overlooked.

In my experience precision turbos are quality unit not trash (I am no dealer, just a consumer), I dont discount the chance that with the thousands they manufacture there is some limited chance for some issues (its not a perfect world) but multiple turbos in a row so quickly seems odd.

I have owned and ran 4 different precision turbos over the last few year and I know of probably 12-15 more on cars of people I hang out with over the last couple years (evo's/ dsms, mustangs, hondas, f body, etc). Never once see any issue like that... in fact their customer service was extremely helpful whenever I called. I got knowledgable answers and treatment.

Sorry to see your going through turbos so quick. Hope you figure it out so you dont put a non precision turbo on and cook it too.

Dude, just look at the discoloration on the shaft. There is NO WAY that was over-oiled. That's oil starved for sure.

 

im running precison sc34 and run it daily and no problems. I run it once a month at the track Im boosting 15 pounds daily driver. Im running oil restrictor so I would recommend that

 

You should send them a picture of how Honda engine blocks work. Oil pickup --&gt; oil pump --&gt; main galley --&gt; oil filter --&gt; up/down to head/crank, and the sender location is after the filter on the way to the head. Also the GE adapter is one of the post-filter oil supply units, not a cheap unit that supplys pre-filter.

If the oil it's getting is dirty, then ask them what filter to run to get clean oil, since your filters are bypassing all oil around themselves (if precision is correct).

I would appear that your seals **** the bed, then a little crank case pressure helped push most of it out of the seals rather then 100% through the oil passages. The oil passages hit the outter race 1st, then dump inwards/downwards. The outside is oily, the inside is scared from heat.

 

I would have checked your oil feed line there could be a blockage or a partical in there , b4 you put on another turbo I would disconnect it and run some compressed air through the oil feed line to clean it out , because it does look from not enoff oil , I ran a restrictor on my sc61 and it **** the bed and they covered it and it was way out of warrenty but only had about 1200 miles on it if that , I would say go with bullseye power if they will not help you out , there turbos are realy tuff

 

after the turbo started smoking I replaced the feed line with a new 3AN feed line because I had a 4AN before. then the turbo ****.
I did not went through multiple turbos, this is the same turbo the rebuilt a couple of times, and is suspect that the reason the shaft broke is because it was retorqued a couple of times because of the rebuilds it got stressed.
then when the threaded part snapped off it prevent the turbo from circulating the oil. and and because the seals got blown the oil was bypassed from the shaft which caused the hot spot. also this happened 12km from my house I found the nut inside the air filter.

 

I really did not wanted to start this thread. but I felt that they neglected me as a customer. because they did not even disassemble the turbo to see what really happen. they immediately blame it on oil starvation, I understand the warranty expired. but they basically say screw me and say I need to buy a new turbo, they refused to sell me a rebuild kit so I could rebuild it myself when it first started smoking. then they told me I need to buy a new turbo.
I've already ordered a new turbo, and if the same thing happen to this one I will not know what to say. (garrett t3/t67) I had a used saab turbo lasted longer than the sc61.

dude, who clipped that wheel? it looks like hell....like someone took a dremel grinding bit to it.

I agree with everyone else. Starvation.

Are you priming the turbo before starting the car up? I.e. yanking the fuel pump fuse and cranking the car for about 10 seconds?

Just to answer your question...

So basically the inside of the compressor housing is "who" clipped the wheel

So the moral of the story is actually run a restrictor to save the seals..
What is the reccomended oil press for this turbo?

I HAD THE SAME SITUATION WITH PRECISION , I JUST PAID 800 BUX ON A TURBO THAT SHOULD BE WARRANTIED , BUT MINE BROKE WITH LESS THAT 100 MILES ON IT ,
