Comp turbo install Error
 

****** Please read post #79 and #82 for explanation for how this was a install error and not a manufacturer defect*******

So for the last 3 months I have been meticulously installing a Boosted Performance turbo kit for my HR.....works been really busy so I've been tackling the install by myself when I have time. Prior to doing the turbo install I dropped the transmission and put in a Southbend stage 3 daily clutch and DXD flywheel, Zspeed HD slave, wilwood MC ect ect.

Today I finally got to the point where I could actually fire her up and drive it just a little bit to check for leaks.......................after letting it idle for 5 mins I decided to go around the block lightly....I only had the base map flashed provided by Sasha and Vince at RT tuning so I kept it light footed.....................

This is where I get really sad now, I made it only about an eighth mile from my house and I started to notice a kind of whirling or howling sound coming from the Comp Turbo (oil-less provided with the boosted performance turbo kit) I turned around and parked it back in the garage and started checking everything out.

I noticed when I removed the air filter for the turbo it appears that the impeller blades have somehow made a grove into the turbo inlet housing....I'll upload pics tomorrow.

What would of caused this so fast? not even getting on it....I assume all the metal shards from the impeller and inlet housing are now located in my engine now......

Sorry for the long post..............just utterly disappointed....didn't now what else to do....its not even about the money.....just all the time I have spent with all this......I guess literally everyone was right about my 350z and what a waste of time and money it would be doing all this to it.

My moping session is over ill get pics soon FML.

wow,,,did you loosen any clamps on turbo to clock it/turn it for piping alignment?
i'm not familiar with that turbo...as you stated oil-less.

1st Turbo i've ever seen that uses high temp grease for the bearings...I'm sure it had to come pre-lubed.

Yeah, it comes pre-greased......i verified by calling CompTurbo a couple months ago.

Heres the pics

I loosened the housing to spin it slightly but that is pretty common in order to align/clock the turbo.

That's crazy; hopefully it didn't force particles into your engine; your intercooler may have caught them.
Pics look as though it's coming apart-wish you Luck on some warranty.
That really sux; as I can relate by performing all of my wrench turning.

Hmmm that makes me wanna check mine now ....I did noticed it howl some and heard some strange noises that I have been looking for...but most have been exhaust vibration ..haven't removed the turbo tho I have about 50 miles on it now.....just making a observation from the pics ...it kinda looks like something mine have been sucked in damaging the blade

Our first Comp Turbo review, lovely. And this is a 350z? Still wondering where all the 370z guys are that have this turbo. I haven't seen anything from them, and it's been awhile since they were sold.

Thank you Knuckles for giving us your experience

Yeah 08 350z HR. At this point I feel as if I've been sold a vat of snake oil from Comp Turbo......

I'm curious on Sasha's opinion about this.....since he backed supplying Comp oil-less turbos with his kit.

How did the car sound when it was idling...

Damnit

I was planning on buying this kit

Let's us know

Normal for a single exit exhaust.

Did you check it for shaft play? That would sound like a siren or warble. When you clock the turbo the only thing that moves is the housing the compressor wheel does'nt move and slides over the turbine wheel shaft. The only bolt that comes off is the one that holds the compressor on and it could be loose but other than that bearing failure? I'd take detailed pics for Sasha and for Comp Turbo then pull the housing to see what happened. But wait till you talk to Comp before doing that.

Be careful with taking the turbo on and off. That cost me a transmission harness. I had fully torqued it several times before the finishing the install and forgot to consider I was flattening the turbo manifold gasket. Had a wicked exhaust leak that was melting everything. The gaskets are relatively cheap and now I keep a couple on hand in my tool box just in case I get curious.

I think you can still get the oil cooled turbos.

I loosen the downpipe and rotated it off the bottom of the floor late last night ....took car out this morning ran about 150 miles normal driving ..boost set at 7 lbs ..everything runs/sounds fine. You can hear the turbo spool/howl spools up smooth and spools down smooth...boost comes on very fast and strong and you can hear the turbo spool down after shutting car off ..not loud just a smooth spool down for a good 20 seconds so I would assume the blades isn't hitting or dragging anything.

BINGO it started to sound like a siren in the distance exactly. I haven't checked anything yet just pulled the turbo out for pics.

Im sure you're fine. It would most likely not be running smoothly into boost if your turbo looked like mine. These little Bluetooth inspection camera/scopes come in handy instead of taking stuff apart....i think i got mine for 50-60 bucks. https://goo.gl/images/itKjdU

I got one of these from Amazon. 20 bucks. It's a bit of a hassle to get it to work with a computer. Once you figure it out. It works great.

duuuuuuuuuuuuude that sucks.

My friend Ryan has a BP kit on his car as well. The comp turbo lasted 10min before it had a internal coolant leak and was dumping coolant into his exhaust.

Is Ryan a member here? When did this happen and how was it handled?

:wtf2:NO bueno, NO bueno

This is just great. There is threads about these and other failures on the SVT, Viper and Audi forums. I'm almost done installing mine as well. Crossing fingers!!

I think those reviews were for the first version, correct? They didn't have the grease fitting. The grease fitting was supposed to fix everything.

Damn!! Well there's still the Precision 62/64/6766 options. I was wanting to bump to 6766 from my 6266 but after some reading I'm digging the 6466. For those who went oiless the install and routing of the exapump is no worse than doing an oil cooler install.

Fact that these turbos are failing doesn't vote much confidence. What other options do we have that offer the same characteristics as this comp oiless turbo?

In for a reply from comp, and BP. Planning on running this kit as well in the next year. I though the grease nipple had fixed most of the issues with it. This problem doesn't sound lube related though lol

3 things with greased bearings. You can under grease them, you can over grease them, and use the wrong grease. All 3 are bad for the bearing.

Comp turbo failure less than a mile
 

I just mean they come pre greased, and comp over/under greased they will hopefully step up. And it's like op greased it at all, if and when he does there are instructions for when and how much plus the grease is supplied. Kinda hard to screw up.

Which is why I wasn't comfortable with Comp's "A couple pumps every oil change" 3000, 5000, 7500, 10000 miles? 2, 3 pumps? Big pump, little pump? Who knows. Even then you have to send it in once in awhile. And guess what they might say if it needs lots of repair? Yep, "you didn't grease it correctly". Anyway, let's see what Comp and BP say. Personally I never saw a good or bad review of these revised turbos. I think we're just now getting a glimpse into what the V2 could be like.

Where I retired from. Electric motors, pumps, and things got 2 pumps of grease every month. This equipment is running 24/7, and a lot harder then some turbos. Each had their own grease. If you got caught pumping more or using the wrong grease. You got wrote up.

With turbos or any high heat app. You use the wrong grease. The grease will turn to wax, then dry up quickly.

I was so excited to start the install on this in a few weeks.... now I'm terrified..

Just wait. I think you should at least get Comp to check your turbo. Or, send it back and go for the oil fed turbos. I would not install a metal spitting blower in my intake.

Yea I'm kind of torn now....

Comp Turbo got back to me today through email. Basically they said sorry I am having an issue with a product... that is why they warranty it for 12 months and to send it back to them so they can verify it.

What is everyone's opinion on cases like this..... Lets say I just dropped 14 grand on a new turn key built engine. Then this happens and POOF money down the drain due to a faulty turbo....I understand the turbo warranty but if it is a faulty turbo how do companies get away with selling a defective product and not get held liable for damages from a faulty product...like an engine?

Can't comment on them being liable for any engine damage, but from what they've said above, they seem to not grasp the difference between a warranty and quality control. They aren't the same thing and unfortunately you've become a member of their, possibly non-existent, quality control dept. I hope it works out for you. We're all watching.

Are you going to remove the intercooler to check for metal? Maybe the oil pan as well?
