Comp turbo failure less than a mile

Elmo370z · 08-07-2017, 05:37 PM

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?

The Precision turbos perform equally or better than the Comp. The benefit of the Comp is not requiring the oil system. I was never a fan of an oil-less turbo. That's a lot of heat to deal with to not have proper cooling.

I've never really felt ok with an oil-less turbo. So, you add grease every few thousand miles, but you never open it up and clean out the old grease - how does it not turn into a sticky gummy mess after 30k miles?

For the industrial bearings I've worked with, the new grease pushes the old grease out the sides of the bearing (or some type of vent). In the case of a turbo, I would assume most of the grease will ooze out on the exhaust side and be sent out the tailpipe.

Based on my experience with high-temp bearings, I would give the bearing a shot or two of grease* much more often than 3000 miles. Maybe once a week for a DD.

YMMV. All my experience is with industrial equipment and not turbos.

* Just how much would depend on type of bearing, size, etc.

In most bearing set-ups that I have dealt with. There is a hole that has a pipe plug in it that has to be removed when greasing the bearing. The hole is 180deg from the zerk fitting. This hole is where the old grease is suppose to come out of. If the old grease is hard. You have to use something to poke a hole in the hard grease to get it to flow out of the hole. An auto-greaser might work. We was trying these when I retired.

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.

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.

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....

knuckles899 · 08-07-2017, 09:11 PM

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?
