turbo fin damage

[bdydrpds10]

Wrenching on the ty today (changing the harmonic balancer) I checked the turbo while i had access and noticed one of the fins is bent. Its a stock turbo on stock truck. No play in the shaft. Should i worry about it?

Re: turbo fin damage

Time for an upgrade?

With that being bent, the compressor is not working as good as it should.
Plus it could break off & wipe out the rest of the wheel.

Re: turbo fin damage

I would check out your intake tube and see if its cracking anywhere. Thats what took out my turbo fins. I sent mine out to Jwaller on here and got a very nice upgraded replacement in return.

Yep, the end of my intake is missing a few pieces but has been like that for several years.

i guess that is what caused this. i cant really see in the turbo wheel so i felt around and angled my camera phone where i could get a picture.

Re: turbo fin damage

The previos owner of my Ty had the intake tube crack and the stock turbo .....FINS are trashed if you look at the turbo, pretty much all the fins have some sort of bend. But......The turbo always produces great boost with amazing spool! I recenlty swapped to a 20g for more power. I ran a 13.5 with the stock turbo and a crappy tune.

I would not worry too much about the one bent fin unless you notice a power decrease

my sentiments exactly if it build boost and its not missing a chunk out of the comp wheel to throw off the balance of the turbo, you should be allright check the inside part of the alum comp ressor housing to see if there is any grindining on the inside part of it, if you do then you will need a rebuild.

What is causing the carbon buildup on the intake side like that? ---

The timing is WAAAAY off. I think that caused the build up. I was trying to do a little tuning when I could not get my timing to set right. Come to find out I can spin my harmonic balancer around with my finger. Im in the middle of replacing it now.

Re: turbo fin damage

It's probably oil film from your pvc valve if you still have the stock set-up,I really dont see how carbon could get to the compreesor wheel
