thataaaat's not right... are you sure it's getting oil ?

you should pull off the oil supply line and point it in a bucket and idle the car  for a bit to make sure there's oil coming through, obviously don't rev the car like this, just make sure there's oil flowing

Im pretty sure there was another thread that someone asked about this and the end result was that yes it will spin but very slowly. i might be wrong but thats what i remember

Mine stops very abrubly, does not move at all and is hard to turn by hand. O well I guess I will just wait until it does stop spooling and buy a SC61... Thanks.


But if anyone else does have this turbo can you check for me? Thanks in advance.

are all ur clocking bolts tight? i know when i was installing mine i was trying to get it to spin and it was tough to get it going.... well they werent tight and i thought something was wrong but the center section was pinched up against the turbine housing... just a thought:angel:

i know the feeling i did the same thing when i shook a bunch of bolts.... actually just shook the only one i couldnt get out and lockwash tonight... ironic... check the compressor housing as well that will stop it from spinning if its pinched slightly too

my bolts arent as tight as they can go(got a problem with over torquing things) just go hand tightish no limp wrist and that should be fine... they arent under as my pressure, heat, etc. as all the other hotpart bolts

do you have a journal or BB turbo? the journal comes standard

BB E50 .63A/R 50trim. Not 60Trim they were out and I got 50trim

something is definitely up I had the same size garret BB turbo for my first kit and it spooled hardcore at idle.  And even after turning the car off it would spin for like a good 1-2 mins.

I definitly think something is wrong. There is very minimal shaft play up and down but there is absolutly NO shaftplay side to side. Thank you for all the responces. Any other ideas please let me know.

BTW my idle is raised to 982rpms which is why I am worried that something is wrong. at 800+rpms it should definitly spin.....

the title of this thread should be "i have a broken turbo"

A 50 trim BB turbo should spin at idle. My 57 trim spins fast at idle and sins very easy by hand. It'll spin for at least a min. after I shut the car off. Your turbo is busted. If it spins hard by hnad, its fucked. Talk to treadstone, I doubt they'll do anything but maybe since its been less than a year. But you shouldve had it fixed in the 1st place when you noticed it.

thanks for all the input. I think I will jsut keep running it until it completly stops and then buy a SC61 dual BB.

Well here goes. I bought the treadstone kit brand new back about 8 months ago and when I first started (yes I charged the oil system first) the turbo spun for about 20 seconds and then it decided to STOP. I reved the car to 2500 for 10 min for proper turbo break-in period and never thought anything of it. So today I changed my sparkplugs and I took off the air filter+tube just to watch the turbine spin and what do you know it spins for about 10 seconds after start up and then it stops spinning. The shaft itself is pretty hard to spin by hand and if you rev really hard to say 5K rpms and let it idle again the turbine will spin for about 30 seconds or so and then it stops. I have had 3 boosted vehicles and all of them (even the journal bearing turbos) stayed spooling at idle...

I thought for sure I have a bad turbo but when running on the road it spools just fine and holds 10.5psi perfectly. What do you guys think?

Anyone with the BB tubonetics E50 turbo can you take off your air filter and see if you turbo stays spinning while at idle and also when the motor is cold is the turbine hard to spin or does it spin freely?


Remember this turbo was brand new when I bought it.

HELP!!!???

I know this response will get everyone's panties in a bunch, but whatever. I think you and eveyone else who worries about their compressor wheel not spinning at idle is a f@cking retard. If the damn thing builds 10.5psi of boost and holds it with no problem, then why are you still worrying and obsessing about it? Maybe it's just me, but I've never even bothered to look and see if my wheel spins at idle...what's the point? The car builds boost under load and runs like a scalded dog so I could give a fuck or less about what it does while the car is idling. Sorry to be a jerk(but yes, it is intentional) but this has been beat to death over the last few weeks. And if you keep reaching in there fidgetting and fooling with your compressor wheel to see why it WON'T SPIN @ IDLE!!??, that's gonna wear your bearings out faster than anything else.....end of rant.

He said the turbo builds 10.5psi of boost and holds it to the redline....does that sound like a busted turbo to you?? Stop being an idiot...You've had a turbo on your car a few weeks, right? I've had one on my car for over a year and 15k miles. My dad bought our families first turbocharged car when I was like 5. I know a lil bit about the subject. If his turbo builds boost and holds it and the car is pulling healthily, there's nothing wrong with that blower. If something was misaligned, the compressor wheel WOULD HAVE PROBALY hit the walls of the compressor cover by now, and fucked his wheel up. Worryin' about why your compressor wheel doesn't spin at idle is ignorant to say the least. Worry about how the turbo operates UNDER LOOOOOOAAAAAAAD....THAT is what matters.

I was trying to make a point that I had been around boosted cars for QUITE awhile...I know that they are built with different bearing clearances and such, and just because 1 type spins easily at idle that does not mean that all of them will...Look, there are ppl here saying that their turbo does and DOES NOT spin at idle....What could be wrong with a turbo that builds boost under load and holds it to redline?? PLEASE inform us. Yes, the seals could be shot, but then it would still boost fine, it would just smoke like a freight train. If the bearings were shot, he would have ALOT of shaft play and possibly a fucked up compressor wheel...has he mentioned EITHER of those problems?? If he has, I haven't read it. He's worried simply because the wheel doesn't spin the whole time the car is idling. I'd be willing to bet that I could go pull the intake pipe off my blower and my turbo doesn't spin at idle the whole time. But whatever, you know more than everyone else, including ppl that have been around this type of shit for much longer than you. I'm not a johnny-come-lately... I've been around the performance car scene since I was a little kid, and I'm fixing to be 30. OMG...I'm a fuckin' idiot.
