How many are running Turbonetics turbos? Namely the "Ultimate" Ceramic Ball bearing ones.

I went to turboneticsownersclub.com and a couple guys are having consistent problems with the bearings wearing out REALLY fast. I'm one of those guys as well...

I built my whole system.. I did... not quite a remote mount system, but a "mid" mount.. with a Small-Ish 62-1 turbo. I do have the NON PI heads on my 97, so the flow will be reduced a little at the same PSI. I'm only running 8lbs ... so that would equal around 40lb/min at **.6bar. I figured I'd go for a smaller turbo, and try to get instant spool, and thats what I get... when the turbo is NEW.

The turbo only spins 80k rpm at my boost level.

I blew 2 turbos, me and my buddy found that the checkvalve I put inline with the oil feed was cutting off oil flow. It's a ball n spring check-valve and I guess the pressure was snapping it all the way shut, choking off flow to a little trickle out the oil exit side of the CHRA.

Now... When I got my new ReMan'd turbo back from turbonetics... I made an Oil restrictor using male/male pipe thread. I welded a glob in the center and used a drill bit about .090 of an inch. Just under 1/8

Now... We measured the oil flow coming out of the CHRA before with the checkvalve, and after with the restrictor I made.

I was getting maybe 10ML of oil a MINUTE before. I should've checked when I first fired up everything In July

With the restrictor, I was getting 13ML/sec ... a cunt hair over the flow rating turbonetics used when they balanced the turbo. So we thought we were golden with this turbo.

With it being a remote mount, It doesn't see the huge heat that conventional setups have. I still opted for the "WET" CHRA. I let my turbo cool 60 seconds after hard runs...

Each turbo lasted 2-3 months apiece. The increased oil flow didn't matter for some reason this time. I'll have to get it warrantied again and ask them what's up.

Anyone else having issues with ceramic B/B hairdryers from Tnetics?

Oh.. and a side note: one of the guys who was having the same issues as me (4 turbos in 1 year) said that he had ZERO problems with the standard journal bearing chargers.

Turbonetics claim the B/B design is 600% stronger than std bearings!!! .....

My oil pressure is also always over 70, even when hot at idle. Gets as high as 100, when it's really cold out.

DallasGT01

what kind of power are you putting out...

are you allowing proper cool down time and everything???

ive been running my turbonetics for about 2500 miles now, no problems.

are you absolutely sure your 62-1 turbo is not too small for your 5.4l?

there was a guy that tried a t57 on his 5.4l and blew it up quick. just too small..

do you have a restrictor on the turbo oil inlet or anything?

proxrsledhead

Well that's the thing. When my turbo is new, I can get it to boost all the way up to 8psi easy. Last week, I could get it to boost to 7 lbs with a lot of lag.. and I usually don't have any lag. Yesterday, and a few days ago... I've been only able to get it to 4Psi...

This thing is pissing me off like no other!!! Lol.

I've came up with a few little theorys...

1) Cat's becoming clogged. STOCK CATS! 149k on motor.

2)Dirty air filter. I put in a new filter, it's a little on the small side, but it's up and away from the road. This new filter ..I put on 3-4 weeks ago...(I F*cked up w/ the placement of the turbo ... inlet is 3-4 inches away from theframe... so I ordered a custom K&N filter)

3)Sh!t bearing design from T-netics.....

4)Boost leak. I checked, All silicone hoses nice and tight. No holes in pipes....

5) I switched to -20F washer fluid. Less methanol to burn to make exhaust pressure?
I added a couple bottles of yellow HEET to increase meth content... but no results.

6) My truck hates me!!


I can hear my wastegate opening very easily. 50mm ..., dumping to atmosphere... VERY AUDIBLE.

Bah. I'm thinking about getting a "Precision 67mm turbo".. or a 70mm. Not sure, but I gotta get this one warrantied probably, sell it and get a different one..

proxrsledhead

Yeah... the 05+ mustang GT kits from Tnetics uses a 60-1..
the 62-1 flows about 10% more than the 60.. And I got the NON pi heads so.. I'm sure the flow ratings are close. I plotted the flow ratings in the compressor maps.. and yeah it should be good!

Yeah ... I get about 3-4k miles out of each turbo it seems.

TJ03f150

i really think u should be running a much bigger turbo, OR if anything bigger on the exhaust side. .58 ar is just wayy tooo small, but i dont know... i wouldnt run anything smaller than a t70 on a 5.4l

what brand of wastegate are you running? it hasnt been damaged or anything i hope.

i had some problem when i ran a turbosmart wastegate, we popped the diaphragm(sp) inside. so i then put on a tial and all is well.

TJ03f150

yah but a 4.6 and a 5.4l are a lot different right? i mean a 5.4l is a pretty damn big motor!

ive got a 4.2l and know of a few people running 60-1 on 3.8's and 4.2's

proxrsledhead

Yeah I was thinking that. but the compressor map plots are within the ranges.. I don't think it could be too far astray from them.... on my NON pi motor the flowshould be around 40-42lb/min at 8PSI ... **.6BAR.**


Compressor map:



bah

proxrsledhead

oops wrong pic. ill be back later. going out!

TJ03f150

I think your exhaust on the 5.4l would need much more than 40-42lb/min. i was told my v6 needs a turbo that can allow no less than 50lb/min.

and 8psi is not 1.6bar. its going to be .6 bar which will be 8 point something psi.

if the turbo spools up to 8psi with 40-42lb/min what about when your truck pushes out more exhaust? the turbo wont be able to handle what it should right?

also im concerned that your egt's may go to high and cause your valves to warp and then eventually result in blowby.

proxrsledhead

Haha, I was drunk when I posted all of this. more so towards the end... and Idk what I was thinking when I said 1.6BAR. Me and my roomie went to the bar.. anddd had a pretty sweet/wild night.

So yeah ... OOPS! The stupid things alcohol does to ya..


*edit* oh .. I was probably thinking about the pressure ratio on the compressor map... ...

* Oh.. and about the EGT thing. I got water/meth inj so EGT's should be good to go. =)
*the 40-42lb/min I calculated was at my rev limiter/shift points... 5000rpm

nice avatar. lol =]

lolwhat...tigol bittiez..lol...haha get them!

Yeah, Trucks pretty picky it seems. turbo HAS to be hot.. (.. like run on highway for 3-4 minutes... w/ bunch of throttle)... and intercooler has to be cold to produce boost... haha i dunno. I'm might just do away with this remote mount ****... and flip some headers & do conventional.

Nice pics! hah.

TJ03f150

i noticed boost shows up a lot quick after ive been running it.

I ran a lightning the other day (a member here actually)

and wow after we ran several times my boost was extremely responsive.

it was crazy.
