I assume this is not good?

Sounds no bueno to me holmes..

I have heard of people being able to see their turbine side (hot side) spinning inside the housing...just what I heard.

SIK IN DA HED

thats crazy.

NeXtLeVeL_TyPe_R

that is pretty crazy

I am asking because my friend has a turbo hatch and we pulled over at a gas station because it was smoking alot and his manifold and his turbo where cherry red hot....we let it cool down and drove right home.

Is this a bad thing --what causes it not enough oil getting to the turbo???
i told him maybe he should check his oil feed line

my bud's bone stock 94 Saab 9000 Aero's turbo did this. the turbine housing glwed red. its no big deal tho, just make sure your turbo timer is working properly

NeXtLeVeL_TyPe_R

is there a good way to prevent it from happening?

dbman96

This happens with almost all turbos. They are made to withstand this kind of heat. Don't worry about it. If you haven't seen your turbo glowing hot, it's because you've never popped your hood at night right after turning the engine off.

NeXtLeVeL_TyPe_R

Yea even if the manifold is glowing hot too....thats surprising and comforting at the same time

This is when manifold construction starts to get really important. A well-made manifold will be just fine, but this is the reason the crappy ones start to crack really fast. If your buddy gets a larger turbine (like move up from a 0.48 AR to 0.63 or from a Stage I to a Stage III) it will reduce restriction on the exhaust and relieve some of this thermal load from the manifold (at the expense of slightly more "lag").

he and i are both running maxrev manifolds
I am gald to see this is somewhat normal i though he may have been running into a big problem

R-1303

i've seen eclipses gst/gsx's run there turbo's to the ground where i lighted my cigerrete on there manifold....but the next day everything seemed fine..just make sure u don't poor any water on it!!! hehe

dbman96

Haha yes do NOT get freaked out and try to cool it down!

Might just want to check the Air/Fuel just to make sure

I have yet to see my turbo glow...... even at night after a long drive with lots of boosting...

Then again mabye because mines oil/water cooled, and possibly also beacause its big? (t3/t04e)

Lamchop0000

maybe its automatic and not reving high enough to make that sucka glow. just a thought

*Boostwerks*

Mines's Water cooled and I've never seen it glow either.

HondaCutter

where do you get the water cool stuff from? Do you use water cooled and oil cooled, or is it one or the other?

Lamchop0000

its in the turbo. some turbo are just oil cooled. and some are water and oil cooled the turbo has 2 passages around the center shaft so oil and water wont get mixed up

the water cooling comes from taping onto the coolent hose lines. if you are asking that

HondaCutter

so can you run both oil and water? what do you use to tap into the coolant?

Lamchop0000

yeh some most factory turbo's run both oil and coolent to cool the turbo. and i think some aftermarket turbos do also. tapping on to the coolent... i think most people use the line from the throttle body, but im not sure if theres anywhere else you could tap onto.

ive seen a dyno run of a supra tt where the wastegate started the glow and u hear that cool wastegate sound after he let off the gas
