Primary turbo is starting to glow red in 10 sec if i just standing still in my garage and keeping it at 1000-1500 rpm:s

I have checked:

*TPS.... Ok

*Pressure sensor.... Ok

*wather termo sensor.... Ok

*air temp sensor.... Ok

*o2 sensor.... Ok

*Crank angel sensor... Ok

*New plugs....

*New wires....

*Coils.... Ok

* "Rattnest" ... Ok

* Engine ground... Ok

* Injektors Cleaned and tested... Ok


I am almost sure there is something that gives the engine to much fuel b cause it smells like a dragster

Somebody???

If you have the stock precat,then it is clogged

Throw ice cold water on it.

Just kidding, don't do that Sounds like a clogged pre-cat to me.

mmmmm. hot dogs...



yeah sounds like a cat problem or it's running lean if its not stock rx

Could be as simple as a bad exhaust manifold gasket, and explain the smell. the same thing was happening to my header due to this cause.

Check your fuel pressure.

Your turbo housing was glowing red at idle due to a bad exhaust manifold gasket?

*Fuel pressure.... Ok

The car is stock.

I cant guarantee it, but i think the cat is ok.
The exhaust flows good.

But if i start it upp whitout the downpipe there is fire coming out of the turbos at idling.... = rich.

I have changed ECU also to eliminate that there is something wrong with it

To much fuel.. but why??

How did you check the oxygen sensor?

Ditto for the cat.

You could have a leaky injector.

Yes it was. Actually it was the exhaust manifold (header, non-turbo) that would glow red at idle. But there was enough gap that I could actually see exhaust escaping there in the right lighting. Thus making me think its entirely possible to happen to the turbo/housing/manifold.

I think one of the injectors is dumping fuel.

The injectors may be fine but if an injector O-ring is pinched then fuel can dump into the LIM. I don't know what else would make your turbos glow and your car smell like a dragster than fuel dumping.

if the AFR is too rich the turbos wont glow ... but if the AFR is too lean the turbos will glow

or the cat is broken

Have you checked to see if that particular turbo spins freely?? I frozen turbo will cause a tremendous amount of excess heat due to the resistance of exhaust flow.

Especially since its only happening on one turbo...

extreme_rotary

You did check the MAP sensor hose right? if it is cracked or something and reading too little pressure at idle, it will cause a rich condition. Verify operation with a multimeter between the signal wire and ground. applying pressure to the sensor should increase voltage. key on engine off, should read between 2 and 2.5 volts. verify proper operation of the check valve as well.

I tryed to drive it yesterday... and it was like it didnt accelerate and building boost pressure like a mainiac!!?? 1500 rpms= full boost...

Fjunet

Its like it chokes it self to.... and building much boost like hell!!

i hardly dosent get it to rev mor than 2000 rpms

that sound like your precat is really clogged. change your downpipe and you'll be happy

Gadd

Sounds your over rich condition is acting like a anti-lag. Does the fuel pressure hold when the fuel pump is off?

Yesterday after I had disasambled my intake I discovered that I had switched the cables to the turbo pre cotroll and the wastegate controll....
Can this be something? what are the symptoms??
