What is the max. RPM's for the K03 turbocharger?
Does it spool fast since it's so small?
How much faster does it spool with a chip?

Now you know why it'll glow orange.

I did about 5 pulls on the interstate the other night flooring it to 80 and slamming on the brakes down to 30 (testing brake setup) and repeating. Pulled over shortly after and the turbo was so bright, it lit up the back of the engine bay.

How does the turbo itself glow orange when it has engine coolant flowing through it? (Or, are we talking about the downpipe/exhaust etc.).

The manifold, turbine housing (ie hot side of turbo) and the DP will all glow if you drive hard enough. That's how much heat it is making.

Actually the coolant and oil only flow thru the center section of the turbo, this is the section that houses the saft that holds the 2 wheels together. The part that will glow orange and even white is the turbo exhaust housing which is the part that the exhaust gas flows thru to get to the exhaust pipe.
AXIS, thanks. I just hope to have it installed and tuned in the next few weeks. Still trying to get the car ready for the EC 1.8t challenge that is being held in NJ and I live in Socal.

Does this happen on stock cars or mainly chipped ones? I'd think that with only 0.6 bar (AWW motor) that the EGT's would stay reasonable.
It's nice to know that at least the lubricated parts don't glow in the dark.

It's the turbine housing, not the cartridge.
Audi2ptzero - nice part. What are the specs on it?

push a stock turbo hard enough and it will definetly do it. The pic of my t3 was when it was only running 6psi. It's not only about high EGTs. you can have the same temperature EGTs with a chipped and stock car as long as the A/F ratio is properly tuned.

Not sure what the specs are on the new turbo. It took Innovative some time to get the correct AR exhaust housing. His math says I should make 450- 500 hp running 20-25psi but we plan on pushing that all the way up to 30psi. Later on I might end up o-ringing the motor so we can push the turbo to its limit of 35psi.
