You cannot have combustion @ the turbo or in the exhaust system when you are running rich unless you have a gaping hole somewhere allowing OXYGEN to be drawn in to allow the process to happen... Unburned fuel turns in to flames once it comes out of the tailpipe and has oxygen. You can however run very lean and have elevated exhaust temps. (If you are a drag racer you would program this via your ecu [anti-lag] to purposely alternate your cylinders rich / lean to get fuel and oxygen into your exhaust to force combustion and spool the turbo sitting still... fine for racing as you are going to chuck the turbo in short order anyways) I would check your oil flow rate before turbo and after pump. Make sure you do not have a sealed oil drip tank and that it is vented to allow the suction pump to do its job. (many people don't seem to realize why Porsche put a vent line on the factory turbo oil tank)
