(11-06-2009, 04:22 PM)300SD81 Wouldn't the huge amount of excessive fuel cause it to cool down? I thought that was why the Finnish superturbos smoked so much.. to use the excess fuel as cooling.
No. Excessive fuel is to help spooling up big turbos and it produces much heat. Lean AFR (as it is in basically every stock diesel engine) cools the engine and is good for fuel economy.

When a good fuel economy is wanted with a VNT, one has to keep EGP down on part throttle. It helps spool up not to have the vanes open all the way, so the turbo is not standing still but on standby. You know what I mean. I found out that on 606 and GT37v about 0,5bar EGP was a good compromise.

When I struggled to get the GT37v to spool up, I tuned up the fueling as seen in many Finnish MB videos. It did help indeed, boost became about 500rpms earlier. As I don't want my car to be such a smoker, I went back to bad spool up and less smoke..

With smaller VNT turbos that kind of smoking will get the vanes stuck pretty quickly -- but as they spool up nicely even without smoke, why even bother.
