Before I shut 'er down I taxied down aways to let 'er cool a little, but after I did shut down and looked under the cowl I realized that the turbo was still glowing red hot (it was well after dark so easy to see through the seams in the heat shield), so I quickly restarted and ran at an idle for another 5 min to keep the oil circulating through the bearings. Anyways, my point is that the stock heat shielding seems to work fine. Maybe I'm missing something here, but I think it's the easiest solution. S.
