"cooling the turbo reduces its efficiency."
I have read about that before. My main concern is to not let the heat sit
and cook the cowling. AS&S sells several types of heat blanket material,
some of which is adhesive backed, rated up to 2000 degrees and seem like it
would work to keep the cowling cool. No one has suggested any thing else
that seems practical and simple. As for my turbo, it is behind the #3
cylinder, but not below. I mounted my last turbo too low and the oil went
into the turbo like an oil sump, and blew oil everywhere on startup. This
turbo is mounted high enough that the oil drains back into the VW sump.
