You will spool faster and, if you can isolate the heat radiating from the turbine housing as much as possible you can keep temperatures in the compressor housing and underhood temps in general considerably lower.

True, My turbos mount directly to the exhaust manifold, with about a four or five inch up pipe... Here's a pic...
The heat from the turbine housing isn't really the source of the underhood temps, other than at very low speed... I've not done any actual testing, but numerous friends have mentioned how much more heat my car gives off compared to theirs... I mostly wrote it up the the heavy right foot and the HP this furnace makes...
Edit: the down pipes pictured are 2.5 inches in diameter, we cut those off and put a 3" down pipe in it's place... and three inch exhaust all the way out the back.
Edit: That's actually one of the old turbo's. That's a 62/65, and the new ones are 67/66's
