<VV>Mo Fan

>  I know the fan HP is modulated by the  damper doors,

Actually, blocking the output makes the fan loss go up not down and 
increases residual heat. Anyone with an old tanl vaccuum can see - block 
the input and the rpm (inverse of load) goes up and the tank cools. Block 
the output and the rpm goes down and the tank gets hot. Is why an efficient 
turbo has the throttle plate on the input side. It also reduces turbo lag 
since the wheel is already up to speed but that is a whole 'nother issue.

Suppose that since the doors are to warm up and the increased plenium 
pressure is good for heat, this is not a bad thing, just the hp required 
with a blocked output goes up not down.
