             Matt,
             I'm no expert on Turbo, but I believe that some turbo's are
        already
             remotely
             located in some cars.
             There will be some loss of exhaust energy over a distance,
   but that
             is more
             than offset with lower heat, greater life expectancy, and for
             normalizing
             (higher RPM) it's the way to go. Now where to put it is
   another
        matter.

        Thanks George.  I agree with you.  Maybe the benefits outweigh the
        risks..

        I posted this a few messages ago:

        They have a remote mount turbo system, not that I am saying any
   single
        component from them would be useful on an airplane.  Just that
   such a
        system has been used and apparently it performs well enough to
   sell..
        The pictures on their website are intriguing.


        Regards,

        Matt-

        Here is an interesting diagram.

   The ducting is 'voluminous'.  You can see why the Jug was such a chubby
   bird when all of the ducting is shown..  Kind of have to design the
   airframe around the concept.


   Matt-

   The P-47 pilots said it was far superior to German aircraft at high
   altitudes.
   Big problem was it did not store enough fuel for all that HP so the
   range suffered.
   The P51 had a big tank behind the pilot. It also had only six
   machine guns
   instead of eight in the P-47 leaving more room in the wing for
   tankage. In addition
   to that the P47 had about 2000 HP while the P51 only had 1500 HP.

Just another example of how all designs are compromise..
