Chris - You mentioned "turbocharger life is cut in half, when not
intercooled".  How does this occur?  I'll admit that my turbocharger
"experience" is limited to attempting to keep #2 daughter's '85 Volvo
760 Turbo perking, but from the looks of the intercooler, all is does is
cool the compressed air coming from the turbo.

How would the turbo know whether or not it has an intercooler "down
stream", other that a bit of back pressure from having to force that air
though the intercooler on its way to the engine?

ps-#1 daughter has what I would call an '85 Volvo 244 with the same
engine but non-turbocharged.  My Volvo guru tells me #1's will probably
will probably be prodding along LONG after #2's will need still another
engine!
