[net.auto] Turbo cooling

[don't bug me now I'm busy]

Mitsubishi, who provides all of Chrysler's turbo boosted engines,
strongly advises its car owners to both warm up and cool down the
turbo before and after driving. They have sent me no less that 3
letters, (one every six months,) telling me to do this. It kind
of makes me nervous, except that they keep extending the warranty
on the thing also (now it's good for 5 years.)

The turbine is spinning at some rather high rpms, it gets extremely
hot, consequently, you have to get your oil pressure up to normal
before using it, and you also want to let it cool down slowly.

Performance always has a price.

Say WHAT????   I don't recall Mitsubishi's logo on my Turbo 2.2L.

WRONG!!!!!!! Mitsubishi has NOTHING to do with Chryslers turbo! It
was designed by Chrysler and is built by AiResearch. The 2.2L engine
is built by Chrysler NOT MITSUBISHI!!!

Is this true?  I mean, the part about 'bishi providing *all* of Chrysler's
turbo engines?  I thought that the 2.2L Daytona/Laser turbo was Chrysler's.

Mitsubishi DOES NOT make Chrysler's turbomotors; they are all
in-house creations.  Iacocca does buy Mitsubishi's 2.6L engine,
though.

Mitsubishi *DOES NOT* supply the turbo engine in the Daytona/Lazer.
The 2.2L engine in those cars! The engine, associated engine controls, turbo-
charger, and all are designed and manufactured by Chrysler.  The turbo
engines in the Colt Turbo, and the Conquest Turbo are engines
supplied by Mitsubishi, in fact, the both entire vehicles are
manufactured by Mitsubishi for Chrysler as import cars.  The Daytona/Lazer
is STRICTLY of American design.

Regarding turbo cooling on the Chrysler products (not the Mitsubishis)
there is no mention in my  Turbo Daytona owners manual concerning having
to cool down the turbo after ANY type of use.  I assume this is because
of the water cooled turbocharger bearings.  I, though, for safety's
sake, leave the engine run at an idle for about 30 seconds before shutting
the engine off after I've been out for any speed/acceleration runs.
I also use Turbo rated oil, which supposedly is able to resist the
higher oil temperatures in turbo-cars, and change the oil and filter
religiously every 2 to 3K miles, even though the manual recommends changes
every 5K miles.  As stated in a message some time ago, performance does
cost - if you don't like to change the oil in your car, or aren't willing
to take steps to help revent premature failure of certain components in
the engine, you shouldn't be driving a performance car in the first
place.  Plus, I don't consider my Daytona to be a real 'performance' car.
It's my every-day-driver car.  It gets good mileage (All around average
of 27 MPG, with best of 42), handles well, is very comfortable for my
1 hour commute to work, and has so far been very reliable (27.5K miles
in 1 1/4 years with no failures).  If I want REAL performance, without
worrying about turbo fragmentaion, blown head gaskets, toasted oil, or
the like, I just wait for a nice day, and get out my '67 Camaro with
the 375 Horsepower 396 in it and have some REAL fun.

Wrong Wrong Wrong! The only turbo boosted engines that Mitsubishi
("Flom re peopre that blought ru Peal Harber") supplies to Chrysler are
the ones in the Conquest (atom for atom compatible with the Starion) and
in the Colt Turbo. All the 2.2l turbo motors are blown with good old
Garrett AirResearch turbos.
