<VV> turbocharger cooling

[Dave Thompson]

Seth,

What cool product! (pun intended) However, I like to keep things basic like
GM designed it. Besides, idling the car after a hard run is part of the
experience of driving the car. I may drive her hard, but I try to take good
care of her. Just like proper shutdown procedures on an airplane. I can se
how the product could be a good addition for some people.

I just shut down when I stop. I
use my CHT to determine if I need to idle before shutdown. Of course, if I
had just jumped on it to get some boost, I let it idle or drive moderately
for a few blocks before shutdown.

With the string that is going on here I wonder if I should idle for a minute
or so before every shutdown. What are you guy's opinions on my current
procedure? Should I modify it? If so, How?

"Turbo Power" company used to make a shutdown cooler kit, it included a
small electric oil pump, a temperature sensor and a shuttle valve. After the
engine shuts down, if the controller senses the temp in the turbo exceeds a
certain level, it starts the pump. The pressure pushes the shuttle valve
closed and then pushes a small amount of oil through the turbo to keep some
cooling going on. The oil returns to the sump via the stock drain. When the
sensor reads the turbo has cooled past the set limit, it turns off the pump
and the shuttle valve returns the feed to stock. If more heat soaks into the
turbo and the temp comes up - the controller turns the pump back on to cool
it. The kit was very popular with SAAB owners in the late seventies and
eighties.  Turbo Power no longer sells the kit. They sold the complete
product line to another company. I will try to find out the current supplier
- if someone is still selling it.
