<VV> Turbo Cooling Question

[Bill Elliott]

Congrats Grant... people that haven't seen (in person) or driven your 
Pantera simply can't imagine the type of car it is... I'm shocked that 
your reserve was so low... this will be a real steal for somebody.

Congrats also on the Turbo PT... if it's lacking anything, power isn't 
on that list. That car will scoot!

Newer turbos are water cooled (and some even have water circulating 
pumps that continue to run when the engine is shut off). This combined 
with synthetic oil (which doesn't coke up when cooked around the turbo 
bearing) means that cool downs are not nearly as critical....but still a 
good idea if you have had the turbo very hot.

Owner's manuals for turbo cars of the last three decades or so have all 
had this advice... and for non-water cooled turbos it was absolutely 
critical.... but I don't recall ever seeing it in a Corvair owner's 
manual. They possibly didn't realize how important it was at the time...

>HI all. Thanks to many who provided insight on the PT Cruiser and HHR's. We purchased a PT GT with the High Output 2.4 turbo engine, select shift transmission, 17" wheels, leather, etc. I'm afraid that when the boost comes in, it puts our cars to shame :-). But then, it doesn't have that great Corvair style and engineering :-). My question is on the Corvair turbo, however. The PT owners manual states that for normal driving, there is no need to let the engine idle prior to shutdown, but if you have been driving "aggressively" for a short period of time or driving with a heavy load (boy that one is open for interpretation :-), then you should let it idle for 3 minutes prior to shut down. If you have been driving aggressively for a long period of time, or towing a trailer, you should let the engine idle for 5 minutes, to allow the turbo to cool properly. I don't have a Corvair turbo owners manual handy, but did it suggest such procedures? Thanks,
