<VV> [fastvair] Re: Reverse Rotation Cooling

 It is considered utterly normal operation for most cars. I can drive a 911 like this, why not a Corvair? I can drive a VW Beetle like this, why not a Corvair? I can drive a (insert just about any other car here) like this, why not a Corvair?

              John - In the case of the Corvair turbo it's possible (easy in    fact)  to blow the engine up or melt it down by doing something as    "innocent" as flooring it up a long grade on a warm day to pass    cars.  That does not constitute "normal" operating conditions.

                  Obviously, more open area between the fins, more air                  pressure, or both will improve cooling. Also, the                  location of the turbo itself couldn't be worse, having                  that orange hot turbine housing heating all that                  cooling air before it even enters the fan! 

                  There are many turbo owners who wish they had more                  cooling. The fact mine has more boost and 140 heads                  just makes an already bad situation already worse.

                    Why could you not get your turbo to run cooler?  As                    regards to the fan, if there is pressure in the                    plenum then there is as much cooling as a fan can                    push. Other issues involve condition / cleaning of                    the fins etc.   The Corvair fan is adequate for ALL                    cooling usages - the only question is how to                    accomplish the same cooling with less loss of                    horsepower -an elusive thing.

                    Since many others run thier turbo Corvairs all the                    time without unusual colling problems what were you                    doing differently?

yes, but why change? The std fan provides more than sufficient air to
cool the engine in normal everyday driving for most of us. If you want
to run a cooler engine, take the bellows and doors off the bottom
shrouds, or better yet, remove the lower shrouds, for summer driving.
