Turbo Corvair Cooling Re: <VV>Has anyone on the list BOUGHT Tom's cooling system

[FrankCB at aol.com]

Crawford,
    I also observed 400 deg.F as the "normal" operating temp on my street 
driven 180.  This was on the stock uncalibrated Corsa temp gauge and a relatively 
stock engine (except for vacuum advance with electronic knock sensor retard). 
 Under full load the temp would rise to 450 deg.F.  But here in NJ I wasn't 
able to keep full load on the engine for very long since the penalty for 
driving way above posted speeds is rather severe.
    My feeling is that the only reason GM "got away" with the cooling system 
on the 180 was that the drivers couldn't keep the engine at full boost for 
more than a short time before running out of road or encountering law enforcement 
personnel (aka "cops").
    At the recent Convention, Tom Keosababian, when asked by some "busybody", 
responded that in his Bonneville runs his water injection usage was 1/3 to 
1/2 of his fuel consumption rate.  So obviously the stock fan setup was hardly 
sufficient to handle the cooling for his high boost ultra high speed runs (157 
mph on gasoline and 173 mph on propane.)

But frankly, even in stock form, I have observed 450-475 degree head temps at 
80 miles per hour with my turbo on boost (summer / conv. top down / all 
shrouds installed).  I think that the fan is fine for its intended use and GM must 
have been satisfied with these conditions for all foreseeable warranty 
purposes.
