<VV> LM turbos and no lower shrouds

[jvhroberts at aol.com]

 Um, the stock system is not all that and a bag o' chips. Sorry. For those of us who have turbo cars, etc., the cooling is utterly inadequate. Removing the shrouds produces a noticeable drop in CHT and oil temperature. 
Even on a non turbo car, if driven spiritedly, the cooling system runs out of breath. 

So, there is, in fact a better system out there. GM simply failed to install it!!

I am always puzzled by this discussion which comes up every so 
often.  The car was designed well from the factory.  If you have 
everything correct -- all the shrouds as well as seals and so forth, 
there is no better system.  I am in AZ, totally bone-stock, at 
altitude (3500-8000 feet), summer temps of 110 ... and I NEVER have 
even gotten remotely close to overheating.  Our speed limit is 75 and 
I can go up a 6% grade at 80, no over heating.  From my 3500 to 7500 
feet happens in 6 miles, no overheat even at 80.
