<VV> LM turbos and no lower shrouds

[jvhroberts at aol.com]

 The cooling wasn't adequate when it was stock either. Run it hard, and CHT went through the roof. And yes, deflashed, all stuff in place, and no lower shrouds. Things were worse with the shrouds in place. 
I ran mine with and without a muffler, the difference wasn't noticeable except for the sound. 
Now, one idea I never got around to trying was putting the turbo outside the engine compartment. After all, that red hot turbine housing is heating all that air entering the fan!!

I think we are narrowing in on my point -- John's car is not 
stock.  You start changing mufflers, carbs, likely more ... and then 
perhaps the cooling is not adequate.  And no, it is not an old wives 
tale.  My 81 3B Toyota diesel use a different "high restriction" 
muffler if it is turbo charged than when not.  It is not hard to test 
-- take the muffler off and watch your boost, then try again with a 
turbo muffler.  Again, that is something I keep stock because I am 
not re-engineering my car.  I bet it is fun with that SU -- the 
problem is that no Corvair built will out accelerate my pickup truck, 
so I am not sure the point ;-) E
