Re: air box failures?

     Duck tape and 5 minute epoxy got me back on the road, but its 
     definitly not a permanent solution. Being near to the Exhaust that 
     black box must see a lot of thermal cycling stress.  I had to use a 
     clamp to squeeze the main crack back toghether because it had warped 
     enough to separate 1/4 inch.  Whether this was caused by thermal 
     stress or molded in stress in the plastic, Duck tape won't hold for 
     long.
        This whole debacle has got me thinking back to good ol heat 
     transfer class in school.  The simple problems were the ones that 
     assumed a 'black body' because it would absorb 100% of the heat 
     radiated to it.  Conversly a black body would emit 100% of its heat.  
     Although in practice there is no such thing as a black body I have 
     seen things that were difficult to cool and painting them black helped 
     noticeably. I wonder if the reverse would help some of you turbo guys 
     in your quest for lower intake temps.  Would liberal application of 
     some metallic silver paint on the EM keep its heat in and on the air 
     box to reflect heat out make any noticable difference? Just some 
     questions to occupy my mind so I don't continually curse the guy at 
     Audi who put stressed, thin walled polycrapalite inches from the 
     hottest part of the engine.

Sounds like a job for DUCK tape!
