 Ed,
 
 Compressor discharge temps (measured before the intercooler) cover a
 large range of temperatures.
 
 On a cold day at sea level,  they may only be  120dF or so.  On a hot or
 cold day at 24,000 feet,  they may be 230 to 280F.
 
 Does that help?
 
 Regards,  George

 The reason I was asking George the "approximate" discharge air
 temperature of the turbo is because after talking with Charlie Kohler,
 we decided to make a large box to receive the air coming into the cabin
 via the mixer valve so the air velocity had an opportunity to slow down
 and hopefully decrease the noise that normally comes from the valve
 presently used. Plus, it will give us more room at the back of the radio
 stack.  Looks like I can make this box approximately 12" long x 5-1/2"
 high X 2-7/8" deep and fit in the area we have available
 We want to make the box out of 2 bid prepreg honeycomb material, as well
 as the flapper for floor / defrost deflection -  IF  the temperatures
 aren't too hot for the honeycomb material.  I just don't know, so I
 thought the group might be able to help.
