you make it sound like the turbo only heats the air a few more degrees than a supercharger. thats a huge no. a turbo even in its effecientcy range will heat up intake charges at least 150 degrees. sometimes all the way up to 300+ degrees.

the cast iron headers are in direct contact. in direct contact with the uppipe. in direct contact with the turbo. which is a direct part of the intake stream.

lets put it this way. if i run my turbo hard; at night, and pull over. even though its ceramic coated and leaches heat very well. its "red hot" when you pop the hood. no supercharger gets that hott. ever.

this is an age old discussion. which is better. no real answer. just what you are going to use it for.
