I remember this was discussed a few weeks ago, and you were the one to point out that many studies have shown that ducting materials have very little affect on intake temperatures. This is why I was so perplexed when StephanieT from BEGi was claiming that their data indicated otherwise. But if you read the data she was citing, it was regarding turbo outlet pipes at about 200 degrees F, not an intake pipe at 100 degrees F. Since heat transfer is temperature driven, its pretty obvious that an aluiminum turbo outlet pipe at 200F will tranfer more heat than an aluminum pipe at 100F. This doesn't really need any validating, so I'm not sure why she was trying to compare the two as apples to apples. But regardless...

I fimrly believe that ducting materials have very little affect on intake temperatures, considering how fast the air moves through the pipe. I have yet to hear a good argument, or see data that proves otherwise. Thanks for posting up this article.
