Come on guys, take it easy... it's hard to have a good thread with lots of good data when people are at eachothers throats. People have opinions, and a lot of times those opinions are correct even when the person can't present the data to back up their claims.
Apocman- This message board isn't the absolute BEST place for technical data... it's been proven time and time again. I suggest looking elsewhere if you really want charts, numbers, diagrams, etc/whatever... not flaming at all, but there is a lot more info to be had just by taking some physics classes to get a grasp on the basic fundamentals of heat exchange, and then learning the differences in construction between bar/plate cores and tube/fin cores. After you know the differences, you can use your own judgement to decide which one is better. I bet 10:1 that if you actually did that, it would be more than clear to you why bar/plate is the better choice for most turbo applications.
Sorry for not providing any charts and whatnot, but I don't have a source that just outright tells you all of the stuff that is in play here. After 4 years of advanced physics and working/studying at Los Alamos National Laboratory, it is pretty obvious to me that bar/plate is the overall best method of cooling air that is coming from a turbocharger.
Any flames from anyone can be directed to my PM box, let's let the people who actually HAVE the charts and info post it up for Apocman to see... no need to turn this into a pissing contest.
