My question is why are you replacing it? A larger radiator does not necessarily mean better performance in this case. Yeah, they look cool I guess.
Skip, at this point I don't have any real data (no test sessions yet) but my (unreliable) butt dyno keeps telling me that the car is now more sensitive to ambient temperatures. It may well just be the result of my expectations, or wishful thinking, but the car seems to be noticeably faster when it's 37-degrees than when it's in the mid-70's. Is it just me (and my imagination) or are the supercharged cars noticeably faster when the temperature goes way down.
XViper, I know "way down" has an ENTIRELY different meaning where you are, but once the temps go much below 40 I start getting concerned about keeping enough heat in the tires. Do you see a power difference when the temp changes 40 degrees one way or the other?

thanks for the responses so far!

I never said they didn't add any extra cooling. I'm no guru, but I do remember a discussion about radiator size vs. pressure loss. I believe the conclusion was that the CT radiator was optimally sized for most applications.

In theory, yes. The colder the air, the less agitated the molecules are. In this regard, the same amount of mass takes up less volume. Since your intake doesn't change sizes based on air temps, you can get more air into the engine. Getting more air and fuel into the combustion chamber allows for a more powerful explosion in turn forcing the piston down more forcibly.
If cooler air temps weren't a concern(for whatever reason), aftercoolers wouldn't be necessary.
