Well... I am still on my vacation, but managed to find a PC for a few minutes. With my larger exchanger, and my recent visit to Campbell Automotive for a dyno tune, ambient around 30*C, intake never got more than 55*C according to dyno guy. I have no paper work to prove this, just what I remember him telling me. He was also able to add 4* timing to all boost areas instead of removing any from Superchips stock tune. I have been towing for 4000 km as of today and in some 38*C weather(hot), no knock retard. Runs very strong. However, I did have to buy some used fan shrouds and fan to replace the electric one, truck was running very hot on long hills. Ever since the manual fan, temp guage never moves. DO NOT run electric fans when towing, just like the fan manufacturer says... DUH.
Anyways, I can not say the larger intake before and after temps, but beleive it helped in why he could add more timing. Can not hurt intake temps. Only thing it may hurt is air flow through it to cool coolant radiator. Mine seems to run very good now since tune, shifting is great, fuel milage okay. Dyno was 395RWHP at 5500 RPM, and 415 RWTQ at 4200 RPM. I like it alot
Will be back online in another 8 days or so.

I actually just went to electric fans and they have kept my intake temperatures at 130 or below now. The temps would get to 150+ with out the electric fans. I haven't tried towing yet, but The most I tow is about 5K so I am not too worried. Oh and the outside temps around here are 100+.

Nope. Meant CTS-V. I got that from the installation manuals on their website. Look through the 04-05 one for CTS-V and find the pic for the exchanger. That is what I got.
