I have another picture on my home computer that shows more intercooler detail and that only the turbos charge pipes connect to the intercooler. I will post it when I get home. From that picture you can see that the superchargers outlet isn't feeding anything. More than likely though it would have lead to a bypass valve that would have fed the turbos.

A great read on twincharging

edit: Also, someone else with a camera would have been at the 2001 TAS and taken a picture of this, right? Why is it so hard to find pictures?!

why would you twin charge a 4AG? it completely screws up the nature finesse of the motor not to mention it still wont make any useful amounts of power.

at least with even boobs you dont just have one looking at you while the others are occupying you elsewhere. and i dont want to meet the chick with only one boob. with even there is at least a sense of normalcy.

lmao the fact that I'm am cracking up laughing right now is proof of my immaturity. four boobs is just as gross as one and I refuse to compromise. Haha we'll get owned if there are any breast cancer survivor women who like 240's. Really though why would you twin charge a 4AG?
