Message Due to the height of the GS ICs, and the constricted space behind the ICs, the air trying to leave the back side of the intercooler is slowed down significantly, thus slowing the speed of the incoming air, thus limiting the efficiency of the IC...even if there are louvers, for efficiency reasons, you need the air speed out to be as close as possible to the air speed in. Ideally, this would mean an intercooler mounted sort-of like the hood scoop of a Ford GT...no obstruction in the inbound air, and no obstruction on the outbound air. I realize that we can't mount our ICs like rear-view door mirrors ( although it would be very efficient ). Seems like some type of ducting on the back side of the intercooler ( as well as the front ) could improve this arrangement ( product idea anyone ? ). Just my 2 cents.
