I finally got around to taking some pictures of my intercooler shroud. The GT2 tail has a huge surface area, I am certain that no air was going through the intercooler. It was simply a heat sink sitting out in the air.
A very thin sheet of stainless was used with a hole cut in it to fit the intercooler core. Foam rubber was glued to the S/S and formed to fit the intercooler. The back end of the square hole was left open to allow air to be pulled in toward the air filter and to not choke off the fan.
The results were no less than spectacular. I picked up a BUNCH of power, lost a LOT of lag, and raised the engine temp from 150F to 190F. The engine actually runs better. Too much cold air was engulfing the engine compartment and cooling the WUR and sensors causing the fuel pressure to be less than optimal.
