Since I've just solved my data acquisition problems, I'm hoping to get real track data (as opposed to "street" data). I'd like to try the heat shield. I don't know whether shrouds on the exhaust side of the IC would help... but there are a few threads about installing pusher/puller fans. There's another solution out there that replaces the factory IC with an aftermarket IC located near the side scoops... and it sounds like its had some success.apk...the aluminum heat shield between the top of the engine and the IC...I was thinking the same thing. It would have to be of some help. Also, if one could fabricate another shroud on the engine side if the IC and duct the air directly outside...maybe with a puller fan or two to help it along...
