I'm not racing the car, it's simply a daily driver that doesn't get WOT all the time, here and there but isn't getting anywhere close to racing temps. I think with constant flow of good air it won't heat soak but i'm just wondering how badly they get when used. I know everyone bad talks the SSIC set up and all but if it's daily driven i don't see how even the smallest IC can get so badly heat soaked it can't do any good.
