^^^But the heatsoak has to do with the fact it is sitting on a dyno. I can run my car up to 140mph (on a track
) and my post ic temps really only jump 8-10 degrees, while I am pumping in 310-320 pre (22psi with a fp18g). I have even tracked my car with my tdo4 at 20psi (325) and my post temps never went over 110 (ambient was about 80). Track sesions usually lasted about 12-15 min. But again, with a good seal between the scoop and ic to force the air through the ic. I think the key to a tmic is keeping the underhood temps as low as possible and keeping cool air flowing though the ic.
