I think i experienced heat soak in the car and just wanted to be sure. I never really understood what the issue was with heat soak but i can see how dangerous it can be. I was driving in traffic with the ac on for like an hour. My lane was at a standstill and i had a window of opportunity to switch lanes and head for an exit. In first gear I gunned it but no response from the car it kind of rolled into the other lane lagged a bit then finally took off. The car in the other lane almost hit me because i just literally had no speed. I have experienced this a few times before but not as bad. So is this heat soak?? If so i will def look into an fmic. I currently have the frpp power package and fswerks turbo inlet.
That's a pretty extreme example if it was all due to "heat soak". First we need to make a distinction. Usually, when talking about heat soak, guys are referring to a heat soaked IC. And usually they're talking about a stock IC. It's a situation in which the IC has reached equilibrium temperature and cannot cool the air charge to any greater extent. Ordinarily this occurs when you've been under boost for some time, and varies with the ambient temps, among other things. Simply sitting in traffic on a hot day is not likely to push the IC to it's limit.
There's another kind of 'heat soak' that simply makes reference to the overall engine temps. But, what you describe seems to be more than either type of heat soak mentioned. Your car should not lose power to the extent you described. The car's ECU can dial back power to what's called "limp mode" should it detect a potentially dangerous set of circumstances. It almost sounds like what you experienced. I haven't experienced limp mode, but I assume it would throw a code. Perhaps one of our tuner's or engineers could give you some advice. Something besides, or in addition to, "heat soak" seems to be at issue here. JP
