Overkill much?

Agree on the first part, but not necessarily on the second. I'm looking at datalogs I've done and IAT2 comes back down to pre-boost temps within a minute at highway speeds. Of course, this is on a stock car but I have no idea what mods you guys currently have or are planning that are making you this concerned about heat soak already?

JRE is just looking at IAT2 rise over 10 seconds, where the roadcourse people are trying not to boil all the fluid in the system. You are trying compare apples and oranges. Just like the others are saying, the more fluid in the system the longer it will take to boil. No it won't change the increase in heat between IAT1 and IAT2, but it should allow you to run longer before the fluid overheats.

Well said. The part that seems kind of strange to me is that at stock or near stock power levels (read that as blower speeds) the stock system is up to the task per GM and reputable sponsors on this forum. It's as soon as folks start cranking up the blower speeds and introducing all that extra heat they start to have problems. And at that point, one must ask themselves....is all this extra power really what's going to get me around the track faster?

Based on what? I haven't seen a single thread with any data about IAT2 temps with the Heartbeat blower?
