I installed my LFP Heat Exchanger today. Install was very straightforward, all hardware needed was in the kit (though there wasn't much needed), and the instructions were clear and included pictures.
Prior to the install, I got the car good and warm (ie...heat soaked), and did a ~30 minute drive that I logged on my Autotap PDA. I then changed the HE, and did the same with the LFP unit. The results are below. The files are .csv format, and can be opened directly, or saved and viewed with MS Excel or Notepad. Please note that the files aren't physically big (about 180kb each), but they are quite long:
Stock HE Log File
LFP HE Log File
The last column of both files is the difference in Deg F between IAT1 & IAT2. The average for each column is at the very bottom of the file. Highly recommend scrolling down and taking a look - the data is rather surprising.
Both trips were the exact same route, and ended up being within about a minute of each other in length. Traffic was similar for both runs. Air was also simliar: Ambient Temp/Dew Point for the first run was 80F/62F, for the second was 81F/63F. It was cloudy for the first run, and partly sunny for the second. With the temps being close, that probably didn't make much of a difference, though it might have added a bit more heat to the road, and thus the air entering the HE might have been a bit warmer on the second (LFP) run.
Of note, with the LFP HE, there is a significant difference in the amount of flow through the reservoir when the pump was on. Don't know if it makes much of a difference - but might be a factor that would help keep temps cooler with a large aftermarket reservoir.
Also, please note that my data is pure street driving, no or very little boost - ie, I drove conservatively. Some have reported much larger differences in IAT2 temps on the dyno and at the track.
For those that have the time, I'd appreciate it if you would go through the data and provide your opinions/conclusions.
Thanks.
