I may have missed something (and I've never tried to read one of these cameras before), but I believe what you are showing in your last post is a bit misleading - you've stated that temperatures have been reduced ~40* in some cases. While this is true for some parts of the DP, other areas have gotten significantly hotter. According to your other post, the following is true:
Turbo @ idle w/o wrap: 358*
Turbo @ idle w/ wrap = 370*
downpipe @ idle w/o wrap: 170* (one tiny spot that's ~325* - call it an average of 255*?)
downpipe @ idle w/ wrap: 312* (Whole lot of ~300*)
Turbo after driving w/o wrap: 497*
Turbo after driving w/ wrap: 497* (These look like the same picture, also same timestamp?)
Downpipe after driving w/o wrap: 248* (one tiny spot that's ~500* - call it an average of 375*?)
Downpipe after driving w/ wrap: 456* (whole lot of 456*)
Based on these images, it seems like the small spots of high temps are gone, but there are higher temps overall throughout the pipe. Instead of having a small concentrated area of high heat, you've spread it around and increased the heat in other areas; overall, the rest of the pipe is hotter... This makes sense as the wrap is designed to retain heat.
The heatshield and intercooler do seem to be cooler.
Nice work. Thank you very much for contributing this.
