I duct-taped off the fang intakes for one session (2nd of 4 sessions on the second day) as discussed earlier to compare. With the ducts closed, about 2/3rds into the session I was getting some front pad fade and extended braking distances. Also had one hiccup of ice-mode late in that run that was easy to correct quickly with the pedal. Un-taped the fangs for the next run and the system went right back to zero fade for the rest of the weekend.
I did get the rotor paint and caliper strips shipped to me in time. I ran the same spot of Genesis rotor paint all weekend. It stayed in the "bright red" range (679-804F) all through my first 5 sessions with the ducts, then it bumped up into a somewhat browner color (804-1074F, probably at the lower end of that range, not a huge change) for the one run I taped off the ducts.
I put the Alcon caliper temp strips on the outsides of the calipers (over the Nissan logo) and they never even blacked out the lowest section (250F), regardless of the duct situation. So either my caliper temps are awesome anyways, or it's just stupid user error with me putting the temp strips in the wrong place (do they need to go elsewhere to feel the heat, and/or does the thick grey nissan caliper paint insulate them too much?).
In any case, pretty pleased with the results  |
Your rotor temps are in-line with what I would expect for your setup. Instantaneous surface temps on the face of the rotor are several hundred degrees higher.
I put my caliper stickers in the same place, got the fronts up to 400F which can be enough to boil the stock fluid, on one occasion I did see 450F. Ambient temperature does play a significant role in that as well as session duration and track layout.
Good results for the ducts I would say.
