Let's get back on topic. This isn't a "hood scoop placement" thread. Unless it's being run on a car in the logs.
Anyway:

For some context:
I asked q74 about relative pace
Awesome! I take it the second session you were driving harder?
On these logs, just checking but were you new to that track, not driving very hard for whatever reason, etc? Would you consider yourself "fast"?
I only ask because when it comes to temps and stuff, people who aren't on throttle as often just plain won't have as many issues.
To which he responded:
TL;DR: Car can do 1:36, those logs are in 1:40 -> 1:45 range, about 3 to 8 seconds off pace, and one of those 2 days is wet.
I choose logs with more ODB2 data, and one of those two days it was wet/raining. These are from DDT, which is a very tight technical track, which is hard on tires and brakes, but not really much of a speed. The car (in set-up as of the dates of those logs) is capable of a 1:36 when driven full on hard with full shifting where appropriate at that track, but in those logs are in the 1:40 ->1:45 range with no shifting (3rd gear only) so I'm hitting rev limiter a lot - if you look at throttle position (which oddly maxes at 87% or w/e) you'll see foot is down but car no-go, lol.
Anyways, I don't have past logs with as "full" obd data where it was driven full-send, but from what I can recall, the temps for coolant and IAT were roughly same, but oil hits 135c after 1 hard lap.
I have converted all these to F - because I found that if you try and use C difference, anyone converting to F ends up with +32F over what the true difference is. This is because the formula requires both Ambient + IAT to be converted via (TEMP C *(9/5)+32). This leaves you with a ~10C difference for example. If you take that straight difference and convert to F, it shows 50F difference. But if IAT is 30C, and AAT is 20C, those correlate to 86F and 68F respectively. Obviously not a 50F difference.
Also due to the different data source I am using PUT along the left axis. Since OBDII "throttle" is actually not the PEDAL, but is the throttle blade, I have the WOT only configured to only display data above 65% (maxes at 86% which is true WOT).
This is the data from the SECOND of two logs he sent. I'm ASSUMING this one is the dry day which would be more applicable because: higher top speeds, higher lateral Gs, and higher average throttle position. Also higher temperature deltas.
Summary: bear in mind this is a STOCK tune, but as you can see the IAT vs AAT is not terrible at all. For a point of comparison my bone stock *GTI* (IC, rad and all) was seeing 40-50F over ambient on a 78F day. Clearly it appears the AMS IC is working.
However we will also look at the general temperatures of the coolant: it averages out to about 223F over a large portion of the session. Min 215, Max 230F. Again this goes directly against everything that the CSF marketing claims. And keep in mind this is likely close to a best-case scenario: STOCK tune, just an IC. They "claimed" the following:

AFTER INSTALLING THE RIGHT-HAND SIDE AUX ENGINE RADIATOR (CSF #8132) TO COMPLETE THE ULTIMATE COOLING SOLUTION FOR THE MQB MK7 GOLF R, RESULTS SHOW THAT THE COOLANT TEMPERATURES WERE MAINTAINED IN OPTIMAL RANGE (W/ PEAK @ 212°F) THROUGHOUT THE ENTIRE DAY REGARDLESS OF THE AMBIENT AND TRACK TEMPERATURES. WITH THIS ADDED COOLING POWER, ASH NOW HAS THE CAPABILITY TO TRACK HIS GOLF R IN EXTREME CONDITIONS INCLUDING LONGER AND CHALLENGING RACE TRACKS WITHOUT HAVING TO WORRY ABOUT COOLING ISSUES SO THERE’S DEFINITELY MORE ROOM TO PUSH THE CAR TO ITS LIMITS.
I know that q74 is headed to the track later this month (and now S1 tuned) - so it will be interesting to see follow up data on this.
