From all the cooling problems I've seen and fixed, the ECT will easily run hot and most people don't know it. Then it's on the edge of Limp Mode to begin with.
However, mine experienced LM (new acronym?) one hot summer day after getting on the free. Cursed town driving. And a very long stop light. Car was gutless. After enough air (less hot) was ingested to help reduce IAT's it came back on line strong.
Plumbing in a water inj. kit as we speak. If time allows will get the extra fans mounted also.
Of course, cool-down laps around the pit area, plus hood opened and engine running to keep the coolant circulating until temps drop some. Nothing removed from the car, no tune - all stock. Temps in the 60s. If you're driving hard, heat soak and then limp mode are very likely.

I experienced some heat soak (running Texas World Speedway in June will do it). However; rarely had full on limp mode unless something was wrong. The main issue as we all know is the spineless transmission.

^We have different car behavior- Boost gauges verified I wasn't limping even after 20-25 minute sessions. I was running APR tune normally on 93 gas, mostly stock intercoolers (went to Wagners when the OEM coolers went south). A few times ran on 100 oct just for the fun of it. I probably just never pushed it hard enuff...;0
Running around CoTA- it was not the "hot" season. However; plenty of runs at WOT and never experienced full on limp mode during 3 separate track weekends.

I'm resurrecting this old thread to ask a follow up question: gas mileage.
....I got my 1962 Chevy C10 back on the road after a rebuild of it's 1965 401 Buick Nailhead and did a video of my commute.
I have a ~40 minute commute that is ~35 miles and has three hills to climb. Am I going to get under 15 mpg in an RS6 if I use it as a DD?

1955 Chrysler C300 w/ factory 331 Hemi
1999 Infiniti I30..............One of these is not like the others.
Cruising on the highway I can easily get low to mid 20's mpg. Around town and while hooning I get considerably less.
4.2 liters is not a big engine. Unless you get on the gas very often it shouldn't be too bad. I have an AWD Saturn Vue with 3.5L that weighs almost as much and I can get nearly 30.
I drive from Issaquah to Ellensburg (sometimes Yakima) weekly and that's a few hills to say the least. All at 80-90 mph. My dummie gauge is at 18mpg. If you are light throttle you should do better than me.
