Quick comparison at a glance of all the cars at Fastivus for coolant and IATs.
@yakboyslim has a Mamba GT2867R (running lower boost than typical IIRC?)
Ashton has an IS20 and FMIC. He was definitely getting oil ingestion related knock so it may get discarded at a later date.
@tigeo has an IS38 wagon
I've got a basic IS20.

Despite the large power disparity...
@yakboyslim 's overall top speeds were near identical to mine with an IS20.
@tigeo had the highest top speed. I had higher average TPS %, but they're all roughly within noise of each other. I'd expect a higher horsepower car to have a bit less time spent WOT. Similar to comparing mine and
@Mini7 at VIR. He's got at least 40ish more hp than me, registers about 6% more TPS avg... likely because he spends a solid 3+ seconds less on the straights, plus having to brake a bit sooner due to a +12-15mph top speed. Rough napkin math says that there will be 2-3% less time at 100% WOT there alone.
Realistically they're all terrible cars and oil is borderline too hot. The Shenandoah Circuit is pretty tough in that it's a LOT of turns (so lots of throttling out), and overall lower speeds so there's less airflow for cooling.
I think a big part of
@yakboyslim 's temp success is 6MT + conservatively tuned. Also needs more skinny pedal
