From this data it looks like with 5w30 and no oil cooler, oil temps get up to ~275F and pressure is ~7.5 psi/1000rpm.

WITH an oil cooler and 5w30 oil, temps are down around 250F, but pressure is still ~7.5psi/1000rpm.

Theory: increase in pressure from cooler oil is exactly negated by the pressure drop from the cooler itself, maybe?

Anyway, I haven't seen any evidence that I *need* an oil cooler for my track usage, so for me, IMO it's not worth the cost/effort/risk of having one installed.

Where are you seeing people get temps of 250F with an oil cooler? In high summer in South Texas I see temps around 220F on track with a dual-rad oil cooler, I strongly doubt anyone running a standalone oil cooler is going to exceed that. Based on the chart you posted, it's pretty clear that pressure is nearly double with an oil cooler given a hot temp of 220F.
