I think Keith is correct in its reason for being, but once on track your oil typically will be hotter than your coolant, so the cooler will be dumping a lot of extra heat into the oil that would be better addressed with a separate oil/air cooler.

That was my hunch. I'd hope that my oil temps are not exceeding the coolant temps. Hopefully I'll be down around 200-215 on the track now.

The coolant reaches operating temperature before the oil does.

I'm in the process of wrapping up a cooling system re-route and had decided to disconnect the stock oil cooler/throttle body heater circuit. Given that I was seeing 225 degree coolant temps on the track pretty regularly, I'd think that the oil cooler would be doing more heating than cooling. However, since I don't yet have an oil temp gauge, I don't know what my oil temps are. Thoughts? Thanks! Shaun
