Never seen temps over 230. And it only got there from sustained illegal speeds between Dallas and Houston or Texas to Arkansas. 220 is usually where it holds to and that's no oil cooler and still quick driving.
I wouldn't mine having one for drag strip days that way I can be closer to 200 deg. So not a bad idea but remember you will probably have more maintenance issues to look for with one, like leaking lines etc.
