With some careful design work, those temps are easy to achieve. Mine actually runs a little cooler than that. With the current set-up, my water temps are about 180-190 and oil temps are 205-215. My radiator is a big thick two pass aluminum unit, much like the ron davis units. Make sure thatit is installed so that it doesn't allow air to escape around or over it. The oil cooler cannot be mounted to the radiator (zip tie style). It soaks too much heat that way. Hope this helps.

Earl, let me know if you need anymore specifics on anything..
