were trying to get our water temp down from 230

There really isn't a good way to tap into the oiling system externally. Where is your rad located and are you still running a fan through it? There should be enough surface area with the stock rad and modest airflow to cool the motor during racing rpms. Having you tried switching to an enhanced cooling medium like Water Wetter or Ivan's Ice? These types of products reduce the surface tension of water and anti-freeze allowing them to disseminate heat better. Or do you have space to run two rads?
