Old rad would climb to 195-200. After a run down the highway sitting in my driveway would climb to 210, same as old rad, where I shut it down. I'm hoping it will get better when I dial in the tune a wee bit better.
Do you have a spacer behind the fan? It would work better with the tips outside the shroud.
