I know guys that would kill for your running temperatures. If it works don't mess with it. Visit the "Walker Radiator" site and look at FAQ's for more info if you wish. I had my radiator looked at by their main guy Buddy at NASA Nats at Louisville in August several years ago. He ask if it was boiling over? I said no, it seems just to be running hot. He patted me on the back and said, "If it ain't boiling over, it ain't to hot. Next person please! Remember, water boils at 212 degrees. You get about a 3 degree jump for every psi you cap is rated for, ex. 15 psi cap= 45degerees, so 212 + 45 = 257 deg.
