Old Koreelah Posted October 18, 2008 Share Posted October 18, 2008 I have found a hopefully reliable article on the net which recommends the best temperature range for VW CHT's in order to ensure long exhaust valve life. This authority recommended 412-428Â°F as acceptable on climb and 338-345Â°F on cruise. My problem is that when testing my cooling modifications with ground running, all four cylinders rapidly climb to 420Â°F. I can't find a recommended temp for this mode, but it does seem high. Any advice? Regards, Old Koreelah Link to comment Share on other sites More sharing options...
