Rotec CHT issue

[7CylinderJim]

I have recently installed the Kitfox-supplied bump cowling on my Kitfox SS with the radial Rotec engine. I am experiencing pronounced CHT increase (450 degrees F at cruise) and wonder if anyone out there with the Rotec engine has experienced similar issues.

That is really high. What were your CHT's before and what cowling setup did you have?

I'd be interested in a couple things:
-what were CHT's before?
-what is the gap between the rear of the bump cowl and the rear of the engine cowl?
-do you have any inter cylinder baffles?

Can you attach a few pictures of the cowling?

Thanks
