Hi,

Two questions about using the heat to the cockpit from a muff around the exhaust pipe.

 1.  Will the airflow from an intake air scoop be adequate or would I need a fan to draw the air into the cockpit?
 2.  Can I fabricate the collector box with dump valve from aluminium or must I use stainless?

It depends somewhat where the muff is. If it is close to the ports I would
use SS. These device are very dangerous because of CO. You have a water cooled engine
I would use an H2O heater core.
