It is time that I tackle the cooling
(or lack thereof) of my 200A alternator
. Before I hack a vent hole into the engine
cowling, I would like to attempt to increase airflow through the existing ducts. I have two 3" ducts to the engine
compartment. One for air intake and one for air exhaust
that has an inline extraction fan in it.
I would like to add a fan into the intake duct and possibly replace the exhaust
fan with a higher volume unit.
All the fans I have been able to find are in the 140 cfm range which really doesn't do much for me. Has anyone seen or used a 3" duct fan, 12V that is over 200 cfm or maybe even more ?
