Fan shroud is for a PMG-132 (definitely NOT the ETEK), there are no significant air passages nor any significantly heated elements under the brush cover (I have been checking temps), therefore I am attacking the area where the greatest heat source is accessible, and the greatest airflow is possible. Also by pulling the heat out of the outer ends of the rotor my hope is to wick out heat from the core, avoiding any heat saturation.
If you go to the PMG site you can see how they designed the outer housing, unfortunately the brush design is not evident there. When I finish the shroud and disassemble the drivetrain to mount it I will have the brush cover off, and take some pictures to pass along. From everything I have seen and y'all have experienced with the ETEK I would spend the extra money for the PMG-132.
