After some trial and error with the muffler and fuel tank relocated, this is what I observe. These are only est. numbers and not conclusive. Apx. 80% of the air intake comes from the hand start assy. and 20% from the genhead, that is expelled in the middle of the genset. You may correct me if wrong. The air expelled has good force. My question. In building a enclosure with sound lowering material and supplying air intake confined to the start assy. and genhead, do you believe the air expelled from the genset needs any additional fans?

I have built, used and modified an enclosure where the air intake and air outflow are all open to the bottom.
My results with the muffler located outside of the enclosure:
No additional fan: Temps inside the enclosure reached 170+ on a 100 degree ambient day within 30 minutes run time. Test stopped to prevent damage to the genset.
Small exhaust fan in top of enclosure: Temps inside the enclosure reached 168 degrees on a 100 degree ambient day within 30 minutes run time.
300 CFM squirrel cage exhaust fan mounted on generator head side of enclosure: Temps inside of the enclosure stabilized at 145 degrees on a 100 degree ambient day.
My conclusion:
Hot air exhaust fan or fans are necessary to successfully control the generator enclosure temps. The final cfm and location of the fan or fans must be determined by actual testing of the enclosure.
