Generator quieting
I have a Honda 3000 EM, I am looking for some ideas to quiet it down. Anyone had success with this, want to share some ideas?

Don't go to your room.
After a little bit of experimentation with cardboard and masking tape, I have used a roll of tape and all the cardboard in the neighborhood. the Jauguston design runs too hot for my comfort zone, unless his 2000° insulation is somehow dissipating heat in a way that I do not understand.
I can easily get an ambient air temp in the 90's in the gen box at the inlet side of the generator, the exhaust end at the separating wall, on the "cool" side of the wall will quickly rise to 120° (temp measured at base of handle on exhaust end) without the fan assist in any ducting resembling Jauguston's. The temp in that area will drop to a few degrees above ambient when genset is taken out of box.
Also in my tinkering if I route the engine exhaust separate from the cooling air the temp of the gen set goes up. That has me completely baffled??
After experimenting with this for a few hours it is obvious that your adaptation of this design does not have this issue. Your exhaust end will only be a few degrees warmer than the inlet temps as you are not restricting airflow. Any restriction to the exhaust airflow quickly raises the case temp of the genset.If you have the opportunity the temps on yours would interest me.
Then remember I started this going with a different design so have little room to change it, if I were to make any change it would be a more powerful fan, plus I need to get done and get out of town!
Also the noise barrier from West Marine is the same as Soundown It likely is Soundown with a different name, which can be bought online for $50 sheet less! I purchased mine from IBoat for $80 sheet including shipping. There are also more than 1 type of insulation's available. So needs some research.
Your input is greatly appreciated. I would not have thought of isolating the inlet end from the exhaust end which is a big improvement.
