I cannot look at these designs without thinking of overall operating temperatures of the generators. Has anyone placed any type of thermometer inside to read operating temps? Since by design, intake air adds to cooling where are the air intakes on these boxes?
Prior to my attempt I'd searched for others (missed some:) & if you search you'll find (sometimes anecdotal) info on their experiences e.g. "used this about X times for about X hours & working fine". Some talk about intake/exhaust/baffling can be found.
I'd checked gen case temps for my initial design in/out of box & they'd been "fine" the few times of less-than-heavy testing I'd done. But temps got too high for my comfort during a heavy/max load session (running A/C that just had an EasyStart installed).
I'm modding the design to have single intake fan w/about 2X the CFM (240) & larger, passive, 12" long cut from a steel mailbox for exhaust port/exit. Will do more thorough testing / temp measurements of that design. Will get to it in a couple/few weeks & expect it to perform pretty well.

I love this idea, we have a pair of Honda EU2000's and I usually only operate one unless I need the AC. I would love to know how much the DB readings are after the box.

Posted this info for my initial design in my instructables dot com project. IMO the noise reduction was well worth the effort as its not just about ave DB but frequency profile & any box should reduce the most "offensive" mid- & upper-frequency components of the noise.
