I never heard one personally but I'm surprised that the Champion emits the same noise with or without a load. When the load goes up on the eu2000i the exhaust noise increases significantly even if there is little or no RPM increase from an added load. For instance, with ECO off the eu2000i runs at 4300 RPM with no load, and at maximum load the RPMs approach 5000. When going from no load to max load the engine speed increases only a few hundred RPM but the exhaust noise goes way, way up.
I can't say for certain whether or not it is louder under load. However, the sound is different. I would bet it would look vastly different under a spectrum analyzer. But I bet one of our many champ owners with a db meter could settle the debate pronto.
Along the same lines, the side-by-side comparison between the 2 Hondas and the champ isn't necessarily objective, as I assume they sound very different from each other. Conceivably, one could sound quieter, but actually produce a higher SPL level due to the frequency of the noise.
Regardless, I too was flabergasted, almost devastated when I heard an EU last weekend with the Eco-Throttle off. I was hoping that one day I would have the disposable income to become an owner of one. Now I am no longer convinced that they are significantly quieter. I am wondering if their 59 db rating isn't with the Eco on? I will have to take a second look at their literature.
Same old debate. Only now, I have witnessed it.
