DA-100
 
On a custom very quiet (well baffled) muffler:

brand new engine, without cooling baffles in cowl:
4650rpm on a 28x10 MZ

run in engine, without cooling baffling:
5000rpm on a 28x10 MZ
5700rpm on a 27x10 Mejlik
same rpm in the air

run in engine, with heavy cooling baffling:
5800rpm on a 27x10 Mejlik
rpm in the air seems (though has not been instrumented) 300pm+ higher, so 6100rpm+ in the air
