Darley Champion Giant Tornado Siren Test - Steen, MN. 

I think these models in general have that undertone.

The rotor has 4 long vanes and 4 short ones. They are basically like a shrunken down version of an older 8 port Federal rotor. Sounds similar to this Sentry 7V8 being overdriven by a VFD: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-w_1Gvn0rAb4.html

@@PeeFifteen This siren is indeed 8 port.

@@polandball7482 Nope. Apparently these have been wrongly called Darley 3V8s this whole time.

Idk bro. “Champion Giant” never made sense to me either because of the 7hp Champion existing and this siren having the average output of a Model 2.
