I believe my friends 10-71 at 1:1 was 22 lbs.
But not confirmed..He runs Mooneyham blowers.
The one he has now is a 14-71 Hi-Helix Superman but it is a Kolbelco.
At 20% over it makes 36-37Lbs. On the data Logger.
Always but bigger as far as a blower if your budget allows, like someone already said the less you overdrive it the cooler the air.
