I bought a 450 CFM blower for my Dry wash.. it says 200 mph but that's only with its attachment that narrows the air flow. in the research i did Pryor i found that most people were running 350cfm to 450cfm.. but not many ever mentioned speed. Hope it helps...

Good day ,

The CFM is more important. The CFM is the volume of air moved which is totally dependent on the blower size and design. You can't increase CFM by changing nozzle sizes of shapes. You can increase MPH by changing to smaller nozzle size, as air squeezed through a smaller area will increase in speed but will never increase in CFM or volume.

I hope that makes sense,
Chris
