Pressure for blowouts

So now its transition time, moving to a new company. I have always done blowouts with a 185cfm tow behind and 1" air hose and now I will be using a gas powered roofing compressor. I have heard that you have to run air at a higher pressure due to small orifices and low flow at low pressures. Basically using the main line as a storage tank. I have always stuck to no more than 60 for the typical resi system and no more than 80 for the comm jobs. Any experience with this? Thanks, Corey.
