Default More air thru ac vents

I'm looking to increase the CFM thru the vents. Everything is fine, vent doors, blend doors. So Im only looking for information on where to find a higher flow blower motor.

Floor vents? Defroster vents? Rear vents? Seeking increased airflow suggests that everything is not fine with the HVAC system.

More flow can only be accomplished by increasing the blower speed or increasing the size of the blower. So, your options are to play around with different resisters to increase blower speed (at the risk of burning something up), or increase the squirrel cage size by modifying/installing a different blower housing that would accept a bigger blower. But then you get into the limiting factor of the duct size which is designed for the existing blower.

Might just want a factory vent system that works properly, my 96 blows so hard I never turn it past 2 clicks on the speed dial or you can't hear talking to the passenger . On full I never need the rear ac and it blows my hair back . My 2003 and 13 were the same way .
hate to see someone go through modifying a blower motor to find it was a broken mix door .
If you need more than that good luck !
