Hey guys have any of you upgraded to a bigger blower motor or squirrel cage in order to get more air flow out of your A/C system. It seems like the air ducts just don't have much flow compared to a newer car. Do you know of any way to upgrade this with parts from a newer model or aftermarket stuff. It may be the case that the evaporator may not be able to deal with the extra flow and the air will just come out at a warmer temp. Have any of you guys toyed with this?
