heat of the summer ac upgrade

[waxdnuggz]

Ive been pondering the thought of "upgrading" my blower motor for my ac. It blows cold and decent pressure but I feel like it could be better

1st before I put some serious time into this has anyone already done anything of the sort. Or added a resistor or something somewhere to do this?

2nd would this hinder the cooling capabilites of my system or cause it to heat up more because of needing to remove heat from the extra air ingested

3rd my thoughts were to pull a new motor/blower assembly from another car. What would I reasearch (key words) to figure out what blowers/cars actually blow harder then ours. Cfm ratings? Is there charts that have ac cfm rating from the blower housing? I would assume thats where you have to messure because measuring from a vent wouldnt give accurate reading. The reason for this is what I call a funnle effect because of cars not all having the same number/size of vents.

The funnle effect i speak of is like when you use attachments on a shop vac. A big hose may not pull as hard as if you put a needle attachment on it. Get what im saying?

Surely in the almost 20 years our cars have been out someone has thought of this? If not where do i start?

All the blower fans I have seen seem roughly the same size. Maybe freeing up the intake side of the ducting and using a low restriction filter (if you have one) might help.
There may be a way of increasing fan speed, but the increased noise might not be fun.
The AC evaporator can only produce so much temperature/pressure drop for its area. Moving more air through it will cause the compressor to cycle less and/or pressures will not be as low, and thereby the output temps will be higher.
Good luck.
