Yeah, I'm interesed in the blower info too. It seems like it would be a good mod to prepare for next summer.

Ditto...

If this blower fits, I am willing to replace it and clean out that area. Probably needs to be done anyway. Mine blows poorly as well.

any more info would be GREAT
I've done my own research on the blower motor and it looks like the one that will work for the ZR-1 is the one for a late 90s Pontiac Bonneville/Buick Lesabre. It has the correct plug. The Suburban/Tahoes do not have the correct plug. As far as I can tell everything is the same except for the shaft length, it's longer by 3/16".

I have to wonder is the squirrel cage was used as well, not sure the motor will make a difference but that cage might

Wouldn't the motor have to be more powerful to push more air through a larger area quickly?

only if it runs at a faster RPM at a given Voltage.

Assume you have C60 with the 4 speed fan.. also assume 12V (simpler for the example)

so Speed one is 3v, 6v, 9v, 12v, if the RPM at 12v is 300RPM, then it wil be less at a lower voltage. if the suburban or Bonne fan is faster at 12v then it would work better. If both are the same speed at the same voltage, then maybe the squirrel cage is pitched differently
