Thanks to everyone and, keep the ideas rolling in.
Im really torn on the HHR fan vs one's that have advertised cfm ratings.
We are using the Meziere pump ( thanks for the advice moparts) that fits in the mopar housing, we have the aluminum one from 440 source.
It gets really HOT here in Texas - (will be 99 here today) , late June, all of July and August are really tough and it seems to get a little worse each year or, maybe getting old just seems that way- grin.
I'm wanting to leave at 165 consistently if I can pull that off, thats where we have made best power with this engine.

I cannot seem to find any real data on the Cfm rating on the HHR.
