I've insulated the hell out of my car. I added underdash A/C. It's still not enough. I wish I had one higher fan speed on the A/C and then I think it'd help. I was thinking of finding some 12v fans and hooking them up behind my dash maybe to get some airflow going. Do any of you all have some tricks besides the vent windows or air boxes? Actually I have an extra electric cooling fan or three I could mount somewhere. I saw an old Buick at the junkyard and it had a fan in a shroud underneath the driver's seat. That doesn't seem like a bad idea, and not much different than the air conditioned seats in the '09 Cadillac I rented! I've saw a couple small electric fans on the condensers of late models at the junkyard, that might work and keep the noise down to a dull roar! Anyone? Or am I the only wussy that can't take the heat?
