One thing that hasn't been mentioned. Seal off the radiator so the air has to pull through it and not around it. Air is like water it flows to the easiest path. If you have gaps between the radiator and support and shourd close them up with some type of sealer. I use the black foam to seal off around it. It will work wonders for the cooling effect.
Timing will also help if it's not set right.
